CTM KOYUK 3.0 28 bike, matte black/shiny black

Variant CTM KOYUK 3.0 28 bicykel, matná čierna/lesklá čierna

I didn't really want to write a review, but I decided to do it hoping someone from CTM would read this review. To start, I'll say that I've had the bike for 3 months and have ridden about 800km.

I'm wondering where to start...
As @Papaccos wrote earlier, I am also a fan of CTM and this is my third bike from this brand (I had an even older Caliber and I currently ride a Skaut 3.0, model year 2022 with several modifications or component upgrades).

But back to Koyuk, which I was really, really looking forward to.
The 3.0 version was the obvious choice, especially because of the 1x12 drivetrain.
With my height of 195cm, I took size 600.

Already in the MTBiker store in BA, where I tried out and received the bike, I was a little surprised by the aforementioned missing caps on the frame holes. A detail, but it's a shame that CTMko didn't care about it... The second thing that bothered me were the missing screws on the fork. Out of 6 (3 on each side), 2 were missing. It looked really strange...
Silver plastic plugs on the rams... a bit of a step too far... I immediately replaced them with BBB BHT-96 ScrewOn. The same goes for the wrap over time...
The derailleur cable was so long that it was cutting into the cable itself while riding and shifting... Again, it's just a visual aspect, but it's not pleasing on a new bike...
These are just visual flaws that can be easily fixed and we move on...

It was worse with the bike itself in operation before all the adjustments and fine-tuning after the first kilometers...
Unfortunately, I have to say that despite the fact that this is the highest level of gravel from CTM, the preparation from the "factory" is disastrous.
A dry seatpost, a dry stem, dry everything you can imagine... and most importantly (and I didn't expect this) a completely dry "head" - a chapter in itself...

For the first 100-150 km, you won't notice any problems, but as you drive further, you'll start to hear noises, popping, creaking, and everything else you don't want to hear while driving.
All removable things so I started the service. I replaced the bottom bracket with Shimano Ultegra SM-BBR60, adjusted and lubricated what was needed. All contact surfaces as well as threaded joints... But what I didn't think about, that is, it didn't even occur to me that I should disassemble and check the headset...

Since the cracking and "grunting" when pedaling didn't stop, and I couldn't help myself anymore, I took the bike to the guys at MTBiker for a checkup.
I'll cut it short... after 3 services (including warranty) and a 100€ bill, the guys finally found the cause, which was the aforementioned headset... It's incomprehensible to me that such a part of the bike was left untreated when assembled... A big shame and a defect that cost me quite a bit of money. The guys from the service were also shaking their heads... The dry headset was causing all those rattling and cracking noises to be transmitted through the frame to the drivetrain, and we were looking for the problem somewhere "down there" the whole time.
Anyway, equipped and for me a good service experience, that even a new bike has such shortcomings...

Counted and underlined...

I really like this bike!
The geometry suits me and I feel very good on the bike. Especially after the bike fitting, which was conducted by Matej from the BA store, for which I thank you very much. It was a great experience, valuable advice and a lot of interesting information.

After all the shortcomings have been fixed, Koyuk is an excellent partner both on field and forest roads and on asphalt, where I have ridden it the most so far.
The components are really high quality and in the higher range, which I believe will also be reflected in the service life (of course, with regular maintenance).
Despite the fact that it is not a premium brand or model, it is certainly an excellent entry into the world of gravel and partly road cycling...

My overall rating of 3/5 is mainly due to the "readiness" of the bike and the unfinished details, which are really a matter of a better approach and willingness to give the customer the best that CTM has to offer in a given segment.

I believe that CTM will pay more attention to how their bikes are delivered to the customer.

Many happy kilometers to everyone!

Veľmi sa mi do hodnotenia nechcelo, no s nádejou, že si túto recenziu prečíta aj niekto od CTM som sa do toho pustil. Na úvod poviem, že bicykel mám 3 mesiace a najazdených niečo okolo 800km.

Rozmýšľam, kde začať...
Tak ako @Papaccos písal už skôr, aj ja som fanúšik CTM a toto je môj tretí bicykel od tejto značky (mal som ešte starší Caliber a aktuálne jazdím aj Skaut-a 3.0, ročník 2022 s viacerými úpravami, resp. upgrade-ami komponentov).

Ale späť ku Koyuk-u, na ktorý som sa veľmi, veľmi tešil.
Verzia 3.0 bola jasná voľba, najmä kvôli pohonu 1x12.
Pri mojej výške 195cm som bral veľkosť 600.

Už v predajni MTBikeru v BA, kde som si bicykel skúšal a preberal ma trochu zarazili už spomínané chýbajúce krytky na otvoroch rámu. Detail, ale škoda, že si CTMko na tom nedalo záležať... Druhou vecou, ktorá ma mrzela, boli chýbajúce skrutky na vidlici. Zo 6tich (na každej strane 3) chýbali 2. Vyzeralo to naozaj zvláštne...
Strieborné plastové záslepky na baranoch... trochu krok vedľa... hneď som ich vymenil za BBB BHT-96 ScrewOn. Rovnako tak časom aj omotávku...
Lanko na prehadzovačke také dlhé, že mi to pri jazde a radení dooškieralo samotnú hadzku... Opäť je to len vizuálna stránka, no nepoteší na novom bicykli...
Toto sú len vizuálne nedostatky, ktoré sa dajú jednoducho odstrániť a ideme ďalej...

Horšie to bolo so samotným bicyklom v prevádzke ešte pred všetkými úpravami a doladením po prvých odjazdených kilometroch...
Musím žiaľ konštatovať, že napriek tomu, že ide o najvyššiu radu gravelu od CTM, príprava z "fabriky" je katastrofálna.
Suchá sedlovka, suchý predstavec, suché snáď všetko, čo si viete predstaviť... a hlavne (a to som nečakal) kompletne suché "hlavko" - kapitola sama o sebe...

Prvých cca 100-150km problémy ešte nebadať, no pribúdajúcimi km sa začína ozývať pohon, pukanie, vŕzganie a všetko, čo pri jazde počuť nechcete.
Všetko odstrániteľné veci a tak som sa pustil do servisu. Vymenil som stred za Shimano Ultegra SM-BBR60, doladil a namazal čo bolo treba. Všetky kontaktné plochy ako aj závitové spoje... Na čo som ale nemyslel, teda ani mi nenapadlo, že mám rozobrať a skontrolovať hlavové zloženie...

Keďže praskanie a "vrčanie" pri šliapaní neprestávalo, a ja som si už nevedel rady, bicykel som odniesol chalanom do MTBikeru na kontrolu.
Skrátim to... po 3 servisoch (vrátane garančky) a 100€ účte, chalani nakoniec našli príčinu a to už spomenuté hlavové zloženie... Pre mňa nepochopiteľné, že takáto časť bicykla zostala pri skladaní neošetrená... Veľká škoda a nedostatok, ktorý ma dodatočne stál nemálo peňazí. Aj chalani zo servisu krútili hlavami... Suché hlavko spôsobovalo prenášanie všetkých tých pazvukov a praskaní cez rám do pohonu a celý čas sme hľadali problém niekde "dole".
Akokoľvek, vybavené a pre mňa dobrá servisná skúsenosť, že aj nový bicykel má takéto nedostatky...

Spočítané a podtrhnuté...

Ja mám tento bicykel veľmi rád!
Geometria mi vyhovuje a na bicykli sa cítim veľmi dobre. Obzvlášť, po bikefittingu, ktorý viedol Matej z BA predajne, za čo veľmi pekne ďakujem. Bola to výborná skúsenosť, cenné rady a mnohé zaujímavé informácie.

Po odladení všetkých nedostatkov je Koyuk výborný parťák tak na poľných a lesných cestách ako aj na asfalte, kde som s ním zatiaľ najazdil najviac.
Komponenty sú naozaj kvalitné a vo vyšších radách, čo sa verím prejaví aj na životnosti (samozrejme pri pravidelnej údržbe).
Napriek tomu, že nejde o prémiovú značku ani model, je to určite výborný vstup do sveta gravelu a čiastočne cestnej cyklistiky...

Celkové moje hodnotenie 3/5 je hlavne z dôvodu "pripravenosti" bicykla a nedotiahnutých detailov, ktoré sú naozaj vecou lepšieho prístupu a ochoty dať zákazníkovi to najlepšie, čo v danom segmente CTM ponúka.

Verím, že si bude CTM dávať lepší pozor na to, ako ich bicykle budú odchádzať k zákazníkovi.

Všetkým veľa šťastných kilometrov!

After reading the reviews from the guys above, I immediately disassembled the headset, removed the fork and lubricated everything thoroughly. There really wasn't any grease. I checked all the screws, adjusted the seat, the rams and started riding. It's my first gravel bike, so I'm gathering experience. So far I've only ridden MTBs. Let me start by saying that I don't regret the purchase in any way. The bike is reliable, well equipped, the GRX kit works as it should, the Fizik seat has a good shape and is comfortable, the FSA rams 440 mm are sufficient. I just replaced the plastic ones with Tufo Thundero 44HD. I'll change the wrap on the rams. There's only a 1mm thick base. I sealed the holes in the frame with tape. I've ridden more than 1000km on the bike. I've tested its limits both off-road and on the road. Its characteristic feature could be primarily stability and comfortable seating. I would call it a gravel bike. I am satisfied with it and it suits my riding style. I have a size 580. I am 186cm tall.

Po precitaní recenzii od chalanov vyssie, som hned rozobral hlavove zlozenie, vybral vidlicu a vsetko dokladne namazal. Naozaj tam nebolo ziadnej vazeliny. Skontroloval som vsetky skrutky, nastavil sedadlo, barany a zacal jazdit. Je to moj prvy gravel, takze zbieram skusenosti. Doteraz som jazdil len na MTB. Hned na uvod napisem, ze kupu v ziadnom pripade nelutujem. Bicykel je spolahlivy, dobre vybaveny, GRX sada funguje ako ma, sedadlo Fizik ma dobry tvar a je pohodlne, FSA barany 440 mm postacujuce. Vymenil som akurat plaste za Tufo Thundero 44HD. Omotavku na baranoch budem menit. Je tam len taka 1mm hruba zakladna. Diery v rame som zalepil paskou. Na bicykli som najazdil viac ako 1000km. Skusal som jeho limity aj v terene aj na ceste. Jeho charakteristickou vlastnostou by mohla byt v prvom rade stabilita a pohodlny posed. Nazval by som ho takym cykloturistickym gravelom. Som s nim spokojny a na moje jazdenie mi vyhovuje. Mam velkost 580. Meriam 186cm.

Potrebné dať vazelinu okrem kolies, všade. Pred týmto Kellys Soot50, ale CTM je o dosť pohodovejši..pre mňa

Variant CTM KOYUK 3.0 28 bicykel, matná čierna/lesklá čierna

First of all, I have to say that I am a fan of the CTM brand. I bought a road bike from them 18 years ago. I switched to the Koyuk from the Cube brand.

On paper, the bike looks very good. However, when I bought it, I was unpleasantly surprised by the details. For example, in the frame you can find holes for the Bowden cables that were left uncovered. However, the plugs cost a few cents in China and it would look different right away.

The handlebar cap also looks bad. The whole bike is black and they put a silver cap in the handlebars. Another thing is that the wrap is finished with ordinary insulating plumber's tape (am I wrong?).

These are details that he really regrets, since they are a matter of a few cents and spoil the resulting milking.

I evaluate the bike after about 1200 kilometers. The bike is nice, dynamic, handles well and I also consider the single chainring a plus. I was worried about it, but I wouldn't change it anymore. What I will change are the tires, they are two categories lower than the Tufo Speedero.

V prvom rade musím povedať, že som fanúšikom značky CTM. Už pred 18 rokmi som si od nich kúpil cestný bicykel. Na Koyuk som prechádzal zo značky Cube.

Na papieri vyzerá bicykel veľmi dobre. Už pri zakúpení ma však nemilo prekvapili detaily. Napríklad v ráme nájdete diery po bowdenoch, ktoré zostali nezakryté. Pritom záslepky stoja v Číne pár centov a hneď by to vyzeralo inak.

Zle vyzerá aj záslepka na riadidlách. Celý bicykel je čierny a do riadidiel dajú striebornú záslepku. Ďalšia vec je tá, že omotovka je zakončená obyčajnou izolačnou inštalatérkou páskou (či sa mýlim?).

To sú detaily, ktoré má strašne mrzia, keďže ide o pár centovú záležitosť a kazia výsledný doje.

Bicykel hodnotím po cca 1200 kilometroch. Bicykel je fajn, dynamický, dobre sa ovláda a za plus beriem aj jednoprevodník, Obával som sa ho, ale už by som nemenil. Čo budem meniť sú plášte, oproti Tufo Speedero sú dve kategórie nižšie.

To begin with, I must say that I am a fan of the CTM brand. I have a 13-year-old bike from them, the CTM elite plus, a cross bike, and I am still very satisfied with it, back then everything was still done honestly, the complete deore set and it works as it should. That is why the choice was clear to me and I went for the CTM brand.
I chose the top gravel bike, the Koyuk 3, I saved up for it and gave myself a great gift for my 40th birthday ?. I really liked it, although I also don't understand the holes in the frame and the ends on the bars, which my 7-year-old son told me were rearview mirrors (really, and he likes them - I don't). I fell in love with the bike from the first moment and I take care of it like a child. I bought protective films, I also sealed all the holes in the frame.
From the moment I started riding (I've ridden over 500 km in 3 months now) I expected it to be a big difference in speed. BUT IT WASN'T. My fault, I had underinflated inner tubes, about 1.4 bar, I only found out after the warranty, when I managed to cut the inner tube on the curb. When I put the new one on, I also checked the other wheel and it was 1.4 bar. I thought that I didn't have to check anything after the warranty (I was wrong). I inflated the inner tubes, cleaned them, lubricated the bike and the Strava app started showing new PRs (personal records). Wow, great.
Also, before the warranty, my front brake was not braking well, it vibrated and here and there I could hear a crackling sound from the front wheel. After the warranty, the brake continued to vibrate, but I took it as something that must have simply been worn out – it braked ok, and also that the frame must have simply settled down since it was cracking a little from the beginning. I never had anything like that with my old bike.
After about 200 km, however, the bike started to make an unpleasant noise at regular intervals, I didn't know if it was the headset, the bottom bracket, the cranks, or what. It just seemed to me that it was coming from the front. A colleague at work (an experienced biker) advised me not to try to repair anything there, that I should take it to mtbiker under warranty.
I brought the bike to mt biker Banská Bystrica with the fact that something in the front was still cracking and the front disc was still vibrating. I came back to pick it up a week later.
To sum it up, the front disc continues to vibrate, the popping hasn't stopped (it's noticeable when going uphill under load). I expected more from Fungel for a new bike (I bought it at the end of April, it's now July), that's why I gave it 2 stars. But it rides great, it's beautiful and I'm very happy with the geometry.
However, I'm desperate because something is breaking inside and the brake is completely useless. When I brake at 50-60 km/h, I can really feel it.
So I don't know if the "comrades" made a mistake somewhere in the CTM, but since I bought it, I'm only dealing with the bike. So I bought a new bike, which was probably never new.

Na začiatok musím povedať, že som fanúšik CTM značky. Mám od nich 13 rokov starý bike, CTM elite plus, crossový ešte, a doteraz som s ním nadmieru spokojný, vtedy sa ešte poctivo robilo všetko komplet deore sada a funguje ako má. Práve preto bola pre mňa voľba jasná a išiel som po značke CTM.
Vybral som si najvyššiu radu od gravelu a to Koyuk 3, šporil som si naň a na 40ku som si urobil super darček 😊. Veľmi sa mi páčil, aj keď tiež nechápem tie diery v ráme a tie koncovky na baranoch, na ktoré mi môj 7 ročný syn povedal že to mám spätné zrkadlá (fakt, a páčia sa mu – mne nie). Od prvej chvíle som sa do bicykla zamiloval a starám sa oň ako o dieťa. Kúpil som si ochranné fólie, taktiež som zalepil všetky diery v ráme.
Od chvíle čo som začal jazdiť (momentálne za 3 mesiace mám najazdených cez 500 km) som čakal, že to bude veľký rozdiel v rýchlosti. ALE NEBOL. Moja chyba, mal som podfúknuté duše, cca 1,4 baru, to som zistil až po garančke, kedy sa mi podarilo na obrubníku seknúť dušu. Keď som nasadzoval novú skontroloval som aj druhé koleso a malo 1,4 baru. Myslel som, že po garančke nemusím nič kontrolovať (omyl). Dofúkal som duše, vyčistil, namazal bike a apllikácia strava začala vykazovať nové PR (personal records) . Wow, paráda.
Taktiež mi pred garančkou zle brzdila predná brzda, vibrovala a sem tam bolo počuť pukanie od predného kolesa. Po garančke brzda vibrovala ďalej, ale bral som to tak, že sa to musí jednoducho vyjazdiť – brzdila ok, a taktiež že rám si musí asi jednoducho sadnúť keďže od začiatku trošku pukal. Nič také som so svojím starým bicyklom nikdy neriešil.
Po ďalších cca 200 km však začal bike nepríjemne v pravidelných intervaloch pukať, už som nevedel, či to je hlavové zloženie, stredová os, kľuky, alebo čo. Len sa mi zdalo, že to ide z predu. Kolega v práci (skúsený biker) mi poradil, nech tam nič neskúšam opravovať, že to mám v rámci záruky zaniesť do mtbikeru.
Bike som doniesol do mt biker Banská Bystrica s tým, že stále puká niečo v predu a taktiež predný kotúč stále vibruje. O týždeň som prišiel poň.
Zhrniem to tak, že predný kotúč vibruje ďalej, pukanie neprestalo (pri záťaži hore kopcom je to citeľné). Čakal som od fungel nového biku viac (kupoval som koncom apríla, teraz je júl), preto som dal 2 hviezdičky. Jazdí sa mi ale na ňom super, je krásny a s geometriou som veľmi spokojný.
Som však zúfalý, že vkuse niečo puká a tá brzda je úplne na nič, keď brzdím pri 50-60 km/h tak to veru cítiť.
Čiže neviem, či v tom CTMku ,,soudruzi udelali" niekde chybu, ale ako som ho kúpil tak riešim len bike. Čiže kúpil som si nový bike, ktorý asi nebol nikdy nový.

My girlfriend rides it and she praises the geometry, it rides well for her.
The price-performance ratio is very good in my opinion.
What I would criticize are the threads for attaching the bottle cages, they are very, very high, I don't understand why, it is not possible to put a taller bottle under the seat post, while there is still a lot of space below. The same on the down tube..
Quick release wheel clamps need a bit of practice, they are weird. The seat post clamp loosens itself every time it is opened.
Otherwise a nice bike for the money

Jazdí na ňom priateľka a geometriu si pochvaľuje, jazdí sa jej dobre.
Pomer cena výkon je podľa mňa veľmi dobrý.
Čo by som vytkol sú závity pre uchytenie košíkov na fľaše, sú veľmi veľmi vysoko, nechápem prečo, pod sedlovu tyč nieje možné dať vyššiu fľašu pritom dole ostáva ešte veľa miesta. Rovnako na šikmej trubke..
Rýchlo upínaky na kolesá potrebujú trochu cviku, sú divné. Upínak na sedlovu tyč sa sám povoľuje pri každom otvorení..
Inak fajn kolo za tie peniaze
