All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.

Our bike shipment is as follows:
  1. The bicycle is taken out of the manufacturer's box
  2. The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
  3. The bicycle is carefully packaged back into a box and shipped
  4. If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
  5. If you order a bicycle via courier to your home address, the following must be done at home:
    1. Take the bike out of the box and carefully remove safety material and foils
    2. Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
    3. Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
    4. Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
    5. Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
    6. Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
    7. Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
    8. Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
    9. Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.

SK Bral som na svojich 176cm L verziu, ale je to dosť veľké. Sedlo posunuté max dopredu a mám to nie celkom pohodlne, ale uvidí sa ešte - mal by to vyriešiť kratší predstavec. Pri podobnej výške na rozhraní M/L radšej vyskúšať na predajni a rozhodnúť sa na mieste.

Za mňa nasledovné zhodnotenie po necelých 100 km - mám to na cesty, ľahký trail, dal by som 9/10 pre tento účel, ale určite to má na viac, než len takého jednoduché používanie.

+ veľmi dobrý pomer cena/výkon (2099 EUR)
+ vo výbave teleskopická sedlovka
+ dobre zvolená výbava SLX, len reťaz je o radu nižšia, ale má už rýchlospojku - po zodraní volím pravdepodobne Shimano M8100 12rýchl.
+ vzhľadom na karbonový rám je to celé ľahké
+ brzdy a plášte na moje používanie úplne vyhovujú
+ široké riadidlá v základe
- sedlo len priemerné

Nenašiel som zadné svetlo ešte aké by som chcel, asi lepšie pod sedadlo niečo, resp. na šírku ako je tam dočasné teraz.

Pozor na merač kadencie - mám od Garminu a je dosť široký - ak je umiestnený blízko pedálu na kľuke smerom k rámu tak tam ostane veľmi málo miesta medzi ním a trubkou k zadnému stredu. Mne sa kus posunul a všimol som si až keď drhol o rám ... prelepil som to miesto ochrannou fóliou do budúcna.

SK Doplním sám seba - po čase som vymenil pôvodný predstavec (80mm) za kratší (40mm) a podstatne lepšie sa mi na tom sedí a ovláda. V popise je, že riadidlá majú 31.8mm, ale u mňa to bolo 35mm, tak si to radšej zmerajte pri výmene.

Podarilo sa mi tom už 2x spadnúť (raz pád na pravý bok a raz prelet cez riadidlá a bike pleskol riadlami a sedalom o zem) a okrem ohnutej pätky prehadzovača pri kompletnom rozobraní biku chalani nenašli žiadny problém, vyzerá, že rám je dobre navhrnutý a niečo znesie.

Chvíľu som mal na zadnej stavbe lepku ako ochranu pred nárazmi reťaze, ale tá trubka má členitý tvar a vrátil som tam klasiku na suchý zips.

SK kúpiš si bajk s modernou geometriou trochu prispôsopbenou na trail a jazdíš na tom cesty.... rozmýšľal si najprv pred kúpou trochu ? Ty by si si mal kúpiť gravel a dať na to odpruženú vidlicu keď nechceš aby ťa vytriaslo. Alebo nejaký čistý XC horský bajk nie toto ladené kusok do trailu preto sa ti na tom blbo sedí a ete keď si si kúpil väčšší dlhší lebo si si myslel že sa ti na tom bude lepšie krútiť a bude to mať väčršiu zotvračnosť. Presne keď som kupoval tento bajk som mal dilemu či M alebo L a chvalabohu mtbiker bol ochotný a poskladal mi obidva, ktoré som si následne mohol skúšať za predajňou v Hrádku. (Mám 183 cm a tiež mám sedlovku úplne vpredu a myslím si že mi je s najkratším predsatvcom úplne super ten bajk. Cítim sa na ňom parádne či už pri šliapaní alebo na traili) Neobmedzený čas som sa tam mohol voziť a skúšať si. Dokonca so sm irovno od nich vypýtal vymeniť predstavec za kratší. Takúto službu nedostanete hocikde. Je to veľká výhoda.

SK No a ktory si si nakoniec vybral? Mam takisto 183 cm a uz 4 roky jazdim tento bike v L velkosti. Predstavec (povodny) som este posunul najnizsie ako sa len da. V strmych kopcoch by som bral este aj dlhsi posed. Ale vzdy je to kompromis.

SK Dobry den,

idealne je si zmerat dlzku povodnych spic.

Pripadne je mozne pouzit niektoru z online kalkulaciek, napr. priamo od Sapimu - https://www.sapim.be/spoke-calculator? (podla fabrickych udajov o nabojoch a rafiku by pri 28H setupe a 3-nasobnom krizeni mali sadnut 298-300 mm spice.
Prip. ak si budete kolesa nechavat prepliest priamo u nas (https://www.mtbiker.sk/shop/informacie/servis.html), tak staci objednat typ spic ake pozadujete a dlzku si uz dorataju priamo kolegovia v servise podla dodanych komponentov.

SK Dobry den prajem,

ospravedlnujem sa za neskorsiu odpoved, notifikacia o Vasej odpovedi sa nam zial "stratila" v systeme

Je pre Vas este problem s dlzkou spic aktualny? Ak ano, tak to teroeticky vieme zmerat - bicykel nie je sice priamo vystaveny, je zabaleny v skatuli, ale je mozne prip. kolesa odbalit a aspon orientacne skusit premerat.

CS Dobry den,

to zalezi na Vasej vyske/dlzke noh - aj teleskopicku sedlovku je mozne polohovat, nemusi byt zasunuta v rame nadoraz, ale vzdy sa jej pozicia upravuje podla aktualnej vysky jazdca.

Samozrejme, istotou bude zvolit 400 mm variant pevnej sedlovky, ktory poskytne najvacsi rozsah nastavenia vysky sedla.
