A faithful and useful helper for everyone who works with HTII guys. Heaven and bagpipes compared to plastic versions! There is no chance that the hex key will scratch something and then it will become unusable.

Verny a uzitocny pomocnik pre kazdeho, kto pracuje s HTII klukami. Nebe a dudy v porovnani s plastovymi verziami! Tu niet sance, ze by hex-kluc nieco zodral a stalo sa to potom nepouzitelnym.

you can get by without this tool, but...actually, I don't deal with loosening and tightening anymore, and above all, I don't damage the plastic with modified metal ?

zaobídeš sa bez bez tohto naradia ale ...vlastne už neriešim povoľovanie a doťahovanie a hlavne nepoškodím plast upraveným plechom😊

SK Hoci viem, že uťahovací moment matice je veľmi malý, predsa som rád, že je kľúč oceľový a za zvyšok života ho nezoderiem.

For me, it's a perfect tool and since it's metal, it'll last forever in my use, just don't lose the key.

za mňa perfektný nástroj a keďže je kovový tak pri mojom použití naveky super kľúč len nestratiť

Good evening,
I ordered this metal wrench for the left crank lock nut from you and it has already arrived, but it doesn't fit my left crank. How is that possible, are there other sizes? I think I would need a slightly smaller center rosette. Is the plastic version of this wrench exactly the same as this metal version?
My cranks are SHIMANO SLX FC-M7000-11 (170mm). Is there any other way I can remove the lock nut?

Dobrý večer,
objednal som si u vás a už mi aj prišiel tento kovový kľúč na poistnú maticu ľavej kľuky, no nepasuje na moju ľavú kľuku. Ako je to možné, sú aj iné rozmery? Myslím, že ja by som potreboval trošku menšiu tú stredovú ružicu. Tá plastová verzia tohto kľúča je úplne identická ako táto kovová verzia?
Moje kľuky sú SHIMANO SLX FC-M7000-11 (170mm). Je nejaký iný spôsob ako môžem odmontovať tú poistnú maticu?
