SK Mám Ultegru R8000, 52/36T, 175 mm a chcel by som vyskušat kratšie kľuky 170, 165 mm. Som vysoký 183 cm. Dajú sa samostatne objednať a čo by stáli? A doporučujeme mi to a akej dĺžky?

SK Dobrý deň, starší model FC-R8000 už dostupný žiaľ nie je.
Pre 2x11 setupy sú z kratších kľúk dostupné v 52/36T setupe napr.: https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/cestne-a-gravel/sram-rival-22-gxp-kluky-2x11-52-36t-p25816.html alebo https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/cestne-a-gravel/sram-red-gxp-carbon-kluky-170-mm52-36t-2x11-p301616.html (bude potrebná aj výmena stredového zloženia za GXP model).
Dĺžka kľúk je individuálnou záležitosťou - pred samotnou výmenou môže príp. pomôcť aj bikefitting - kľúčovú úlohu zohrajú aj parametre Vašej postavy, jazdecký štýl a posed na bicykli: https://www.mtbiker.sk/shop/informacie/bikefitting.html.
