Variant Shimano GRX FC-RX810-1 HTII kľuky, 42T, 1x11

SK Prechádzal som z 3x9 na 1x11 z octalinku. Kľuky idú hladko, zatiaľ čo som skúšal tak reťaz nespadla. Sú naozaj ľahké. Za mňa túto investíciu neľutujem. Išiel by som do nich opäť.

Variant Shimano GRX FC-RX810-1 HTII kľuky, 42T, 1x11

SK Dobrý deň,

chcel by som sa spýtať, či tieto kľuky vime napasovať do rámu GT Grade Carbon Elite 2021 - šírka domčeka je 73mm, aktuálne je tam stredové zloženie FSA PF30 - viem, že ho v prípade týchto kľúk budem musieť vymeniť, len ma zaujíma, či ich tam vôbec viem dostať - tzn. aké stredové zloženie by som musel dokúpiť.

Ďakujem.

SK Dobry den, toto je ale velmi nestandardna sirka domca pre Press fit. Tazko sa to aj hlada. Kazdopadne skontrolujte si priemer osi na klukach. Ak je 24 mm tak nemusite menit stredove zlozenie. Ak je vsak os tensia, ako na niektorych FSA klukach byva 19 mm, tak potom bude potrebne hladat nieco specificke ako napr. toto: https://www.bikesportadventure.com/gb/bottom-brackets/44270-fsa-movimento-centrale-bb-pf30a-73-smn-per-telaio-cannondale-pf30a-4710243909041.html?utm_source=chatgpt.com

Avsak treba si dat pozor ci aj priemer otvoru na stredove zlozenie je rovnaky. V tomto pripade ide zrejme az o 46 mm oproti beznym 41 mm.

SK Ďakujem. Už som tieto kľuky zavrhol. Vo všetkých zdrojoch som našiel, že na 73mm rám majú krátku osku. Písal som aj na podporu Race Face kvôli tomuto stredu (https://www.raceface.com/products/pf30-24mm?srsltid=AfmBOorw1s36ZSTksXwbxEF34Oh1JysrxwVYKEBglQHA5a6QiBTiAXid&variant=31976320761938) ktorý máte aj tu na MTBikeri a vyzeral, že by mohol byť, ale odpoveď bola:

"That BB would fit the frame, but it does have about 20mm of external bearings and cups, so that is more of a MTB width. The minimum internal width of that setup on a 73mm shell is about 95mm."

A 95mm je priveľa, ľavá kľuka by nebola na doraz, takže som zmenil taktiku a kľuky pôjdu Sram Rival 1x12 DUB Wide (píšem pre prípad, že niekto rieši podobný problém).

SK Dobrý deň. Prosím o radu. Mám kľuky FSA Gossamer Pro so stredom BB386EVO. V prípade výmeny kľúk za GRX RX810 bude nutné vymeniť aj stred? Je možné u vás zakúpiť tieto kľuky s 38T prevodníkom? Ďakujem, Ondrej.
