I do not recommend it, after about 500 km, popping sounds began to appear. Tightening or lubricating did not help. There is a lot of play between the red plastic rings and the Shimano axle.

SK Dobrý deň,

aký ročník je Váš rám? OSBB sa vyznačoval šírkou 61 mm, nie 68 ako spomínate Vy. OSBB 61 mm stredy mali Specialized rámy r. 2011-2014. Bolo to trošku nešťastné riešenie, kvôli prítomnosti plastových spacerov sa často objavovali pukavé zvuky..

Žiaľ pre použite klasického BB30 stredu budete potrebovať adaptér - https://www.mtbiker.sk/shop/praxis-osbb-vlozka-stredoveho-slozeni.html?preview - tento diel je žiaľ pomerne neštandardný a je aktuálne dlhodobo nedostupný.

SK Zdravim, je to 2015 myslim, pretoze uz ma nalisovanu hlinikovu vlozku v domceku a rozmer je teda 68/42 mm. Momentalne tam mam klasicke loziska BB30 ale chcem ich vymenit za toto zlozenie pretoze tam idu osadit Shimano kluky s priemerom osky 24 mm (myslim…) a rovno chcem teda vymenit cely stred preto sa pytam ci by mi tento na ten ram a kluky sedel. Zle som sa vyjadril nie je to OSBB so sirkou 61mm. Vdaka
