Variant Shimano Tourney BB-UN300 68x122,5 mm LL123 zapuzdrená os štvorhran

A great replacement for the usual already built-in square compositions. It goes easily and the installation is also simple.

SK Dobry den,

ak mate priestor medzi prevodnikmi/klukou a ramom, tak mozete zvolit aj kratsie prevedenie, pre istotu dostatocnej medzery odporucame zvolit skor dlhsi variant.
