Excellent material, I first ordered shimano BBUN26 but shorter size, but compared to Shimano and Force, Force is much better quality and better bearing performance, I definitely recommend it. Mounted on Merida Matts 40D2012. Fits perfectly
Range 122.5 after 200 km no problem.

SK Veľmi slušná kvalita spracovania. Misky sú hliníkové (telo oceľové). Oproti iným monoblokom sú misky utesnené oveľa lepšie, navyše je vnich aj dodatočné gumené tesnenie, čiže samotné ložiská sú oveľa lepšie chránené od prachu aj vody.

Much better quality than shimano, beautifully smooth operation. Pay attention to the correct width, Shimano uses common widths marked LL123 (123 mm) or D-NL (122.5). I used this as a replacement for the LL123 and it works flawlessly.

It works well, but I'll probably switch to Hollowtech II, because with the square ones I have a problem with pulling the cranks, namely with screwing in the puller and usually the thread on the crank is broken.

Hello. On the old bottom bracket, which is 126 mm long, the side facing the triple chainring bottom bracket was longer than the bearing. I would like to order a new encapsulated Force BSA bottom bracket. The side facing the triple chainring bottom bracket is also longer. It is not visible in the picture. I can't read it anywhere. Thank you.

SK Dobrý deň,

podstatný je rozmer osky - teda jej celková dĺžka, ktorá sa volí podľa rámu bicykla, príp. podľa pôvodnej osky a taktiež šírka domčeka. Táto oska je určená pre domček 68mm, pokiaľ máte na bicykli práve tento, môžete osku použiť.

SK Dobrý deň,

áno, ak Vám sadne rozmer osky a šírka domčeka, tak samozrejme tento stred môžete použiť, jedná sa o štandardný 4-hranný model s BSA závitom ktorý pasuje na drvivú väčšinu rámov.
V prípade starších modelov, príp. cestných rámov, sa sem tam vyskytne ITA závit (na jednej strane opačný ako BSA), to je jediné čo si musíte skontrolovať, inak to pri voľbe správneho rozmeru sadne určite.

V prípade akýchkoľvek ďalších otázok nás neváhajte kontaktovať.

Prajem pekný deň.
