Hi guy, I got GT i-drive 5 and a set of nice looking RF Ride XC cranks. Could someone point me to the right direction of spindle length? I am running them 1x, upload the photo just for reference.

Hi guys, Keep running into issues with my restoration of a 1990 Alpine Stars Al-mega DX. I finally managed to remove the plastic SKF bottom bracket, that was super rough. But the corrosion on the BB has caused damage to the aluminium shell and caused the threads to become very pitted. And now...

Hi all, I do have a Merlin '93 frame and want to know which bottom bracket size I can combine with which cranks for this frame. I thought that it depends also on the frame as the chain stays may differ from frame to frame. But as the sheets I found do not list specific frame brands, I guess...

Hi all, newbie to this forum and to restoring old MTBs so I hope that’s the right place to post this question. I would like to paint the Yo Eddy I recently acquired but I am not sure I can remove the original press fit BB in a way that doesn’t damage the frame and the BB itself. Any ideas of...

I have acquired a Raleigh Royal to which I am now trying to fit suitable new parts. I found out that the BB is 71mm, 26TPI and the axle for this is 126.5mm long (stamped 5S). If I keep the BB in place it still has a 126mm axle and I'm not sure which crank would fit for the chain line to go...
