I'm not too familiar with the octalink or Q factor cranks... I'll have to pick some up. In the meantime I would post something in the forums to see if others have any suggestions.

I have a 2008 raleigh mohave 8.0 with a octalink crankset. I would like to upgrade to a better one. I’ve heard different stories about Q factor and you name it. Could you suggest a logical upgrade?

thx

I like your site. Videos are to the point and make sense. I have been my own mechanic for years. Its nice to be able to find the answers to any problem I am not 100% positive of. Very nice.

One thing I experienced is when I used that Park tool BBT-22, the splines on the drive side don’t go very far into the cartridge. I tried using a socket wrench as well and I had to securely hold the BBT-2 against the cartridge while turning my wrench. Hopefully I tightened it enough.

Thanks for the video Alex – wish I’d watched it before installing my bb; I overtightened and cracked the (plastic) lockring, thinking it had to be tightened until no thread was visible

If only all bottom bracket lockrings came off that easy!!!!!!!! Any tips for ones that won’t budge?

Thank you for making this video. After watching it a few times, I was able to remove and inspect and reinstall my BB. and it is working fine now. No more clicking when I ride.

Bottom bracket sizing is tricky. Sheldon Brown’s website has a comprehensive sizing database here:

Or you could take your bike down to the local shop for sizing. That would probably be best, as they can better assess not only the bb shell size in your frame, but also the correct spindle length you will need (depending on the type of crank arms you have).

I have purchased a frame without a cartridge bottom braket.
How do I measure the whole so I can purchase the correct cartridge??
tks
