- Has any rounded (ish) their BB, and succesfully removed it DIY?
Not sure about “rounded” but I had one where the entire external cup sheared off leaving the threaded shell inside. Cut it out with a Dremmel – cut diagnol across the threads of the shell against the threads of the frame. Got it out OK and the new one sent in fine.Posted 3 years ago
I used bb removal tool.. This:
Have no problem removing an uberbike ht2 BB in other bike. Less succesful in GXP BB..
Actually just fitted BB last wednesday all kosher using parktool grease then hand to fully screw it in then tools to tighten it.. I ride in the thursday.. And wanting to removed it the friday and this happened 😐
Thanks, for letting me know that bearings can easily be whacked out., hopefully that would lessen the stress off the thread.. Then drill.. I cant sourced out a strap thingy without buying one.. Stillson wrench quite expensive 😛 and I dont think I will have enough leverage using molegrips .. Thanks all for the time. Somehow gave me an idea to DIYPosted 3 years ago
Pipe wrench/stilsons will have that out quick smart.
Strap wrench is a waste of time as they cannot transfer a decent torque to that, its mostly for spinning things up as oppose to tightening and loosening
The bearings are under the area you have rounded not the thread , i would leave them in so they give the thin material some strength when your torquing on it, id also say that drilling through it isnt a great idea.Posted 3 years agosinglespeedstuSubscriber
I’d start off by using a better bb tool.
Then get some threaded bar or a wheel qr and clamp it on nice and tight through the bb.Posted 3 years ago
A pound to a pinch of shit it’ll come out then. 🙂
Is this enough? Or have to get a bigger one?Posted 3 years agob rMember

All kosher, since when were molgrips ‘kosher’?
Rather than now damage your frame through more cackhandedness, pay the LBS to get it off and buy a proper BB tool, a new BB and search for a video that shows you how to do it.Posted 3 years ago

I once had a very stuck bb where I had to whack the bearing out, then very carefully saw through what was left of the BB inside the frame and gently prise it out. It worked but took a very long time :(. I’d be tempted to see if the bike shop had a better fitting BB tool as it does look from the photo as there is still quite a lot of ‘teeth’ there
The tool you linked to is open ended which means that if it isn’t well made there is plenty of scope for it to widen enough to slip over the teeth rather than grip when things get toughPosted 3 years agogravity-slaveMember
Where are you? Someone might have a big set of Stillons you can borrow. If you are in Sheffield I have some.
Otherwise, depends what tools you have and how medeival you want to get.
Hacksaw towards frame and cut 2 sides off to make flats. Put in a vice or use a big adjustable.
Through drill and screwdriver a good idea
Last resort, hacksaw blade through bb and cut as deep as you dare in 3 places then collapse the shell inwards with mole grips or screwdriver and hammer.
If you don’t have stillsons, no real neat solution and all risk damaging the frame so take it easy!Posted 3 years ago
I dont think i have cross threaded it as I screw it in just using my hand carefullytill I cant screw it in no more, its then i used the tools to tighten (which i thought is a decent tool till now).. I might get that lezyne bb tool as i need it anyway.
Thanks gravity salve .. Im in the midlands..
BB says to tighten. There is an arrow.. i am undoing it the other way..untighten.. Yes removed cranks.. Removing cranks is easy enough.. No issues there.Posted 3 years ago
