Not exactly a frame, but I picked up a bargain pair of handlebars yesterday. Went to fit them and realised why they were so cheap...
Anyone have any ideas how to solve this issue? I've tried boiling water to soften them a bit, fixing them to bike and putting all my weight through one side (wow they're strong) but no luck so far. Not got access to a vice but think vice and big bar for leverage would do the trick? Thanks!

Surgery is probably going to be the best answer for that, just lose a bit of length from the appropriate arm and you'll be golden.
I can't really judge the scale, but if it's only up to a third of an inch or so you'll probably get away with the quick and dirty option of having it taken off your fingertips.
If it's any longer than that though, it's just the same principle as shortening the sleeves of a jacket and you're much better having your arms taken in from the shoulders - more work, but the final result really is worth the extra effort.

Any thoughts on repairability of this?
Recently picked up this frame and didn't notice this crack below the seat binder, which I think has grown a bit from the few rides I've had.In touch with a local framebuilder in Sheffield who said he can try to fill it with braze, but might need a full seat tube replacement if this doesn't work.
Anyone had similar cracks/repairs?
Any idea if this will work?Edit: Frame is 631 so pretty thin

I'd start by getting the right sized seatpost.
Brazing over the crack might hold it for a while but I doubt it'll stop there. -

Yeah pretty sure I've got the right one in there now, as the original was too short so swapped for a 27.2 - will defo double check this when I go, cheers.

I imagine you'd better off tig welding from a strength perspective. Very much not an expert, though.

New frame arrived but has taken a knock during transport. The bottom of the headtube is bent inwards and it's impossible to get the bottom bearing in. Taken to 2 different LBSs and they both thought it might be possible to bend back and be OK (but didn't offer their services to do it). I was thinking of using a piece of wood shaped the correct internal diameter and tapping it back with a hammer? It's alu. What are people's thoughts on this one?
Seller is being OK about it - but wondering if there is a solution to get it on the road rather than give up and send back.

It will be difficult reshaping head tube enough to let the bearings turn freely. Even if you mostly get it right, you are highly likely to have a draggy bearing that wears prematurely. For a headset bearing, this might be acceptable. They don’t typically wear out, instead dying by corrosion, contamination and brinelling.
If it was a steel head tube, you could bash away at it until you thought it was good enough and likely have enough meat on the head tube to cut the bearing seat round again. Aluminium, not so much.
Cracking of the head tube bearing seat while riding afterwards, you could possibly ride to a stop but the bearing might jam. That would put you on the ground instantly.
Your choice to try to fix it, I wouldn’t.
Noticed this on ride in this morning - it’s a cotic escapade so fairly standard cromoly - nothing super light
How worried should I be ?
