Title: BXT Gravel 135 loose nut on rear triangle
Post by: majeranek on November 12, 2026, 01:02:20 PM
Hi,

I tried to unscrew the upper screws on the rear triangle on unfortunately both nuts went loose.
Is there any chance to replace them or remove? I don't need them anyway...
I was wondering if there is any hollow space near the seat tube so I can push them into frame and remove that way?

Did the insert that the bolt is threaded to come loose, so the bolt just spins around without unscrewing? If that is the case I would carefully try to hold the insert somehow if you can so you can unscrew the bolt. Use some penetrating oil for it to move easier.

Or you can saw off the bolt and carefully push the insert back if it moves or just file off the excess. Then put some epoxy or glue on top of it and yellow touch up paint if you want it to look clean.
Whatever you do be careful to not damage the carbon.

Yeah, I thought of sawing off the bolt, but I'm afraid that if I push it into frame it'll drop into the rear triangle tubes and will rattle there forever...
