bolt sheared off... help!
Discussion
In a massive demonstration of 'if it aint broke dont' fix it' I managed to shear off a bottle cage bolt at the weekend.
I'm guessing it was just a crap 0.1pence bolt which had a couple of winters untouched, but the result is I now only have 1 bottle cage, and in this weather I'm running out of water!
How on earth can I remove it? The bolt is burried about 5mm into the hole in the frame (carbon frame). I'm not sure I could drill it out, and suspect I have a good chance of an expensive slip.
Any tips?

could you try and screw a bolt in on top of it to screw it through in to the tube and then let it drop out the end?I'm guessing it was just a crap 0.1pence bolt which had a couple of winters untouched, but the result is I now only have 1 bottle cage, and in this weather I'm running out of water!

I'd brim the hole with Plusgas to try and seep into the threads a bit, then drill the bolt and use an extractor.
Bear in mind that if you drill it, it MAY spin the remains of the bolt and screw it through to drop into the frame, which kind of solves your problem aside from never being able to get the bloody thing out depending on frame design. If you can get a left hand drill bit, it may possibly unscrew itself while drilling and negate needing an extractor.
If you can get it bang on central while drilling, drilling right out to the minor diameter of the frame thread and retapping to clean it out is also an option.
Don't forget some grease or anti seize on your new bolt!

New bike time I'm afraid. I'm prepared to you £50 for yours but no more as it's damaged.chrisga said:
Perfect excuse to upgrade frame/forks/wheels/groupset surely?
Indeed - one of the stoppers/ends for the brake cable outer sheared off the top tube on my road bike in March. I bodge fixed it with a continuous outer cable from lever to caliper with cable ties down the top tube. Worked fine ever since.Still bought a new bike though
