Trying to get a little more info on this - can someone tell me if the bolt takes a 3mm or 4mm hexallen key? Don't want it if it's 3mm, likelihood of it stripping seems higher. Thanks.
I've never had a Thomson bolt go bad, but everything has a failure point. I have one for just such a situation, as this will happen when you least expect it. I try to remember to put one in my saddle bag for long or out-of-state rides... just in case. Otherwise, it's in the tool box.
