    You've got my sympathy ... 3rd ride on my Spot and the crank arm came off. Luckily I was riding flat pavement on the way to the trail head, but not so lucky because I couldn't find the bolt that fell out and let the arm come loose.

    Yeah I lost my bolt too. I thought my pedal was messing up about 8-9 miles into the ride, then I looked down and was like "oh crap". My multitool didn't have a big enough allen so I couldn't tighten, I got out off the trail and rode on the road with just my right leg and it fell off going uphill, haha.

    looks somewhat familiar....



    original bontrager left arm loosenned itself up and came off. bolt dissappeared in the mud. last set of isis cranks i've owned, as every previous one had nearly done the same.

    We had a guy with a loose crank arm bolt - 10mm socket head. We came up with three 5mm allen wrenches between the lot of us and were able to tighten it.

    Of course, I know this will never happen to you again.

    Good luck ever getting that crankarm to stay on again.

    It was probably creaking, because it was loose... you should always do a preflight checklist, make sure stuff is tight every now and then...

    if it's square taper, and you mushroomed the crank a little, it can be fixed. i had done it once or twice back when i ran square taper, and my solution, which worked and was permanent, was to roll up little pieces of aluminum foil(like, from your kitchen), line em up in the bore, and tighten the crank down. it effectively 'cold forges' them into it.

    But oh so unlucky as if it's square taper, it's trashed.

    Nope, external bearing

    Will apply plenty of Loctite and torque properly when the replacement bolt shows up (hoping for today or tomorrow). It's my own damn fault (h/t Jimmy Buffett) since I didn't check it when I got the bike.
