If so, have you ever had a problem with your rear triangle linkage? I have a GF Sugar 4+ and the rear triangle linkage broke (a join just gave out). I returned the bike to my bike shop and they've changed the part *free of charge*. Cool service these guys offers. About your bike, I suppose you came back home with your bike on your back walking...

My rear derailleur broke, so I rigged for singlespeed so I could get back home, with the chain on the granny gear ring. With no way to adjust chain tension, the chain was slack. I took it easy at first, but things were holding so I picked up the speed. The chain jumped up to a larger cog, which made the chain tension *WAY* too tight, completely warping my small chainring before stripping the stack bolts clean out. It completely ruined by small chainring and the driveside crank arm. I bent a ring last year.

I have bent chainrings back into shape with an adjustable wrench before, but this one looks like it needs to go into the vice. Why don’t you post a new picture after you fix it? I am curious to se how it turns out. Ouch, that’s quite a bend. I have bent chainrings back into shape with an adjustable wrench before, but this one looks like it needs to go into the vice.

Or 8. Or even 7 apparently given the discussion around here. Time to replace that large ring with a bash guard and go 2X9. Or 8. Or even 7 apparently given the discussion around here.

We were riding some singletrack at a fairly desent clip and rode over this little log/root section. Not thinking that the angle of the tandem wouldn't clear this like it does on my regular bike, I didn't adjust at all. We hit a root with a full head of steam and something had to give. I was ejected but my wife, like a good trooper, went down with the ship, having her weight and the weight of the tandem scrape her shin basically off on a slickrock type outcrop. The front timing ring of the tandem was folded over about like yours. I thought we'd have to push the tandem out and sell it since I knew she'd never get back on. To my suprise, she told me to fix that thing so we can ride out. Out comes my Cool Tool, I clamp the adjustable wrench on the ring and straighten it out. We finished the ride and rode that timing ring for quite a while before replacing it. We (my wife and I) bent a chainring on our C’dale mountain tandem like that once.
