She was old. The bike, not the deer. Or Liz. She was an old Orange X2 full suspension that had seen better days. Every bump made her pivot groan and squeak. Bike arthritis.
Grinding uphill, I shifted into the lowest gear and came to a clattering halt. The derallieur had travelled too far and tangled with the spokes, bending itself off the bike.
A field repair worked enough to get home, but it looked like a new mech was needed. Too expensive for an old bike. So her stripped down frame is lying behind the shed. The wheels / forks / suspension I might be able to sell on ebay.
Now I need a new bike to abuse.
