Catastrophe! Training for our upcoming ride, I had put two gallons of water on the front rack as if low riders, and had four gallons on the back end. We were 3.3 miles from home, coasting a gentle downhill to a stop sign. I down shifted the front end to granny and downshifted the back end to first and WHAM!!! Chainsucked the rear end.
Squeeze drops her load (28 pounds of water) and cycles home to get the VW Bulli for vehicle recovery.
Had to take a chain tool and "cut" the wheel out of the rear end mess. Wheel is at the bike shop. No spokes broken. Don't know if the freewheel survived. At this stage, I don't know if the derailleur caused and/or was destroyed by the event. I just know that my BD just gutted itself a few weeks before its first grand tour ride.
I am prepping the "grocery getter" for a 185 mile tour. Now, I'm scared to take the BD 185 miles. Will it do this again?
Do we know a risk and frequency for chainsucking the rear end of a BD?
I need some input as to whether or not to trust and take the BD or to use my (38,000 mile/1984) grand touring bike.
