trail repairs
« on: December 18, 2008, 08:20:24 PM »
Ok, here's the scenario, you're riding at Boyette on South Abyss and you lose concentration and experience an involuntary dismount. You're Ok but you trashed your derailleur. You're riding a FS bike and you have a chain tool with you. Is it possible to shorten your chain and turn your drive train into a SS to ride out?

sure, seen it done a couple of times. find a cog on the cassette that allows some slack in the chain and either lock out your rear shock or pump up the air pressure near max to lessen chain growth and possible chain breakage.

Ok, can't lock out shock and left shock pump in the truck. should you leave more slack in the chain or just ride slow and careful?

Without the derailleur, the chain will be so slack that you'd be more concerned with it coming off the cogs than snapping due to suspension movement.  Just do as Chisel mentioned and ride slow w/ constant pedaling.

I once had a suspension bolt back out and completely lodge itself across the chainrings, there was no moving that sucker, I had to use the bike as a scooter for several miles while running away from a T-storm. (This was at Flatwoods). :D

How much slack would you want to leave in the chain?

There's so much w/out a derailleur that you don't even need to consider shortening it.

So you're saying just let it hang and drag on the ground?

That's how I've done it and seen it done in the past.  You just take it easy and get out of there.

the time mine broke, it was quicker to just limp it back without shortening the chain as I was close to the trailhead.

Yea had something similar happen to me in college when I was riding a bike for transportation. I had a vacuum cleaner strapped to the top tube, don't remember why, but I do remember it came loose and lodged itself in the front wheel. Some how I managed to step over the handle bars as the bike was going down and I started running. I turned around in time to see my bike doing flips in the street.
