All new drive train!
Posted On Friday, November 14, 2008 at at 11:29 AM by MTB ManLast post, I mentioned losing my crank on a ride. Well the square hole in it was rounded so it needed to be replaced and you can't just replace one crank, you have to replace both and the other crank is part of the front gears so it's a crankset that has to be replaced and the new crankset wouldn't work with the old bottom bracket plus it was worn out anyway so that had to be replaced and it turned out that the chain was shot and that in turn had worn out the gears in the rear so the cogs had to be replaced .... <take breath here>
Whew.
Cost about $170. More than I paid for the bike.
I had Matt at Mad Dog Bicycles get me a compact crankset which means a smaller small chainring for easier climbing.
The crankset is a Shimano Sora and it's pretty cool and here it is:
I took it out this morning for a short test run and it shifts very smoothly.
Matt did a great job. Everything works perfectly. He even remounted my cadence sensor on the new crank and adjusted it so I didn't have to do anything this morning.
The rear cog set is a Shimano MF-TZ20.
I didn't test it on any big hills 'cause I really needed a break today. I've been overdoing it lately and I'd like to take a nice long ride this weekend.
I'll have to see what Charles is doing.

I also replaced the 6 broken spokes on the ROSS MTB rear wheel.
I bought 10 spokes from Matt at a buck apiece. They are black instead of silver but what do I care?
I'm thrilled that I did this repair myself. Wasn't too bad. I had the spoke wrench and the thing to remove the cogs. I'm not too concerned about absolute truing of the wheel. As long as it doesn't rub the brake pads and all the spokes are tight, I'm fine. I spent a little time degreasing the cogs since I had it off. There is one broken tooth on it but it still works fine. I wouldn't know it but to look at it.
