Here's my mtb. Had it for about 7 years and beat the crap out of it at least once a week. Destroyed both wheels, a couple carriers, and have gone though gearsets and chains. I do about a 20-30 mile loop from north austin to, and around town lake staying off the main streets. I'm thinking of a road bike but it seems to me I'll get a better workout on this. Clip-ons took some getting used to but worth their weight in gold.
