I work in the Quality Assurance Department at an Engineering firm here in Baltimore, which means I get to use a lot of really nifty tools and precision measuring equipment. We just got this beauty today and I've been using it all morning. It's a digital torque wrench. It's awesome. I'd love to have one of these for working on my bikes. Who really knows how much torque you're putting on those little chain ring bolts? What about your pedals? How much is too much? I have a feeling I'm over-torquing everything. It's nice, it's fun, it's $385.00.
