My Bridgestone MB-5 currently has a 7-speed rear wheel. I'd like to convert it to a 10-speed. Is this possible? Is it practical?

The bike is the lower end of the range (MB-6 being lowest), meaning its not worth that much and never started out as a great bike. As its steel (one redeeming feature), its possible to cold form the frame to widen the rear drop outs to take a 10speed, so technically its possible......
Practically its not worth it. The bike is old and low end. To upgrade to 10Speed you would need
- Complete Wheel (at least a new Hub and cassette)
- Chain rings
- Shifter Cables
