Wow... I didn't knew all the expense needed for that project.

The rear axle is 126mm and it has a 5-speed freewhel, 14-28t. The 7 speed ones I can get here are also 14-28, so there's no gearing improvement beyond the index shifting.

I'd like to change the brake levers since they are busted. Now that STI brifters are not an option, What do you think about these other ones? And How can I know if they could work with the old center-pull brakes? Thanks.
