This is my first post on RBR, but I usually post on MTBR. I just built up a Raleigh Capri (circe ????) frame so it'll be more convenient for me to ride on days when I can't make it out to my local mountain biking spots. And I've found that road riding is actually very enjoyable.

That aside, I need to replace the rear-end of my drivetrain and I'd like to ditch the freewheel. I've currently got a 6er on the back in the form of a touring-style freewheel. I want to upgrade to a new hub/hyperglide and install a new cassette. I'm new to road biking, so I don't know exactly what to be aware of when doing this switch. Can anyone give me pointers on things to look out for? Are newer hubs generally too wide for vintage frames?

Also, I've got SR Suntour downtube shifters. I know they are not the best and I will upgrade these eventually, but is there enough throw on these paddle shifters to shift through say 8 cogs?

Any help would be greatly appreciated.

You will need to spread the rear triangle spacing from 120mm to 135mm spacing (most likely - maybe 130mm). A good LBS could do this for you.

The shifters might work, but they might not. Give them a try. If they don't work, find an 8-speed index shifter. You might also need a newish Shimano derailleur.

Why not just stick with 6-speeds on a freewheel? You can still get wheels set up like this cheap (check www.nashbar.com).

Good luck!
