Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Picked up a vintage Univega; questions regarding parts/sizing.

I am not exactly sure what era it is from, more than likely early to mid 80's. It has a Suntour group, and I believe is a One Ten model. Its my size so I snatched it up for $50. I plan to paint it and trash all of the rusted parts. I need ot know what size BB, handlebars, and stem to get for it. I am assuming it will freely accept most cartridge BB's as well as 1" quill stems. This is a budget build, so advice on parts/where to buy/brand of parts is greatly appreciated.

seat post size as well.
the number will be on there somewhere near the bottom

Are these the only things you want to replace? Why not just keep the BB and learn to service it? - just a suggestion

- Impossible to tell without seeing the bike. Probably a standard English threaded BB though.
- Measure whatever stem you buy
- You can measure the inside of the steerer tube, but most likely a standard 1" quill stem
- Measure the seat tube, or better yet look at the original post for markings.

All the parts you need are on eBay, you can't go far wrong with old Suntour, SR, Sugino, Shimano 600, etc. stuff ... and I really like the old Shimano Exage brakes. The discipline is to bid low and resist the temptation to overshoot the quality you need. I don't think you'll be looking for Dura-Ace stuff for your Univega.

I have serviced several vintage bottom brackets and I absolutely know where to find the sizes. I know the steerer will accept a 1" quill. The reason I want a new BB is because everything is rusted out pretty badly. Also, I was wanting a cartridge style bb. I am guessing English threaded will work just fine in this case. I will get some pictures up when I get home in 2 weeks.

While I was attempting to remove the crank bolts, my tool and the crank arm threads got stripped badly. So now there is half of my nice Park Tools crank removal tool stuck in the threads of the rusted out crank arm threads. If I take it to a shop, they should be able to remove for me, correct?

A lot of people that post here would be able to help you out, but its a better idea to post stuff like this either in bike mechanics or maybe the classic and vintage forums.

Alright, I will just take the frame into the LBS and see what they can do to get the crank off and see about picking up a BB and seat post there. I am more than likely going to just run MTB risers and trim 3" off the ends to clean them up a bit.

On the NDS you can use deneric automotive puller.If the drive side is stripped it's dremel time.Just cut the crankarm along the bb spindle.

I guess I can try to cut the crank arms off, but I dont think any of my cutting wheels will reach down to the spindle because its such a tight fit in between the crank arm and bb shell. Do you get what I am saying here?
