Rejuvinating a vintage bike - suggestions?

[MomOnBike]

O Collective Wisdom:

I have a 1978 Raleigh Gran Prix (Walter by name) that is insisting that I Do Something for him this snowy winter, dagnabbit! So, I- - -

1) Got him out of the shed and into the basement.

2) Loosened the seatpost by means of chain lube and percussive maintenance and got the seat up to what might be a useful height - at any rate it is no longer at the absolute bottom of its range. I was surprised and pleased to find that it hadn't rusted in place. This was good. Unfortunately, the bolt holding the seat in place has gone to that great spare parts box in the sky so I need to find a replacement.

3) Ran out of inspiration. . .

So, I ask you. Now What? I'm open to suggestions.

More details; He was a 1st anniversary present from DH, he's a 10-speed, most equipment is original, and I'd like to keep as much of the original spirit of the bike as possible, if that makes sense.

Should I go with a more modern drive train? Can I do that on a budget?

My knees veto a fixie or single-speed set-up.

I'm pretty sure I'll need a new stem, as that never was quite right for me.

Or should I just clean him up and go with what I have?

What would you do?

Upgrading the drivetrain from a 10 speed may be tricky, because of the spacing between the rear dropouts. You can measure that to see what your options are, but odds are you can't do too much without respacing the frame (if you can find an ultra 6 freewheel then it will fit in the space of a 5 speed, but you may or may not really change your gear options that way depending on what you have). To completely overhaul it and make it modern requires either rebuilding the wheels with new hubs (to use a cassette) or buying a new (or used) wheelset so you can use a cassette. From there, you'd basically need all the components of a new drivetrain - if you price this out, it's not economical at all. It's possible, it's just not cheap... you'd pretty much be treating the bike as if it were only frame and starting over.

I have to say though, I'm in the middle of "updating" my own vintage bike, and so far I have swapped out the saddle and seatpost (original was too short), bars, brake levers, cables, I taped the new bars, and I have put a rear rack on it. I've decided for now to leave the drivetrain alone.. everything is as far as I can tell in pretty good shape. Of course, all of the changes I've made to mine have added up to quite a bit too.. but not as much as a modern drivetrain. However, I am learning to wrench on this bike, so the experience I'm gaining along the way is priceless.. I've been afraid to mess with too much on my trek, but for some reason I don't feel like I can really 'mess up' working on an older bike

This image is prior to swapping out the cables and putting the "final" tape on the bars, but it shows what I did with the brake levers. I used Tektro R100's (this is the women's "short reach" version of the R200) and RL720's (which i wish i could move about 1" inwards from where they are, but the clamp bulge prevents that.. something I didn't even think about when I picked that bar, but defintely something I'll consider for the future). I thought I might want a shorter stem based on the bars that were on the bike when I bought it, but my new bars had a shorter reach and shallower drop and riding on the hoods or in the drops feels pretty good to me now.



All i still want to do is put fenders on it and maybe a front basket..

Walter is lovely! I love the gentle curve of the front fork.

I know nothing about fixing up bikes, though. A good cleaning, lubing, retaping the handlebars, and a seat I really like would be my start.

Knowing pretty much nothing about bike mechanics - I'd make the bike comfortably ridable. So replace the stem, seat, new tape. Also you want to make certain the brakes actually work. Stopping is good. If the gears are in reasonably good shape - not missing or bent, then I'd stick with what you have. A bike mechanic friend managed to repair my old college bike (about the same vintage as yours) that was long neglected, suffered being stuck out in the weather a bit . As I recall, the only thing he replaced was new tubes/tires, tape, seat, and the chain. That bike carried me on my first MS-150 like a champ, then carried a friend on her first (after I declared her current beater bike unsafe at any speed).

Maybe this will give you some ideas.

I just revived my mixte (check out the mixte thread) by replacing the wheels and tires replacing the saddle with my good old brooks, replacing the brake pads and putting on fenders..
I've been riding it since my custom bike is in the shop, and although it's heavier, it's kind of fun to have just ten speeds..
