Juvela Frameset

I'm looking for any information on this Juvela frameset. It's made out of Reynolds 531 with Campagnolo dropouts and unknown lugs. Made in Switzerland. Serial #164241 on the seat stay. Campagnolo headset, seatpost, 35x1 French BB, barcons, and front/rear Nuovo Record derailers. Cinelli stem and drops.
The frame has a ding on the top tube--I tried to capture it in the final pic as best I could. Is this a cause for concern?
Can anyone pinpoint the year of manufacture? Does anyone have more info on Juvela? I have heard that sourcing French Campagnolo BBs is difficult--is this true? Does anyone have a ballpark estimate on a BB? Is anyone producing a comparable piece?

Any and all information is greatly appreciated.

I've never heard of Juvela but your frame bears a strong resemblance to Mondia frames. Perhaps made by Mondia but badged as a Juvela. Serial no. placement is exactly as Mondia did and that number, in the Mondia system, would place the date of manufacture in the early 1970's. Contact Stefan Schaefter at Speedbicycles in Switzerland. He assisted me on my Swiss Condor. His Email address is: stefan@speedbicycles.ch If anybody can help you, he's the one. Good luck and let us know the outcome.

I don't know anything about the marque, but it looks like a great find. The top tube ding is probably cosmetic. I would have expected Swiss, rather than French, BB threading.

Follow up to my previous post. Googled 'Juvela bicycles' and found two archived threads in oldroads.com. Juvela was made by Mondia.

Thanks! I'll be sure to update.

Here's a quote found at the bikelist.org archives:

Quote:
A Juvela is a Mondia without the pimpin' paint. Montrose Bike Shop near
Los Angeles sold three label-versions of the same bikes in the early 70's;
Juvelas were the plainest, Mondias a little fancier, and Paul Egli labeled
bikes were the most faded, chromed, and striped.
Here are the search results: http://search.bikelist.org/?SearchString=juvela

Where did it turn up?

The frameset was placed on Craigslist by a thrift shop employee. I decided to have a look and ended up riding back with it on my shoulder

Smart employee, and lucky you! Probably saved it from a scrap pile.

Are you anywhere near Montrose?

Yes, there appear to be a few knowledgeable bikers there, as two of them commented on the set. When I stopped by this afternoon to pick up the wheelset, one of them actually hinted that the frame may have been produced by Mondia! I popped into this thread and it appears he was right on the money.

I live in Berkeley, CA, but the shop was located in North Oakland.

only about 400 miles north of Montrose...did you remove the BB and confirm it's French (RH threads on both sides) and not Swiss (same threading but LH on the fixed cup)? Cause I agree with John E., seems likely this would have a Swiss BB. You can find new Sugino French cups (assuming the spindle is OK) on ebay, but Swiss is harder to find except from Phil Wood for their BB unit.

The BB is French. I ended up purchasing a set of thick French Campagnolo cups and a Swiss Campagnolo fixed cup before pulling it apart, so I wasn't too worried in any case. BF member jemoryl's post was the first clue in determining the fixed cup's threading:

Further digging uncovered Robert S. Broderick's meticulous Mondia restoration. He details many portions of the bike, providing a great resource for someone looking to perform their own overhaul; the bottom bracket photos and description were incredibly helpful:
Quote:
Campagnolo Nuovo Record - traditional non-cartridge adjustable type BB for 68 mm shell - stainless steel rifled spindle - square taper - pre 1978 112 mm with 5 mm drive side asymmetrical offset - caged ball bearings - 35 mm x 1 mm (25.4 TPI) French thread cups (non-drive side adjustable cup - right threading / drive side fixed cup - also right threading : caution) - two piece plastic dust sleeve - model 1046/A (68-SS-120) : early style “Black” crank bolts and washers - steel - 15 mm head - model 748 (bolts) / 749
http://www.wooljersey.com/gallery/v/...et_01.jpg.html


Stefan Schaefter was helpful with the thread ID, and I'm hopeful he'll be able to uncover more information on Juvela. I also found a thread on the bike circle forums, which confirmed French threading for Mondia (http://www.bikecircle.com/forums/tec...-swiss-bb.html ). Once I took out the adjustable cup and cleaned the shell, the threading was confirmed and I had the cup taken out and replaced.

My Swiss Campagnolo cup is marked 35x1 S, not 35x1 G; are there any differences between the two? Is anyone in need of a Swiss Campagnolo Cup? It's in excellent condition; the cup had been sitting for years in a mechanic's toolbox. I've attached a few pictures below.

I'd like to thank you all once more for helping me with this bike. If any additional information comes your way, let me know!
