Vintage Bikes With Modern Groupsets
Postby RIDER321 » Sun May 10, 2015 6:29 pm
Something I've wanted to do for a while now is convert a 12sp vintage bike that is already good with high-end tubing ect to a modern Shimano 20sp groupset. (I'm keeping all the original goodies to undo if I choose to)
So now I've aquiried a bike that weighs low 10kg/high 9kg and a modern Shimano groupset with decent carbon wheels.
After test fitting all the new modern parts it's only dropped around low to mid 9kg.
I'm yet to ride it as there is still work to be done but I would love to hear peoples experiences and input on whether the improvement was noticeable?
Have the modern hubs, gearing ect made a worthwhile improvement?
Has the ride gotten harsher or average speed increased ect..
Hope I finish my project soon to test everything for myself.
I've found similar threads with photos of some great bikes but nothing about the actual riding.

Living in a very hilly area, compact cranks with an 12-28, with the opportunity to go up to 12-30 if I need to is fantastic. In terms of weight, I only dropped around 500g or so, and most of that was probably in wheels/tyres (went with Shimano R500s). To me the weight loss is not at all noticeable, but it weighs 11kg anyway, a fair bit when my carbon roadie is <8kg.
For me the enjoyment comes from low gearing, STI levers and good brake pads more than any kind of modern componentry weight loss.

Just ride & enjoy. If you're the sort of person who enjoys building and assembling - that's an extra ingredient in the experience.
Hit me up via the BNA dm; I'll get an alert. If y'know, you know.

You should realise that's a bit of a self fufilling fallacy. The new frame wouldn't be backward-compatible with old kit!

Glad to hear the improvements were worthwhile for you.2wheels_mond wrote:For me, a joy. I went with 10sp Tiagra on my Repco Superlite (originally 7 spd Shimano 300EX) - originally I was just going to get compact cranks but the opportunity to get the whole group cheaply came up and I'm not huge on downtube shifters (shock horror).

I'm actually the opposite and dislike STI levers.. weird I know.
I unfortunately won't benefit from the low gearing as there are no hills anywhere near where I live.
Better brakes will be great so happy there.

I like vintage bikes as they are but have always wanted to build something like this
Just after peoples experiences and findings after attempting something similar.

In a way yes and no. Improved in performance or 'quality' can be argued.RonK wrote:Well, let me put it back to you - if you took a modern bike and fitted vintage components, would the modern bike be improved? I know what I think.

Hyperglide shifting is a notable improvement.RIDER321 wrote: Have the modern hubs, gearing ect made a worthwhile improvement?
You may find dual pivot brakes an improvement over single pivot ones. But new pads make a bigger difference
Modern wheels are generally weaker than 6 speed wheels. 10 speed chains are much weaker. The extra gears are a "meh" unless you remove the front derailleur as a side effect

Dont think many/any have done this. Ive got an early 2000s Hillbrick which has got 8s Mirage from the 90s on it. Also building a early/mid 2000s Superbike with some early 90s DA. Went backwards there because I had those bits around, and they were good enough for me.RonK wrote:Well, let me put it back to you - if you took a modern bike and fitted vintage components, would the modern bike be improved?

Ive got one bike thats fitted with 6700 stuff. Only reason is, that I happened to find that groupset for very cheap. Running 10s DTs on it though, so in terms of riding, theres really not all that much difference to me, other than it being a compact and is my climbing bike. All my groupsets are late 80s/90s stuff, so there havent been massive improvements since, other than maybe electronic shifting, which I may try out one day.

The key for an upgrade like this is to have a great frame to start with.
Weight is not a high priority.
Your ultimate goal is to have the great riding quality of vintage steel with the luxury of modern shifting and braking.
I did the same thing with my old GEFSCO. A top quality, great riding and handling, Tange Champion no.1 frameset with a modern Campagnolo 10 speed groupset.

singlespeedscott - have to admit that when you posted your bike in the other thread I started influenced this build somewhat lol
The bike is also Tange 1 (not the blue one from other thread) and is nearly finished with the Ultegra 20 speed conversion.

All components are new but have an old-school look, including the Campag Athena 11 speed group. It is about 1.5kg heavier than my carbon/ultgra di2 bike but then I weigh close to 100kg so the difference overall is negligible.

Does that make my 1991(?) Cannondale vintage? Is the 10sp Daytona groupset on it still modern? (Quick google shows I don't know how old the frame is.)jaseyjase wrote:Do it
