[HeyYou]

I learnt something too.

 

So, the cogs from an 11 speed cassette will slide onto a 9-speed freehub? All you need are the spacers from an old 9-speed cassette to put in between?

 

What chain should one use?

A 9 spd chain will work, the cogs are very slightly thinner, but not enough to make much difference. 10 speed too will work.

Use the lower series cassettes and not Chorus, Record, SR as these have different alloys and certain sprockets are held together in a cluster. The Veloce and Daytona have loose sprockets which are stronger and a slight bit cheaper.

Gipiemme by Simplex

 

 

Thought I had a pair if these Gipiemme DT shifter but only found one. Will check over the weekend. Very similar to these Ofmega levers.

 

 

Modolo levers similar to Gipiemme branded ones.

That's an appropriate nom de plume Loose Cog

Hi guys

 

Need a bit of help regarding cassettes. Will the new Campy cassettes be compatible with an early 90's groupset? I have a 9 speed Campy cassette at the moment, 11-21, but need some extra gearing for the hills. There is guy selling an 11 speed cassette, 11-25, on the Hub and am wondering if I can just drop to cogs and put it on my bike? The ad is below

Hi Warren

 

Last year I had the same experience as you are going through and I found that for casual training rides I wanted lighter gearing on my 2000 9 speed Bianchi (for cruising out at the Cradle). I bought a 27-12 Campagnolo Centaur 10 speed cluster and used the 27, 26 and 25 tooth sprockets which I combined with sprockets from my 9 speed cluster (which was virtually new). The 27, 26 and 25 Centaur sprockets were riveted together so I removed the rivets and replaced them with 3 mm screws and self locking nuts which I got from Builders Warehouse. (The nuts are fitted on the inside of the cluster i.e. where the spokes are.) I'll get a photo and post it shortly. Having separated the 27,26 and 25 tooth sprockets, I re-shimmed the spacers using tiny washers and then re-assembled them using the 3 mm screws and nuts with thread locker for extra safety. The 10 speed spacers are 2.4 mm thick while the 9 speed requires 2.7 mm spacers. The 10 speed sprockets are 0.1 mm thinner than the 9 speed sprockets and I took this into account as well in shimming the 10 speed sprockets. The whole set up works perfectly and all the hard work (about 3 hours) was really worth the enjoyment of using the lighter gears.

What a compliment! You made my day, thanks brother. (I'm a lawyer in my spare time!) Here is a photo of the modified gear cluster taken through the wheel. I cut off the 3 mm screws flush with the nuts using a Dremel cutting disc to prevent them from snagging anything. I then daubed the cut off screws with red paint to prevent rusting and also for quick inspection. They look cool when they are spinning.

It is always good to see people willing to do this kind of thing. Meaning, to make old things work and live on by using infinite care, skill and patience. You used a level of "preciseness" that I admire. (As opposed to quickly slapping together something that kind-of-works.) The time alone makes it uneconomical, but the pride when you get it right, is a reward enough. Too many people have been conned into throw-away consumerism.

I agree with you 100%. It is not always about, or measured by, economics - it is about art and creative expression. What you say reminds me of the concept shared by Robert Pirsig in his epic book, Zen and the Art of Motorcycle Maintenance. In the book (page 92) he is adjusting the tappets on his Honda and his mind drifts to the "idea" of "dimensional precision". He writes: "There is no perfectly shaped part of the motorcycle and never will be, but when you come as close as these instruments (referring to precision instruments) take you, remarkable things happen, and you go flying across the countryside under a power that would be called magic if it were not so completely rational in every way."

Worst bike I have seen this year.

 

It should be green to match my envy.
