Hi There
Apologies for the long delay in getting back to you all. It has been a few weeks.
I just wanted to say a big thank you as with your help I managed to change my triple to a double and change the cassette.
Actually I could not get the cranks off and did not want to damage the frame, so simply...
- removed the inner granny ring
- left the existing 115 bottom bracket in place,
- changed the chain and the cassette to 12-32.
- change my second chain ring from 42 to 39 using an aftermarket ring I found online.
- new bar tape
- new specialised seat to replace my very worn Bontrager one that came withe bike.
Generally works well. There was no need to replace the existing "Long" rear derailleur. I find I now have much greater range.
The official Campagnolo chain replacement guide suggested my derailleur should be more horizontal when replacing the chain, however I found using the generic method worked just fine.
Attached is a photo of my bike post upgrades. Thankyou all.
My wheels...
