What an interesting read the "http://www.campyonly.com/howto/ergo_rebuild.html" was, in particular the conversion info. This raises some questions for me which I hope you can help me with.
I bought a carbon bike recently for my wife, it has Campag Carbon Record Levers - 9 speed. The specs are below.
- Inexa C1 Carbon Frame (size 52 cm top tube C-C) New 2007
- Campagnolo Record Carbon Shifters
- Campagnolo Record Carbon and Titanium Rear deraileur
- Campagnolo Record Front deraileur
- SNG Ultralite carbon wrap Dual pivot brakes
- Sugino Qualete double crankset
- 10 Speed 11-25 cassette
I was very excited at the component list.
What I notice are the following.
1) The shifting action for the gear shifts is very heavy/stiff, not at all sweet and far heavier than my Shimano SORA shifters. Other have commented on this and recommended a shift cable change at least. I read in your article this was a reason for the rebuilding your Ergo levers. (worry)
2) The left lever requires a very long travel to make a shift in either direction. I need to take my hands off the bar to make the up shift as the lever travels some 6 cm in an arch, is this normal? I understand it is managing all the trim stages.
3) There is a Shimano hub on the rear wheel with a Shimano 10 speed cassette on it. I could not tune the shifting of the rear gears and it kept trying to climb between gears after a shift was made. I took it to my brother who is an experienced rider of some 25 years, we noted the 10 gear cassette and the 9 speed shifters and thought it odd. We changed the cassette to a 9 speed Ultegra set and could tune the rear gears nicely.
- The shift levers only have 8 clicks so we figure the levers would never select 10 cogs
- The rear hub and cassette is Shimano as it the 105 chain. I thought Shimano and Campy were not interchangeable.
4) I wrote back to the seller and he said he had upgraded the 9 speed levers at a bike shop and that the 10 speed cassette was appropriate. That he had serviced it before packing in the bike box for shipment. Maybe the derailleur had been knocked in transit. He referred to your page on the upgrade of older 9 speeds to 10 speeds.
"The drivetrain is actually a 9 speed that was converted by a bike mechanic to full 10 speed. Campagnolo retain the ability to upgrade quite easily. With regard to the 9 speed ergo levers, a small cam change was the only thing required to make them identical to a 10 speed ergo lever. Likewise, there is minimal difference between the campagnolo 9 and 10 speed rear derailleur. (The jockey cage plate closest to the spokes is thinner on the 10 speed rear derailleur. Due to the 10th cog on Campagnolo 10 speed being bent
towards the spokes so the rear derailleur has to get closer to the spokes to shift to the biggest cog. Limit screws will make either rear derailleur stay out of the spokes and shift to the biggest cog )
This procedure is widely documented and is desciped in Zinns "The art of road bike maintenance" and can also be read on websites like campyonly.com <http://campyonly.com> http://www.campyonly.com/howto/cam_change.html <http://www.campyonly.com/howto/cam_change.html>
Therefore, the 10 speed casette it came with should be working like a treat. In fact, I serviced it before I dismantled and packed up and it was running smoothly then so I am unsure why it should be causing you issues now. Perhaps it recieved a slight knock and the limit screws need re-adjusting? "
What I don't understand is that a Shimano cassette and hub are on the rear and that the lever only has 8 clicks (9 gears).
Your thoughts on this please as I think the seller is genuine but the items above don't gell for me.
1) Should the levers be very stiff and what does this indicate?
2) Shimano cassette and hub?
3) 10 speed conversion but only 8 clicks.
Appreciate your time
