Ergopower - Change from 8Sp to 10Sps?

[hmsgenoa]

Are there any Campy equipment gurus who could tell me if i could rebuild 8 Spd ergo levers with 10 Speed internal part (EC-RE061) to replace 8 sP part (EC-RE015) on the right hand levers?

Would there be complications mixing an older 8Sp derailleur with 10Sp chain & caSsettes?

Planning to build a road bike to take to the alpine tour stages, rather than the mountain bike I've been uSing. Could do with a many extra gears a possible in current state (but would prefer not to spend a fortune). It will depend on avaiability of the parts. If anyone has done this though their advice would be much appreciated.

You need new levers and a new hub and rear mech The 9 speed rear mech will work OK on 10 speed the new 10 speed levers can be updated to 11 speed.

Should be able to get hold of some 10 speed equip fairly cheap 2nd hand personaly I dont like the 11 speed .

Thank you very much Brian. Blimey I think I'll have to get on ebay and get an old record 8 sp 13-26

I made do in Colombia in 94 with 7 speeds up 'La Pintada', only mountain where I've felt the effects of altitude. Oh and what a descent; I had a classic 'film' type moment where I came round a hairpin and was faced with two lorries side by side The way they drive in Colombia is unbelievable.

Since then only ridden up mountains on a mountain bike.

But at least I know now 10sp might be a practical limit. I'll probably just end up in bottom gear at the moment anyway so will make do with 8. Cheers

yes it is possible to build 8 speed up to 10. it is pretty easy and can be done in less than an hour from the time you remove the shifter from the handlebar until you are ready to put it back on. it can be done faster with some practice. here is a useful site. you can buy all of the parts you need there and a build manual, too, but i have seen the build manual online. do a bit of googling and you should find it.

you will need to change the cranks, chain and cassette to 10 speed, of course. i have used an 8 speed derailleur, but a nine or ten works better. if you are clever enough to get this far, you can modify an 8 speed derailleur by removing the adjustment screws and doing a little filing. the front mech will work fine as it is.

hope this is useful. by the way, my everyday bike is a mix of 9 speed mirage ergo shifters built up with 10 speed record internals (on the rear shifter only), 9 speed veloce derailleurs, (maybe, i don't remember) a chorus 10 (12-15) cassette, record crank and athena brakes. it works flawlessly, in spite of needing a good cleaning.

I will add
you can keep the cranks and just change the rings. If you use the 8 speed derrallieur change the jockey wheels to 10 speed and change the jockey wheel bolts too. If You want a lower gear than 27 and decide on a new rear derrallieur go long cage in 10 speed and get the 13-29.
The 11 speed rear goes to 29 without a long cage.
I like the 11 speed better.

Thank you very much Gregod, very useful information and a great site you've directed me too, really appreciate it I think I'll make do with 8 for moment, doubt I'll get it done before July, but know now that I will be able to change the setup which is exactly what I wanted. Cheers Ian

Thanks a lot Master 50, I found the frame I'm building up needs Italian cups so need to get a new bracket. I've seen a centaur 2008 10sp chainset with bracket for £100 sterling so think that's probably a cheap way of getting 10sp rings too. Info on the derailleur capacity very usel too so thanks again, cheers Ian.

Thanks everyone for your help, can't wait for the horror to appear on my face when faced with the ramps on the Col D'Agnel!

Unfortunately, it cannot be done. The innards, the thru bolt, the width of the lever, the flats of the shift disc makes it not possible. You can convert to 9s, but also need a 9s Campagnolo rear wheel(cannot put a 9s cogset onto a Campagnolo 8s freehub).

To be more precise, the shift disc, EC-RE-061, the flats that engage the thru bolt are a different dimension than the 8s thru bolt and the 10s thru bolt that s required, is a lot longer and also doesn't match with the shifter front dimensions.

You can use 8s cranks on 10s w/o changing any chainrings and if the 8s RD is not worn out, you can use that too and don't need to change the pulleys. Why new 10s pulleys with a thinner chain?

Methinks the gent that sadi it was possible was thinking of 1999+ levers, which CAN be converted to 10s or 8s.

Busted Knuckle has got it right--the Campy cassette splines are different ,unlike Shimano, but a Shimano wheel can work,with a bit of juggling.
Easiest way to get lower gears would be to consider a triple chainring,
You will need a front deraillier[look for a cheap mountainbike one]
Later 8-speed lefthand levers will handle triple,or use a downtube lever for the trip.--Depends how much money you wish to spend. Your existing rear derailleur
will work if you dont go big/ring big sprocket and set it up carefully.
It can be done on the cheap ,or just go and buy a groupe set[Joke]
Good luck

damn. you're right. i forgot that i changed the rear wheel, too. i did use an 8 speed derailleur for a short time on the 10 speed set up, but shifts were inconsistent, so i changed to a 9 speed which works great.
