Campy Record triple, 30 speeds!(6 posts)

|What do I need to change to convert my present Record 10 group to a new 2002 Record triple chainring. Thirty speeds! I do not wish to spend more than I have to and would like to use as many of the existing components as possible. Obviously, the crankset and the B.B. as major components but is it really necessary to change the deraileurs and shifters? Present set-up with standard 13-26 cassette and regular(short cage) rear der. Has anybody done a total bare bones cheapo change over by aquiring only the needed parts, example,the drive side crank arm, 30 tooth inner ring, chain ring bolts, Ergo power inner parts, front deraileur etc only. I would like to have the triple ring set-up for an as needed per ride type basis. (Mount Washington Hill Climb and other extended grinds) Hopefully, just swap the B.B. and crankset and ready to go.|

|You will definitely need a new rear derailleur as well - the existing one will not be able to take up enough slack to hold the chain on your granny gear. I believe you will NOT have to upgrade the Ergo levers, as I'm pretty sure all Ergo levers are triple-compatible.|

|Recognize that you won't be able to use the bottom 3-4 cogs from the small ring, the top 2-3 from the big ring, or probably the bottom 1-2 and maybe the top one from the middle ring, due to either chain rub on the rings or extreme chain angles. Add in the duplicates, and what your get is maybe 3 or 4 more gears. The primary (only?) reason you should consider this swap (rear derailleur, cranks, BB) is for lower gears - your new low would be 30 inches rather than your current 39. At 60 rpm climbing cadence, that's a difference of 5.4 vs 7 mph. If this is what you need, then go for it - you're looking at a few hundred bucks.|

|Cost effective solution for RD is a Chorus long cage. About $90 off the net. You'll have to dig around to find a triple crank and BB as they are very 'new'.
I also agree with the previous poster that the existing ergo front shifter should be OK.
Sounds like $400 to me. ????
I'd seriously consider a 13-29 cassette and der conversion first as that will cost less than half and the gearing would be fairly close. If you already have a medium cage der you only need the cassette.

Did this on my spouse's Bianchi in July. Worked fine and solved the problem...hills flattened very quickly. Triple isn't necessary, IMHO...

|Talk to www.branfordbike.com You can buy a medium length cage for the rear der. I think that will work. I don't know about the front talk to those guys they are very helpful and knowledgeable.
I had a tripple 8sp, I could hit every gear from any chain ring. Now was the chain line conducive to long chain and cog life heck no but in these radical gear combos your not spending alot of time in them any way. I'll also tell you that I have left the tripple as I felt I didn't need it and have not needed it and I run an 11-21. Of course riding style purpose as well as topography play a big part in this decision also. For me 20 sp are enough and the 39x21 suites my riding style just fine.
