If I switch my 53/39 for a 50/34...

[Marty]

do I need to change my front derailleur too? I'm thinking no, but I'm
not sure. Pretty sure I'd need to remove a few chain links and move
the FD down a bit. Maybe a new BB too if I can't find a square taper
compact crankset.

Anything else to consider here?

Thanks.

I've switched to compacts on my bikes and the original Dura Ace/Ultegra
front works just fine. You just have to lower it a bit. Don't really have
an answer for the chain length question -- I was running 50/39's on the
original cranks. It's probably a good idea to check the length anyway.

Assuming the same cassette as now, I'd leave the chain length the
same. Going from a 53T to a 50T big ring, you could probably remove
one link. Not worth the effort.

Lower FD and remove 1 link, assuming the chain was proper length to
start with. We have a Veloce 172.5 compact, square taper deeply
discounted.

A standard FD worked fine for me when I installed a 50/34 compact,
just had to drop it a bit. This was a Shimano setup.

Art,
you have to remove two links, you'll know when you shift to the 34t.

Outside section+inside section= 1 link.

How much? BTW - this is DA 8 speed. I added a new 8 speed DA cog
set, new chain (SRAM PC-68 I think) and new FSA chainrings. Maybe
have 2000 miles on this stuff. So, my question is - if the campy
crankset comes with campy chainrings, will they work okay with the DA
8 speed FD and the SRAM chain that I have?

Yes it will but you will need a new BB..Compatible(Campagnolo AC-H)
start at $30..Centaur is $65.

$70 gets you the crank, BTW-plus $8 s/h. $100 for the BB/crank and
I'll pay shipping.

This is because Shimano is JIS and Campy is ISO?

I'd like to keep the BB that I have. Though, I have been looking for an
excuse to stop in your shop. I live in Longmont, which is why I'm
interested in the 50/34. I'm from WI and lived in MN for 13 years and I
never had a problem with 39/23 on any hill that I'd ridden while living in
either of those states. Not true since moving to CO. Left onto Lee Hill
from Left Hand Canyon (going towards Ward) was really tough (for me) in
39/23. :-) Old Stage is an almost complete out of the saddle grind fest as
well. I either need easier gearing or more time on the bike to make these
hills more manageable. Jamestown isn't bad with the gearing I have now.
But I think Ward would hurt a lot. Then there are all the bigger climbs
that I want to do that I think may be even more difficult. I have much to
explore around here and I don't want blow out my knees in the process. I
see lots of triple setups and compacts at work and now I understand why.

Thanks for all the help everyone.

That is correct..altho the same 2 degrees, shimano in millimeters is
alrger so the crank won't press onto the BB spindle the proper
distance. I know many will say 'poo-poo' but it's like morphing a Ford
water pump onto a chevy..lots of Campag BBs out there.
