Gearing question

[norcalbiker]

I am using a Record compact (34/50) with 12/25 rear. Would I have any problem to swap my rear to 13/26 from time to time?

TIA

Go to Campy's website and look up the capacity of your rear derailleur.

My rear derailleur will accomodate the cassette.

Just swap the cassette and go. The wrap on both is 13T and the short cage will handle the 26T cog.

Cool. I always believe DIY component tinkerers should always go first to the manufacturer's websites for technical info. Not only can it save you a lot of grief in the long run but you learn a lot about how the choice of one drivetrain component affects another.

You may want to confirm that the chain is long enough should you cross it to the 50/26. If you can do 50/25, odds are very good it will work -- worth checking IMO before riding.

Shouldn't be any technical issues (except chain length, as noted above), but you will get more duplicate gears. There's a great tool on Sheldon Brown's website that allows you to input your chainrings, select a cassette and get back a table based on gear inches, gain ratios or meter development. Pretty cool... and it let's you see what you'll have before you make the swap.

This is exactly what I'm waiting to hear.

Thanks
