|This year, I built up my TT bike with a single outer chain ring (52T). The back cluster is 12-23. This way, I could avoid using a front derailleur/lever, since I only use 3 gears during TT's anyway.
The side effect is that I drop the chain quite frequently (despite shortening up the chain), and w/o the front derailleur, I have to get off the bike to replace the chain.
I've seen some Euro pros use single chainrings but have side guard rails hooked up. Anyone know where I can get them? Are they just the same rails that you see on kids' Huffys?
