I ran a Veloce compact on my Tecnos for a while - has a braze on Front Mech. I used a medium cage front mech, and both a short and medium cage rear.
The whole thing was flawed for me. Worked fine but I found too many dupe gears. The biggest annoyance. I found with compact is that when you run out of gears on the small ring, you have to go a long way back on the block and up on the front to get the next logical gear. Was just a complete PITA. Also, even with 50x12, it ain't big enough going down hill, and 36x25 ain't always small enough going up as I get older.
Commuter / Training bike now has a Campag Competition triple, with med cage front and rear, 52x39x30, and a 12-25 block 9speed. Job done. The triple chainset was eBay for £27. Had to bid on a few before I got one at my preferred price...
