Look for a 46-30 crankset option. It will allow you to keep the current cassette and rear derailler and still buy you a useful drop in gearing. I am using that on a 135/74 mm BCD triple with just...

If your current Veloce drivetrain is healthy, consider keeping everything BUT the crankset, and swapping it for a compact (50-34) or subcompact (46-30) set. I swapped a 46-30 into my Veloce 10-speed...

Probably any 2 x 10 drivetrain on any road bike with relatively short chainstays will do this in one or two small/small gears if it has a 16 tooth chainring difference and a standard chainline. You...

I realize I am in this thread late, but it struck a cord with me as I struggled with knocking myself. It's not chain slack, it is the outer body knocking back and forth on sloppy bearings as chain...

Yes, See the picture I grabbed from sheldonbrown.com. It shows the inside faces of a few different styles of ramped and pinned rings. From the outside face you only see the pins. They look like...

If it is BCD 135 and 74, you want Specialities TA Vento rings for middle and outer, and Zelito for the granny. Be sure to specify middle, or you will not get the shifting aids to get up from the...

Swissstop sells pads of various compounds to address exactly that. I believe their name for low profile pads is EVO. Also, check that there are no plain washers inside the arms in your current...

Thanks steelbikeguy for posting the chart. It saved me the trouble.

The OP is very close to his solution I think so these comments may be a touch too late, but here they are:

CliffordK has identified the issue correctly, I believe.

I just "doublized" a 50-40-30 triple to 46-30. It went well, but it did depend on finding a 10-speed compatible, ramped and pinned 46T...

I would not trust myself to never shift into big-big if physically possible, ie not blocked out mechanically. It would be interesting to see if anybody knows a way to do that without taking out your...

If you can find a crankset that will accommodate both your "big" and "small" chainring pairs, there will be less work in the changeover than when changing the crankset. How about a 110/74mm triple,...

The 135/74, 130/74, or 110/74 triple crank without the outer ring is the way to go. A "doublized triple", so to speak. With the specified BB axle length, it should put your 46 in line with the...

Converting hubs is a PITA and then you need to carry about a 15 mm wrench. The nutted skewers you ordered were the answer, especially of they took a lightweight standard tool like a security hex...

Front brake for rear, yes. That's the smart approach and why only the one long (70mm) bolt is required to convert both brakes.
