I picked up a low end Cannondale Hybrid (1999 H300) to get back into cycling and to learn a few things about bike mechanics. The bike is great for fitness, but I've started to tear it apart and refit with some inexpensive upgrades, as that is the stuff I love to do. My latest project has been to replace the BB (110-68 square taper-JIS) and upgrade he crank. The original spec listed the crankset as a C.P.I, but once I pulled it I found it to be a 175mm Shimano FC-M290 and it had been the subject of a recall in the late 1990s, so I'm glad I'm doing this upgrade.

The original crank was a 24/34/42 which I plan to replace with a 30/42/52 FSA Vero crankset. Here is where my problem lies. The new FSA crankset slides in too close to the frame. Upon closer inspection I have come to realize the not all crankset BB shafts are created equal. The original Shimano crankset BB shaft extends beyond the innermost chain ring by about 1/8" inch...an "outie", so to speak. The FSA chainring BB shaft is recessed, an "innie", and therefore slides too close to the frame. So I have learned that cranks come as "innies" and "outies".

Can anyone recommend a reasonable triple crank that will fit my "outie" needs. I'd like the largest ring to be in the neighborhood 48-52 teeth. When I look at pictures of cranks, it is really not possible to determine the BB shaft length on the inside. I'm sure there is a more technical description, I'm just not sure what it is.

Thanks to all who have taken the time to read my lengthy post. Any advice will be greatly appreciated.
