After the around the block test ride where things seemed okay, I relocated the bike from my van (hot interior) to the cool basement. The next day I headed out for a long ride but the crank was klunking so I only got to the corner and returned. After a long battle, I got the crank out. The axle is aluminum. The bolts are aluminum. The self extracting rings are aluminum. Someone apparently severely over tightened the bolts trying to 'fix' the klunk. Weill they striped both bolts and damaged the axle threads. One bolt had the removal lip sheared off. I removed the removal rings and used far more force to remove the bolts that I wanted to. I figured at this point it was all shot anyhow. I used a steel shaft and the shot mallet to get the right crank off. Lots of close examination and I found the aluminum insert in the left hollow carbon crank is slightly loose. ie, trash. That was the source of the klunk. Kinda like an old school cotter pin that was loose. Repeated searches on the web reveals most of these cranks have failed. There was a 2007/2008 recall on them for improperly heat treated axles. Not the issue on this one. FSA made the cranks for Cannondale but they have different specs. The extractor threading is larger than FSA branded FSA cranks. I ordered a special Cannondale bb30 crank extractor but it doesn't fit. At this time, the left crank (trash) is stuck on the axle (trash). The frame has an aluminum sleeve in the bb (good) to house the bearings (good). The coop had a FSA Omega BB30 but the axle to right arm press fitting is loose and there is no fixing that one. I bought a very reasonably priced FSA Gossamer bb30 2 piece crank set and installed that. It's working fine. From what I can tell, Shimano doesn't make bb30 cranks. There are some aftermarket adapters to fit better cranks to bb30 frames.
A 44 mile test ride and a spoke broke on a very smooth bit of road surface. Rode the last 20 miles home in 'limp mode' so I wouldn't cause any more damage. Boutique wheels! Straight pull Sapim brand spokes, about 281 mm. $18 for 1 spoke on ebay or a 3 pack for $26. A local bike shop was open sunday and they had a couple of DT straight pull spokes in a close enough lengths. Black instead of silver but who will notice. Every other nipple is black, the others silver. Tire off and axle has to come out to replace the left side radial spokes on the Easton wheels (not oem).
I did find more surface damage on the frame. Chain suck took off about 1/2 square inch of the finish. And the front wheel qr was over tightened and took the finish off the dropout. Seriously, carbon bike owners need to buy torque wrenches and get trained on how to use them. Snap.
My initial opinion of the ride quality has been over ridden. A long ride and I say it's pretty good. The less weight compared to my Litespeed with it's heavy wheels and accessories is noticeable. it certainly rides much nicer than the many ~$1000 aluminum bikes that i've test ridden. But I would not take on Iowa gravel roads. Seems too delicate for that kind of abuse that I often inflict on the Litespeed with no issues.
