Strengths:    Nice colour

Weaknesses:    less than 2 month from new and the b/b has failed.

Bottom Line:   
The bike came new fitted with this FSA b/b. Started griding after about a month but quietened down and thought no more about it. Noticed a small amount of play in the b/b last night which after 35 miles today has turned into near enough a total failure.

Similar shimano products have lasted three times as long.

Will be replacing it with a shimano setup and see-ing if I can get a replacement under the bikes warranty.

Strengths:    Strong, no flexing.

Weaknesses:    Seals gave up after 8 months, started creaking, allowed mud and dirt into the bearings.

Bottom Line:   
They are very strong and theres little or no flexing, but it just doesnt last. I took them apart and found that the non-drive side had seized up, gone rusty and was filled with lots of Welsh mud. Im going to upgrade to Enduro Ceramic bearings and replacement cups and see if they are better.

Submitted by Mark Doyle a Cross Country Rider from UK

Date Reviewed: September 8, 2006

Strengths:    Stiff, smooth and light.

Weaknesses:    The product doesn't last very long, had it about six months. Probably due to not re-installing with a torque wrench. Cartridge bearings are easily damaged with too much side loading (over tightening). The plastic bushes between the axle and bearing are very britle and break easily. Due to muddy condition in Britain and Les Gets in over summer bearing have worn out and need replacing.

Bottom Line:   
Will try another one, but set up with park tool torque wrench. If that doesn't last maybe back to the old cartridge bottom bracket.

I've noticed play in the splines of my FSA crankset. It turns out that you should Loctite the splines with #641. I can't get any. Can i use 640? Will i end up bonding them together forever? (640 has 3x the shear strength of 641)Read More »
