Strengths:    Looks

Weaknesses:    Doesn't last, bad seals

Bottom Line:   
The first time I rode with it I thought it was great. I got the bike for cyclocross and I did not ride it very often because I ride road too, and it was still road season. I had my first cyclocross race and the thing seized up, and got all gunky. I did some research on how to rebuild the bearings and I found out that the seals and covers always break when you take them off and FSA expects you to buy replacements for 3 to 10 dollars a pop. After doing more research I found out that the problem is that these are just crappy bottom brackets. I bought a dura ace 7900 BB and it is in the mail being shipped right now. It is my understanding that most people end up doing exactly this. I have even heard many people say that their LBS recommends just throwing out the megaexo for a Duraace right off the bat.

Strengths:    Rigid, lightwieght

Weaknesses:    low reliability, low durability, poor design (crank unscrewed once)

Bottom Line:   
Bearings completely froze after 1000km (and riding through some ocean water, I have to confess). Got a new pair, and 2000km later they are creaking...

Strengths:    Bike is great

Weaknesses:    BB started grinding an creaking with in 2-3 weeks under no load other than commuting.

Bottom Line:   
Paid $1150 for my new sleek Kona Unit only to have the BB grind creak and clunk with in 2-3 weeks - the bike is solid although the break scrape like a banshee.

I only commute for 15-30 minutes morning and afternoon and never put the bike under load.

Unfortunately the bloke I bought this from is a grumpy old bugger who likes to imply that you brke the bike rather than the bike being faulty, so I'm not in the mood to challenge him on - it even though it's still under warranty.

Will now buy a superior quality BB and swap it out.

Strengths:    Love the bike so far. If not for the BB and that the front is a 46-36. I plan to change 46 to a 50. This, I hope, should give me more high end. Aluminum frame and fiber front fork are very smooth on the road.


Weaknesses:    BB is crap and gettig use to using the Sram double tapp.

Bottom Line:   
Bike came with FSA EXO BB and only after 2 30 mile rides started to make noise. I've had other bikes with unsealed and sealed BB bearings that never craped out soo soon.

Strengths:    Unbreakable, in my experience.

Weaknesses:    None.

Bottom Line:   
My touring/commuting road bike came with standard FSA Gossamer cranks and Mega Exo bb back in 2005. I've ridden the bejeezus out of that bike, with heavy loads, lots of crappy weather conditions, and putting a lot of leg into the cranks almost every day, (I've weighed between 200 and 250 pounds over that time!)

The bb is still absolutely money. No creaks, clicks or squeaks; it's quiet and smooth. (I've had preventative maintenance done twice anyhow.) Maybe I was just lucky, considering the problems that other reviewers have reported, but my experience has been as good as it can be.

FSA SL-K crank removal - Mega Exo BB

Noticed a little play in my Mega Exo BB so I thought I would pull the cranks off (FSA SL-K) to make sure the BB shells are still tight. Removed the L crank arm bolts and I though the arm was supposed to slide off?? Left arm is solidly stuck on the BB spindle. Checked out Parks website and do not ... Read More »

Hello, I'm attempting to install a mega exo BB for my new team issue carbon cranks, and could use some guidance.
