    I’ve had my pinnacle dolomite almost exactly a year now and it looks like the FSA bottom bracket is starting to go again. This will be the second time I have replaced it. I reckon I average about 90 miles per week. I rode my old Trek hybrid for about a year and a half covering the same route and didn’t have any issues. Is this normal wear for this type of bottom bracket or is there a better lasting one I could install?

    You just need a decent square
    You just need a decent square taper BB. Should get 30,000 miles at least. So long as you grease and adjust it about every 5000 miles.

    Load of expensive modern “tat” that cures a problem that didn’t exist, these external BB’S.

    I’ve got an FSA MegaEVO 386,
    I’ve got an FSA MegaEVO 386, doesn’t fit Ultegra (its too big 🙁 ), so I’m stuck with this crap untiil I can afford a shimano chainset. Basically I’ve learnt to make sure it always gets a good lube after every wash and at the weekend after just over 1000 miles I removed the crank, pulled off the Bearing seals and gave it a good clean (as much as I could get to anyway), topped up the grease and put it all back together again, the amount of water that came out once the grease went in was worrying. This is the 2nd time I’ve had to do this! I agree its junk.

    I have a deore HollowTech2 on my CX and that hasn’t needed touching in almost 3000 miles and feels like it will do the same again before I even have to contemplate just giving it a clean out, let alone replacing.

    I had the same thing, and
    I had the same thing, and after lots of research I thought I would just go for it, I replaced my fsa mega exo bb with a shimano ultegra bb, and true it is a snug fit for my fsa gossamer crankset but it works just fine, no more creaking, nice and quiet and smooth running, people on here saying about their mega exo bb’s not lasting long, but mine had done about 6000 miles in all weather conditions

    Funny thread to stumble
    Funny thread to stumble across, as I’ve literally just pulled the FSA bottom bracket from my bike to throw the PoS away. It started to fail (lots of creaking) after less than 2000km. A bit of web research quickly showed that I’m far from unique.

    Now I have the measurements, I’ve ordered a Shimano replacement. They seem to be much better quality and life expectancy, and it’s a cheap component. The only reason I could imagine a bike shop wouldn’t use them, is to keep you coming back..

    Depends on what model of FSA
    Depends on what model of FSA crank you have fitted – Gossamer and Energy are compatible with Hollowtech 2 but a lot of FSA models aren’t e.g. Omega as they use a 19mm spindle, unique to FSA.

    True but these days things are fit and forget really.The Shimano bb that fits with fsa chainset will run with no service for years.FSA need to get there act together.That said Campag gear is pretty naff also, 😐

    Thanks for the advice. Took my bike to a local bike shop and they used an Ultegra bracket. Cheaper and much longer lasting.

    Agreed. FSA bottom brackets
    Agreed. FSA bottom brackets that Evans ship with new bikes are pony. I had exactly the same problem with a Pinnacle, switched to Shimano and haven’t looked back.

    Evans Cycles tech line will tell you that you must Must MUST use the FSA tat. This is a crock. They simply want to sell you £50 worth of fast-wearing cheese instead of £15 Shimano goodness.

    Clean up them threads, use Coppaslip, torque it right, take care putting the spindle through and you’ll be fine.

    The FSA mega exo bottom
    The FSA mega exo bottom brackets are truly dire.

    As said above, you can get an Ultegra one that will work with FSA chainsets for small amounts of pounds (if you shop around).

    I think the FSA bb on my commuter lasted less than 900 miles. The Ultegra replacement has lasted over 7000 miles so far.

    If you want something simple
    If you want something simple that lasts I would go for square taper over an external BB chain set. The wear tends to be down to externals needing to be tightened to a rather narrow torque setting, slightly too much and they eat them self in rapid order. 105’s are known for it as well.

    Recently swapped a friends FSA P.O.S for an Ultegra for about £15. Should be good for 5000k plus.
