At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
FSA's MegaEvo Road Bottom Bracket has been working hard through the last few winter months and is proving to be durable and resistant to the elements. The bearings came well packed with grease, and everything is running smoothly. There is some tough opposition on price, though.
The MegaEvo bottom bracket allows you to run a crankset with a 30mm axle diameter (Shimano, for instance, uses a 24mm) on a frame designed to work with a BSA threaded shell. I've been using it to test FSA's Powerbox chainset.
From what I've found, the MegaEvo is a bit of a fit and forget item. The bearing cups threaded into the frame smoothly and the whole setting up was achieved in a matter of minutes.
The quality of the finished components looks to be good, and the anodised aluminium sleeve is a nice touch over a black plastic one – it's just a shame that you won't see when it is inside the frame.
Behind the dust shields on each cup you'll find a steel bearing; these were well packed with grease, not something that is always seen straight out of the box.
Everything ran smoothly from the off, and while it has only been around three months of testing so far, the weather has been wet for a lot of it, and the roads frequently covered in that liquid salt sludge you find after many a frosty morning.
And everything is still running just as smoothly – and quietly too – with a peek behind the dust shields showing not much in the way of contamination. I will keep you posted if things change quicker than expected as the miles continue to increase.
Overall, the MegaEvo has been delivering a good performance over the winter months, with very few signs of trouble to come. It's pricier than some on the market, although not by a huge amount.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
