The top video is standard bottom bracket, the bottom video is Enduro Ceramic bottom Bracket.
This is no clinical trial by any means, but it does highlight the minimal friction ceramic bearing offer riders. I did some very quick sums, at a cadence of 80 RPM x 60 mins = 4800 RPM per hour x 12hrs (assuming you are pedaling half the time during a 24 hour event)= 57,600 pedal strokes on each leg. Over this duration any reduction in resistance will help a lot.
I have chosen not to change the bearings in my Mavic Crossmax SLR's purely because we all know Mavic wheels roll better than anything else on the market.

Now I know how good the race track is, I am now very keen to race on it. As for the perfect bike, my cyclocross of cause.

The second upgrade involves my race bikes. I have got hold of some Enduro bearings from DIYMTB and they are going to help me make my bike more efficient to ride. Firstly the standard BB was replaced with a Ceramic BB, now you can turn the pedals with a feather. I would also expect the ceramic BB to last longer when the rain come because there should be significantly less corrosion due to the non metallic surface. I also replaced the lower jockey wheels withe ceramic ones to reduce friction a little further.

As for how the Unit 29er rode - bloody brilliantly. They are an absolute hoot to ride, you have to work on it (by that I mean everything to do with mountain biking) to get the most from the bike. But this is great for training. I think it will be heading out on may more rides in the future than first thought. It might even see a few upgrades ....

For me this ride was about getting some base miles back into my legs after the body has had a good rest off the bike. There is no better way for doing this than with a great bunch of mates in the Dandenongs. The highlight of the ride (and my max heart rate,) was the decent down the One in Twenty (Sasafras to the Basin on Mountain Hwy). A bunch descent keeps you on your toes that's for sure. Working turns whilst keeping the pace very high. Heeeeaps of fun.
