Hi all, I want to upgrade my bike with a few parts from this UK company
, ceramic bearings, brakes, etc. Does anyone have any experience with these, is their any difference?

Thanks
 

I use the pully wheels on my dura derailure and have no problems, they work great!   I have some friends that are using the brakes and like them as well .

 great thanks, did you notice any improvement in mechanical friction

I have two sets of their road brakes and they are way better than Zero Gravity. They come 160 gms with pads and bolts and stop just as good if not better than Zero Gravity and stay centered with no fuss. I have an extra set if you want to buy them just PM me.

the roll very freely with my hand.... the amount of benefit is un-noticable but im sure its there.   The look cool though!

No logos, which I like. I wonder if they last and who makes them. They are lighter than the kcnc too.
