What is it with DMR V8's? every one raves on about them and how good they are.
But I have managed to knacker 2 sets, both left hand pedel bearings clicking only after 50 miles on the first pair and 150 on the second.

Any one else had the same probs??

No mate have found them excellent
Do you lead with your left foot?

I thought that V12's were supposed to be preferred over V8's, as the V12 has sealed bearings (whereas the 8's are loose)?

I've run V12's since forever, and haven't had to do a thing with them. Ditto Wellgo MG1's (basically, a V12). And have had my DMR Vaults for about 6mths. All without issue.

Mind you, my knees click after 50miles!!

Yes I do lead with my left.
First pair I only rode to work and back a few times.
Second pair have just been on gental rides as I have been broken since april, Will pull them aprt at some point and see what s going on

My first pair or V8s got wrecked in a road crash on ice. but my second pair are going strong you just have to pack them with grease when you first get them, then top it up after a few rides, then just leave them to get on with it.
