Got the 20mm wheelset and want to give the bearings their first service but can't undo the locknut as it keeps spinning and there is no visible means of holding it - any idea's?

Cheers P I saw that and me thinks I need oversizr cone spanners as mu 16mm one's are nowhere near the size needed.
yes you need a 28 mm cone spanner [url= http://www.allterraincycles.co.uk/product/116505.html ]here[/url]
for the rear you need to put an allen key in the lock nut to get that off (took me ages to figure this out) and then the 18mm cone spanner i think.
where are you based

17mm (m775 rear)
Thanks gents me thinks I will bring it up to CRC to let them see if it is a warranty issue - notchy bearings at 5 months old ain't good
My cones came loose, its cup and cone bearings so i dont think you'll get it under warranty but worth a try. If you've done a lot of winter riding in poor conditions its probably just grit in the bearings. I prefer this style than sealed bearings , dont last as long but simpleand cheaper to fix
