SRAM Omnium crankset

has anyone used the 'on one' copies of the omniums? at £100 for the 165's with a bb and 48 ring it seems like a good deal but not sure how the quality will compare to sram

Yep - got a set when they were £80. Fitting is fine and no issues with the chainring, and nice and shiny too. I was either unlucky or the bearings are shite, RHS BB Cup, fell apart inside 3 months, and was in a right state when I looked at it. Since replaced with some Token BB cups.
