OE cost is 40% more than the SRAM Red cassette
That still makes a replacement cassette the best part of £200 by my calculation, and I regard them as a consumable item – in muddy conditions (and we’ve had some of them recently) I seem to get through them quicker than tyres.
That helps my decision making – I was hovering over the buy button for a CCDB frame, then started thinking that the 29er with XX1 looked worth waiting for. A bit of Googling now tells me that the CCDB expects a service every 100 hours and you can’t do it yourself so the 26 inch frame with the Monarch is looking very attractive. Just need Mrs R’s approval on the colour!
