• I'm also building my brother a bike as he's doing it too and with even less experience. He's training on the old 1987 Rockhopper but it will just be destroyed by the 'Puffer.

    We're building him the following:

    1. On-one 45650b
    2. Rockshox 30 Gold TK Forks (120mm travel, tapered)
    3. Deore M615 brakes (180mm up front, 160mm rear)
    4. SLX M670 shifters with RD-M592 and XT-M786 mechs
    5. FSA comet crank (38/24) - not sure what cassette to pair with this? and if it will need a 'chain device' I've never had a bike with a chain device.... what even is a chain device?
    6. On-one heavily discounted stem, bars, seatpost and clamp
    7. 650b wheels that I have in the garage (9mm QR but they're free)
    8. Brooks All Terrain saddle
    9. Continental x-king tyres

    So need to get grips, cassette and SPD pedals. Any recommendations?

  • Make sure to bring a few sets of spare brake pads and split-pins, as well as small pair of pliers to change them.

    And check your pads every lap - on a 12hr race last year my friend's pads wore all the way through the friction material, then through the backing pad, then started wearing into the pistons... you don't want to do that.

    Incidentally I am wondering if it's possible to make a device, similar to a flint-catcher I suppose, that slices off excess mud before it leads to complete clogging of the chainring.

  • Yeah, I'm working on my spares setup, as we're doing it as a quad it will only be around 6 hours each!
