Arkose R1 (med) gravel build

Posted on
  • As below, new Bombtrack build in progress so the faithful servant needs to go. It's seen many different builds, but currently in a GRX / 105 1x spec.

    F&F: Pinnacle Arkose R1 medium
    Shifters: 105 R7020
    Cranks: 105 R5800 170mm w AbsBlack 42t oval ring
    RD: GRX812
    Cassette: SLX 11-42
    Wheels: Shimano RS370 (19mm int)
    Tires: Gravelking SK 43mm (not tubeless currently)
    Bars: Zipp XPLR SL70 44cm
    Stem: Prime 90mm
    Seatpost: Prime Orra gravel 27.2
    Saddle: Specialized Phenom 143mm

    Looking for £800 >> £790 >> £780 >> £770 >>£760, collected Esher or St Pauls.

  • That's a really nice arkose.


  • tape ID?

  • This is great, wish it was my size! Glws

  • Cannondale 'Knurlcork', not super tacky but will survive several re-tapings

  • Damn it!
    need one in small otherwise this checks all the boxes for me

  • Have a 60mm stem and narrower bars if that can shrink it enough for you ;)

  • Price drop, £790

  • Could potentially sell with Hollowgram 35 wheels off my CAAD12 too (so can include the QR adapter for the rear hub, as TA 12mm now fitted). Has GK 35mm slicks on there now for super-commuter setup. £500 extra alongside the current build, £1190 instead of the Shimano wheels, or could sell separately too.

  • Alternatively, can also spec as a 2x with 105 R7000 chainset, RX800 rear mech and an 11-34 cassette for a bit extra. Any interest?

  • This generation of Arkose is particularly good. Full routing for dynamo and lighting. Rear seat stays flex for comfort. Triple butted tubing. Carbon steerer on the top two models. Absolutely love mine.

  • PM incoming

  • replied, and copying the geo info here for reference too

  • Agree, I had an old 2017 SS Arkose too which felt and looked much more industrial. These new ones have way better clearance too, big ticks in a lot of boxes!

  • Love mine too, same gen, surprised this hasn't gone yet. Glws

  • Price drop £780

  • I'm interested but think it could be marginally too small for me (5'11) - what's your height for reference?

  • I'm 179cm, so 5'10 and a smidge and fits me fine. Can throw a 100mm stem on if preferred too, but think you'd be ok for sizing.

  • neat :) glws

  • Price drop, £770

  • Pretty sure this is slightly too small for me, but could I ask what’s the measurement from centre of BB to top of saddle in these pics?

  • Sorry for the delay, that's set at 750mm

  • Thanks for this. I've been trying to convince myself it'd fit me but I think it is just a touch too small. Rad bike, surprised it hasn't gone yet!

  • Price drop, £760
