Phil’s road bike

Phil asked me to build him a light, comfortable bike with confident handling. He had a good fit that I could design around, and requested an integrated seatmast and matching custom stem. We choose to go with a US-made carbon fork from Allied, which mates to the frame via a custom English headset that fits the tapered steerer without using an oversize headtube.

There is a modified Thomson seatpost for attaching the saddle, which has an internal wedge for height adjustments. Wheels are Enve 3.4 rims laced to Carbon-Ti straight pull hubs, matched with a SRAM Red AXS groupset.

Paint is by Colorworks, and the final weight as shown is 17.3lbs.

  1. The ISP looks great, very clean! Is the installed quill seatpost an in-house modification or is it manufactured by Thomson? How does the force of the internal wedge clamp affect the structural integrity of the stainless steel seat tube? This looks proper compared to using a seat mast topper.

    • Thanks for the comment – the seatpost is modified here to have the internal wedge for the seatmast. It is a cromoly seattube on this bike, and the tubing is plenty strong enough to support the wedging action of the seatpost. I prefer this look too!
      Best, Rob.
