Irvin’s V3.1

Irvin’s V3.1

Allowing Eric at Colorworks to work his paint magic takes a bit of time, as does getting the studio shots done (thanks once again to Tina Buescher), but I can now show off the finished build of Irvin’s Tron-style bicycle! I posted the pre-paint photos a while back, but it sure looks better all assembled. The matte/gloss combination on the paint is hard to apply, but gives a stunning finish, complemented by the matte carbon THM cranks and Dura-ace 9070 groupset.

This is the first frame that I have done with carbon seatstays – adding to the carbon ISP and headtube from the previous Superlight V3, the carbon stays save around 40g over the regular slender steel ones. The carbon tubes are bonded in place, and have an additional mechanical fixing consisting of a small titanium pin through each joint.

As shown with Enve SES 3.4 carbon tubular wheels, the weight is right at 13lbs. The fork is a THM Scapula, painted to match, whilst the stem is a custom English steel (122g) with a mounting boss built in for the Di2 control box. The tubing is mostly True Temper (with one of my few remaining (now discontinued) S3 aero downtubes), with Enve supplying the carbon.




  1. Are the brakes Zero Gravity? What are the cables?

      thanks, Rob.

  2. Nice, nice! Very interesting and pure individualism. It is possible in the feature to buy a bike with this frame?
