Speedvagen: Sizing and Geometry

Every Speedvagen frameset includes the frame, an ENVE carbon fork, and Ritchey seat post head. Each Speedvagen, stock and custom, includes a seatmast sized specifically for you.

Stainless steel is a functional design element used on every Speedvagen as well. You will find it in high-wear areas including inside and outside of the dropouts, bottle bosses, Di2 contact points, on the seatmast collar and  the front derailleur collar on the carbon seat tube upgrades.

General Frame Specs:

  • Brake bosses on cross bikes are Paul specific
  • Front derailleur mounting: Braze-on for road with a steel seat tube. 31.8 clamp for road and cross with carbon seat tube. 28.6 clamp for cross with a steel seat tube.
  • Uses a standard 1 1/8" headset
  • 130 mm rear spacing for geared
  • 135 mm rear spacing for single speed
  • 68 mm English bottom bracket

Geometry :

STOCK: Stock frames come in increments of 2cm, from 48 to 62cm. Detailed measurements and angles can be found in the charts below.

SEMI-CUSTOM: When it comes to the semi-custom, we lengthen (or shorten) the head tube to help get the handlebar to the right height and raise (or lower) the top tube to keep things proportional with the headtube length. Both of these will help in giving you the right saddle to bar drop without too many, or too few spacers.

FULL CUSTOM: A full custom Speedvagen is where we can really dial in the proportions for the individual  and make a bike that will be perfectly balanced for you. Every measurement, cut and angle is made to fit your exact specifications. A custom Speedvagen includes a fit session here at the Workshop with Sacha.

The frame is designed from the ground up just for you and not based on any template. Custom measurements and adjustments include top tube length, seat tube length and angle, head tube length and angle, top tube stand over height, fork rake and relationship to head tube angle for stability or "twitchiness" chain stay length for balance, bottom bracket drop optimized for the type of riding and/or racing you will be doing.





Please Note: Suggested saddle height range is meant to be a guide for finding the right sized bike.  The actual range of saddle height adjustment, once the seatmast length is set, will be about 15mm.
