PVD Road Fork

The Fork

The fork will be a steel handmade fork. It will be made so that one of the more popular carbon forks can be put on the bike without screwing up the geometry.

Reynolds, Easton and True Temper are major players in this market.

43mm offset seems to be the favorite these days. Although 40, 44, 45, and 50mm offsets are available

Easton EC90 Forks have 43mm rakes with axle to crown lengths of 365 ± 1mm on curved forks and 364 ± 1mm on straight bladed forks.

Alpha Q forks tend to use 44mm offsets with 371mm axle to crown distances.
Reynolds forks tend to use 372mm axle to crown distances and 43mm offsets.

The fork will be made 372mm x 43mm.

The True Temper steerer of the same length. An 84 gram savings


Crappy mitres made nice with five tacks on each side.




Leaving the cap slightly oversized before fusion welding gives some filler to use.
