I have never got on with the Caterham (Luke) harness / Tillet seat combination as the pull-down lap belt adjusters were a pain to use, so after much research on here and elsewhere, I bit the bullet this weekend and bought a set of Schroth ASM 4 points (pull-up adjusters) with the anti-submarine mechanism built into the shoulder strap.
While I was in a rare spending mood, I decided to go belt and braces and also get the crutch straps as they seemed a reasonable price.
So tonight I took the seat out and fitted the Schroths and they are a marked improvement in terms of ease of use.
I have, as others seem to have done, bolted the locating eyes for the crutch straps to the original rear seat mounts. Straps then routed under the seat and exiting though the centre hole in the seat base.
My problem is that even adjusted to full extension on all 4 adjusters on the straps, they are still too short by around 75mm, when my seat is in the correct position.
Has anyone come across this before or is there an alternative place to locate the crutch strap mounts, ahead of the seat mounts I have used???
