Fitting R100 GS forks from a paralever model into a ST or G/S frame is relatively straightforward. The steering stem, tapered bearings are the same. The steering stops all line up. I wanted to use my R80G/S wheel and found that drawings exist on the interweb for a custom front axle that fits the larger diameter of the lower fork legs but matches the smaller bearing size of the older wheel. Suitable spacers are included in the drawings though I found out that they are shown the wrong way round.
I’ve used a standard R100GS front calliper as the ST one is fitted to the rear of the leg not the front on the new forks.
I had already used Magura off road master cylinder and a custom hose from Venhill which was just long enough.
Here are some pics. I haven’t ridden it yet but the look is much more purposeful and just what I was looking for.
