No Front Sag Measure for 12s?

[poldar12s]

Any comment on his (OntheThrottle.TV) statement that the front sag shouldn't be measured for ths S?

Also, need clarification how to measure the front sag for S.... front fork dive distance vs. just like the rear. I'm confused now.

??? It's on the interweb so it must be true


You most certainly can set the sag on the front of a telelever bike, and it reacts to minor spring preload adjustments as does any suspension. I do agree, telelever is inherently anti-dive, but ride height and suspension compliance react the same as on a conventional fork to spring rates, damping and pre-load.

There are tons of posts on this board advising correct pre-load

If I set the front Ohlin spring sag to 35mm, the front spring length is much shorter than what manual specifies (184mm for 185lb rider) even I'm 165 lb with gears. I put a 184mm stick and now it measures 184mm almost with the two adj rings.

I recall my previous set up with the font sag to be around 35mm gave me problems for only the tight turns (hard to lean further during the turn). After I changed to the manual spec, it handles like a big bike until I raised the rear to 7 threads. Then all good except the seating position. With the raised rear and 190/55 profile rear tire, I felt more pressure on the perineum (stock seat). I don't remember exactly how many 'mm' raised with the combo but surely my seating was changed. I concern the perineum over the handling for more mileages
