Hi Swainy – I have the vaguest recollection that it’s always been this way, and for some reason I recall reading it someplace. The +ve only drops a few PSI but it takes a much greater volume of air than the negative.However, Mojo reckon it is probably fine since it’s always dropped the same amount no matter how long I have left it, so I think I’ll ignore it for a while until the service is due.
Sort of related – anyone else notice that in order to hit the correct sag, you need to run pressures a fair bit lower than recommended on the chart. I’m 77kg and find 65 psi in the lefty, and 265+/255- in the Dyad hits the correct sag and feels plush.
I also find I need to reset my Lefty bearings every 3 or 4 rides (TFT reckon this is very normal). It’s a 2 min job so no big deal and TFT tell me it would need done less frequently if I ran the fork stiffer – so a trade off.
