Just did my first ride on the sector 28s. TBH I found them a hard ride , running 80 psi . I've come off vittoria open pave 25s with latex tubes running at 80f 85r .
I will try dropping them to 75psi and see how they feel , but was very disappointed yesterday.
What are others running at ?
I'm 67kg

I think the best is follow the information on the package from Hutchinson but otherwise I suggest 67/10-1=5,5bar and 5bar (front) :wink:

You should try lowering the pressure than previously with the Vittoria as the 28c should have bigger volume.

Do u remember how many strokes to pump your Vittoria? Try that same no of strokes for the 28c.

80psi is way too high for a 28mm tubeless. Try 60psi. Experiment! There's no pinch flats to worry about, you can run really low pressure in tubeless if you want to.

Hi and thanks for replies,
Yes I am going to play with pressures (got a gauge coming) on next ride out . I know a little makes a big difference, and I did wonder as riding about relationship of volume to pressure .

Didn't want to alter anything yesterday as didn't want them to unseal as the front had been leaking Day before on mounting. So a soapy water remount seemed to sort it , no pressure drop in the morning .

Looking forward to a better ride

I wouldn't be afraid to go under 60psi at 67kg as long as the rims are suitably wide. I run 60-65psi in my Pro Ones 25mm but on really wide rims (21mm internal) at 72kg.
