I'm running a 2.35/2.25 combo on Valor's. I run 21/25 PSI and weigh 145 pounds.

im thinking of the same tyresetup, but not sure about the rim. What do yout think? Will the arch ex with 21mm inner width from my original wheelset from the 2015er FSI be enough for an 2,35 Ardent race? Is it worth to change the rims to the wider Arch MK3 with 26mm inner width?

How many PSI do you drive normaly with the new setup?

Im loving the grip and traktion of an wider tyre with less pressure too.... :thumbup:

Thanks for comments.
I think 21mm internal width would be fine to run 2.35 Ardents on. Of course as I was building a new set of wheels so went for the wider (albeit slightly heavier option). I say give it a go and see what you think. I might try the 2.25 Ardent race just for a comparison later this year but for the time being Im loving this combo. I run 21psi front and 23psi rear and i weigh on average 140lb (63.5kg).

Hi All, I previously had a '16 FSi Carbon 2 then went to a' 17 Scalpel-Si Carbon 3 but sold it recently.

I missed having a Lefty so today I picked up a '16 FSI Black Inc in Medium. Went for a ride before buying and I liked it a lot so bought it.

Specs: ... 803fd54b3f

Upgrades: converted to 1x11 with a 32t front ring, XD freehub on the Chris King hub with an XX1 10-42 Casette, 4iiii power meter, upgraded steered tube and stem, upgraded Di2 battery/controller with Bluetooth, Racing Ralph's in 2.1".

I'm a fat a$$ so I may convert back to 2x11 using single shifter but that would add a bit of weight back.

Weighed it with my super "accurate" fish scale at 19lbs 13oz with my pedals but no bottle cage. I thought it would be a bit leaner but I guess it's not that bad. Not sure what more I could do.

Hello, does anyone know or have a picture of the weight of the FSI standard frame?
Not the Hi-Mod or the new 2019 model...


PS: I searched but only found about the Hi-Mod version.
