Thats easy, Her on Crests & you on Flows.tmccrohon said:
She will like the weight of the crests & they will hold up to lots under her weight & they are 2mm wider inside the rim than the Arch & only 1.6mm narrower than the Flow.
I'm 177 Lb but was up around 190 & have used Arch & Flows & just find the flows give better control with lower tyre pressures.
The 2.4 Ardent is a great front tyre for the Rip9 but the 2.25 Ardent is crap IMHO
