ISM PN 3.0

For me it was love at first sit, thought certainly not at first sight: I had avoided ISM saddles for years because I didn't like the look of them. Now I couldn't go back to using a traditional saddle on a TT bike.

Where has the ISM PN 3.0 been all our time-trialling life? The new PN (‘performance narrow’) range offers better thigh and hamstring clearance than earlier versions thanks to a narrower ‘nose’. For us it was love at first sit.

If you haven't tried a split-nose saddle before, the way it works is the lower you get on the tri-bars the better the ISM feels (whereas a conventional saddle feels progressively more uncomfortable as pressure on the soft-tissue area increases) allowing you to stay anchored in your aero position – and it works for men and women.
