This is a brand new saddle from WTB and we're really impressed with it so far. Unlike most race seats it's short, relatively broad and flat, with a central groove in the 'Thinline' padding and small cross-cut flex zones under your sit bones.
Some folk will find it too square and easy to slide up and down on but there are loads of narrow, swoopy saddles and this is about the only broad, flat, lightweight option around.
The compact shape allows easy exit off either end, which makes the saddle very useful for acrobatic technical riders and it's a great broad platform for protecting your arse on heavy landings. There's no scuff protection on the leather upper so take care of it, but that's true of most very light seats.
