Use this saddle on my road and my gravel bike. I came from the Fizik Aliante and the shape of the Fabric Line Race Shallow seems to suit me better. Now I can ride for more than an hour without numbness setting in...more like all day. Fabric could charge 2x as much for this saddle and it would still be a great deal.
Fabric makes a nice saddle. This one is pretty firm. I have a leg length discrepancy and have always had trouble with saddles. A rounded profile without a channel helps. I have been using a very comfortable 1989 Selle Italia Flite Titanium that I bought new. Thought I'd try something more modern but I ended up returning this.
Not as wide as other Fabric saddles, so less chance chaffing thighs. Good amount of side to side curvature. Cushioning is medium firm. Center channel does not extend full length of saddle and compared to other brands is less prominent. Seems well made. Not going into comfort or how it feels as that is unique to each rider.
Seat is comfortable, provides good support. Exterior fabric is grippy thus providing good traction while downhilling however hard to make small changes to your seating position. Overall great saddle, great price.
