The Arte Selle Dakar Print is a really good race saddle at a very reasonable price.
We reviewed the Arte Selle Dakar Double saddle earlier in the year and liked it a lot. This one is very similar.
The shell is 275mm long and 130mm across; about normal for a saddle of this kind. That plastic shell is carbon-infused and it flexes a little to reduce vibration and smooth over pot-holed roads.
