Like messiah, I love mine, wouldn’t be without it and anywhere with proper climbs, I don’t think single ring will do. Widespread signle ring has been around for years, 36 is no bloody different to 34, if you can drag 32/34/36/38 fronts with a 34 you can with a 36.
I also run a short cate saint and 11-27 rear block, lighter, close ratio.
If you compare it to the same spread of gears you have to compare a double/bash/chain guide/long cage mech/wide cassette and the weight differences become fairly small, 150g or so my 11-27 cassette is 130g, even XX 10spd is 208g and their stoooopid money, STD XT is nearer 400 11-36, that’s a lot of weight for a reduced spread.
Then you have the instant change, awesome coming over crests or out of hollows 🙂
They are also bullet proof and a piece of piss to service with massive ground clearance. I think the drag is very minimal, less than a super tacky reear 😉
Unless your a total weight weenie you’ll love it and €200 is very cheap for a €650 crank 🙂
