Just gone to Lyrik Coil Uturn – the weight isnt at all noticable and the uturn helps on mega steep climbs.
Tested it first with a 2011 Float 36 RL2c thing and they were amazing if you can afford them but they are mega money.
A new set of Lyriks on classifieds at the mo.
Email me if you need to know anymore about my setup at 160mm on a five.
