Hey I'm building a new yeti 575 and I'm looking in to the gearing, 1x10 2x10 3x10? My mate loves his 1x10 set up and reckons I should do that too? My question is, is 1x10 any good for an all round bike for all day rides up and downhills or should I just go with my idea or the 3x10? Opinions please! Thanks Rob
