can’t see the point of a single ring for anything but a DH, 4X or Jump bike
or a trail bike used on rocky stuff where the chain bounces off lots?
the weight difference is marginal at best
front xt shifter, cable and outer, front mech, xtr granny ring, straitline bash = 510g
e13lg1+ = 200g so nearly 3/4lb saved,
mrp1x = 58g so 1lb saved.
its not for everyone but there are benefits to setting your bike up this way. i love not having to coast after rocky stuff now ive fitted a chain device. no matter how tight i ran the chain or what bash and dual guide i tried it just didnt work. good for a bit of extra leg strength too, especially if you tend ot ride shorter distances over the winter; it encourages you to attack climbs a bit more.
i will be refitting my granny for the alps next year though!
