PoiZoNouZ Posted December 6, 2014 Posted December 6, 2014 There is a great special at evobikes on the FRM 42T cog and 34T chainring combo for R1650 Question 1: Is this a good set for my bike? 2013 Trek Superfly DS changed RD to medium cage Type 2 X0 Question 2: The cassette I have is not compatible as it does not split up, HG62 Shimano, only 11 and 13 are separate.Can I change the cassette with my mates Sram 1050 which does split, straight across? Will they work on the same hub? Answers not on a postcard pls.
flyguysa Posted December 6, 2014 Posted December 6, 2014 Yes.... And order the 16 sprocket to replace 15 and 17.
PoiZoNouZ Posted December 7, 2014 Author Posted December 7, 2014 I forgot to do the 16T sprocket. Will try add on. Does it make a big diff?

SRAM has a nice drivetrain compatibility chart on their website. It says your XO RD is not compatible with a 42t setup at the rear. But some here have managed to sort this out by fitting a longer "b" screw that allows the correct gear-to-jockey clearance to be obtained. You may have to do this mod to get your XO to play nicely with the 42t rear. You may also have to lengthen or shorten (less likely) your chain by a link or two depending how many teeth you add at the rear and remove in the front compared to your current setup.
PoiZoNouZ Posted December 7, 2014 Author Posted December 7, 2014 Getting a new XT chain so will be using that with the setup. Did not see anything about the X0 not playing ball hopefully should be good.

I was wrong my RD is a long cage.
JXV Posted December 8, 2014 Posted December 8, 2014 I don't see a 10 speed 42T cassette on their list at all? I was wrong my RD is a long cage.Yes that's my point. The XO RD is rated for up to 36t. There are other threads here where hubbers have had trouble getting the XO to shift up onto their 42t modified clusters because the cage fouls against the big cog. If you experience this it can be solved very simply by fitting a longer b screw that is used to increase sprocket-to-pulley distance. Good luck with your conversion
PoiZoNouZ Posted December 8, 2014 Author Posted December 8, 2014 Ok I will give it a go. Actually no RD is listed at all for a 42T rear unless its a 1x11 as far as I can tell.
JXV Posted December 8, 2014 Posted December 8, 2014 Do a search for 1x10 threads. Lots of advice from those who have already done it.
LazyTrailRider Posted December 8, 2014 Posted December 8, 2014 In addition to what JXV has said (which is all correct), be aware of the fact that if your current Shimano cassette and your mate's SRAM cassette are at different levels of wear, your current chain may not mesh nicely with it and will skip around. Overall advice: search for 1x10 threads, for example here: https://community.bikehub.co.za/topic/145497-is-going-1x10-really-worth-it/?do=findComment&comment=2490177
PoiZoNouZ Posted December 8, 2014 Author Posted December 8, 2014 Our cassettes are of a similar age, 2500km, both look after our stuff and service and lube regularly. (The bikes not each other ) In any event I'm starting with a brand new XT chain.
Skylark Posted December 11, 2014 Posted December 11, 2014 Just a heads up to anyone wanting to do this, Rapide has a special on at the mo for their 42t cog and NW chainring for R999
Elvis Posted January 9, 2015 Posted January 9, 2015 Ok so here is another question. I just ordered the new XTR M9000 1x11. It has a 11-40 ratio on the cassette. Can I use a Sram xx1 cassette on this?
