Rouxenator Posted October 12, 2015 Posted October 12, 2015 I have been riding 1x10 on my MTB for a year now and it is working out great for me. I have a 11-36t at the back and a 32t NW on the standard Acera crank that came with the bike. So far it has seend 6000+ km of bliss This weekend I did a ride on my road bike and was wondering if I can make it a 1x setup like on my MTB? My roadie has a 12-23t at the back and 30/42/52 FSA triple at the front. After some messing around in Excel I found my current 3x8 setup covers ratios from 1.3 (23t/30t) to 4.3 (12t/52t). If I put a 10 speed 11-36t MTB cassette at the back and a 48t NW at the front I cover that perfectly however that would mean new chain, derailleur and shifter. Sticking with 8 speed and opting for HG41 11-34t at the back gives me 1.4 (34t/48t) to 4.3 (11t/48t) and all I need a the MTB cassette and a 48t NW chain ring. My two questions are : 1) has anyone done this and is it a good idea?2) where can I get a 48t BCD 130 narrow wide chain ring in SA?

Doubt you'll need a NW on a road bike.
Rouxenator Posted October 12, 2015 Author Posted October 12, 2015 Excellent! So it has been done? I found a 48t NW BCD 130mm on eBay but was looking for a local option. Any sources?
Rouxenator Posted October 12, 2015 Author Posted October 12, 2015 Doubt you'll need a NW on a road bike.Makes sense... Cool! I'll give it a try.
Brickleberry Posted October 12, 2015 Posted October 12, 2015 Excellent! So it has been done? I found a 48t NW BCD 130mm on eBay but was looking for a local option. Any sources?Try kitted SA , they on the hub.
Rouxenator Posted October 12, 2015 Author Posted October 12, 2015 Try kitted SA , they on the hub.I like Kitted, I put in order #100 and got it for half price However they only do BCD 104mm for MTB when it comes to NW options.
Maniax Posted October 12, 2015 Posted October 12, 2015 I might be wrong, but wont you need a mtb RD? As far as I know road RD's max out at 32 teeth.
rock Posted October 12, 2015 Posted October 12, 2015 are you running sram? If shimano, you're going to have a flappy brake lever that will just annoy the heck out of me, with sram you can remove the LH gear lever for a clean set up, I did it and there's some tutorials on line, a bit fiddly. Spez have some crit bikes for MY16 that are 1x specific. So its certainly coming! http://i62.tinypic.com/rr2rs4.jpg
Rouxenator Posted October 12, 2015 Author Posted October 12, 2015 I am not sure what the capacity is of the current 8 speed Sora RD. It dates back from 2002 however it has been coping with a 12-23 30/42/52 setup so I am guessing it should be OK with a 11-34 x 42t setup? Otherwise I will need to get a MTB RD. Just ordered the 11-34t 8 speed HG-41 cassette.
rock Posted October 12, 2015 Posted October 12, 2015 FYI Shimano 10sp rear derailleurs are not compatible with 10sp road shifters,
Rouxenator Posted October 12, 2015 Author Posted October 12, 2015 FYI Shimano 10sp rear derailleurs are not compatible with 10sp road shifters,At the moment I am planing to keep everything the same, just change the cassette from 12-23t to a 11-34t and removing the FD along with the 30 and 52 blades.
Maniax Posted October 12, 2015 Posted October 12, 2015 FYI Shimano 10sp rear derailleurs are not compatible with 10sp road shifters,Hmmm.... You sure about that? You probably meant 8sp, to which I agree. 8sp RD isnt compatible with 10 speed shifters.

I doubt it.... For a 32 you need a rd with a longer "arm". I havent seen options for bigger sprockets though...
