- Show me you new style SLX cranks, preferably 1x setup
So I am running an SLX double and am toying with the idea of going 1×10, narrow/wide and clutch. I don’t want the hassle of swapping out my SLX cranks.
Based on the above thread it seems that 32T is a challenge, however possible with spacers run to offset the ring so the chain misses the tabs (effectively mimicking what RF have done with their 30T).
Has anyone done this and if so what thickness spacers are required?
Also has anyone tried a 33T without spacing (an who makes a 33T narrow/wide ring)?
Finally who aside from RF makes a narrow/wide?
Thanks.Posted 4 years ago
Update. Bit the bullet and went with a 32t RF narrow wide. Set it up tonight with 1.2mm spacers on my SLX double to counteract chain rub on the ring and all seems fine on a round the block spin. Spacers are so narrow that you can’t notice any real aesthetic difference and shifted up and down the cassette without issue. Used the chainring bolts that were already on. Conclusion, it can be done with a 32t on an SLX double with no modification to the spider.Posted 4 years ago
Scandal – no problems so far.
Matter01, I assume you mean the latest SLX double specific crank? If so yes but for 32t ring you will either need to file the tabs slightly to give clearance or use 1.2 mm spacers between the tabs and chainring which is what I am doing with no problems. If going 30t he raceface ring has spacing machined into it.Posted 4 years ago
This guy has a 32T on an SLX double. He ground/filed the inside of the tabs slightly, I spaced mine, but pic shows it can be done.
For spacers I used these. I used 2 x 0.6mm per bolt as was not sure what spacing I would need. So if you are buying you will be fine with 1.2mm. I used the bolts that came with the chainset.Posted 4 years ago
By the way I recommend using double chainring bolts if spacing the ring from the SLX double spider.. I used the bolts that came with the chainset first off and they worked loose really quickly. The longer double bolts fit fine with the spacers and the extra thickness of the narrow wide ring.Posted 4 years ago
Quick update on this with the SLX double cranks. The 1.2mm spacing of the 32T ring shown in the pic above has been increased to 2mm as I found on a particularly wet ride that mud was gathering on the tabs and interfering. 2mm gives much better space for mud clearance, at the same time I decided to slightly bevel the tops of the tabs with a file (on the inside edge) to make sure. No issues since and running nice and quiet. Still not dropped a chain yet either.Posted 4 years ago
Hope I am posting in the right thread… I am currently running an XT rear clutch mech in a 1×10 setup with an SLX M675 crank and narrow-wide 34T chainring:
Rear Derailleur: Shimano XT M786
Crankset: Shimano SLX M675
Cassette: Shimano SLX 11-36
Chainring: Rapide 34T narrow-wide
Everything works fine, I love the 1×10 setup. Am not getting any chainslap on the chainstay although it does swing side-to-side a bit on bumps, though so far that doesn’t seem to be an issue.
I don’t know if I’m just being paranoid, but the completely exposed chainring concerns me in terms of protecting it from knocks, and protecting me from it, so I was thinking of adding a bashguard of some type.
I’ve read this whole thread and others and am still totally confused as to what bashguard will be compatible with this crank and chainring setup. Would something like this Blackspire Defender work? Would you run a 36T bash for a 34T chainring?
Should I be looking at some kind of chain device as well, or is it not really needed with the NW chain and clutch mech combo?
Will appreciate if someone can kindly enlighten me…Posted 3 years ago
