As someone has highlighted it looks as though my granny ring is buggered....so for the cost i'm going to look at a single ring setup.

Flicking through MBR this issue they are converting 1x10 but say 1x9 you would need a full chain guide.

I'm looking at using a raceface narrow wide 32t (would ideally want 30t but can't find one anywhere)

Thanks

    Do I need to use a guide with the raceface ring? I don't see how 1x9 would need a guide and 1x10 not need one.

    The problem is the rear mech. no 9spd clutch types.

    How does the clutch mech make a difference? You don't run them with 2x9 or 2x10 for that matter. I'm guessing it just keeps the chain taught?

    Pretty much and you do run a chain guide with 2x9/10 etc. But it's called a front mech.

    The clutch mechs stop the chain detensioning under it's own weight over rough surfaces (when you get chain slap on the chainstay)......

    So the general jist is I will need at least a top guide with 1x9 to help prevent it jumping off....which means the extra cash for the narrow wide ring isn't worth it for a 1x9 setup? I may as well go for the normal raceface single ring at almost half the price.

    and you will most likely need a bottom roller as well.

    I run a 1x9 and use a full chain guide, bought a Superstar Plasma when they were on offer last week for £38. Hadn't really considered not having one or only using just the upper guide or lower roller by itself. I much prefer knowing that the chain will definitely stay in place rather than running the potential risk with an expensive chainring.

    Also surely you would be spinning a lot with a 30t chainring? even a 32t would be pretty low. I personally run a 36t but I assume you live in a very 'hilly' area and expect to do a lot of climbing?

    I currently run 24/38 and struggle on some climbs without using the 24 so I was looking for a middle ground but without trialling different ring sizes I don't know what will be best.

    I can't make my mind up whether to just replace both rings and keep the double, or go single and a guide.

    Both are going to be much of a muchness price wise i think.

    You can go 1x9 with dual ring chain guides quite cheaply, mine cost me about £35 (some pics in the top link in my sig)
    1/ Used but nearly new E13 chainring
    2/ Used ally bash
    3/ Piece of carbon fibre I cut to fit the granny tabs to act as an inner chain guide.

    Or you can use an n-gear jump stop (about £8) a bash as the outer and a lower such as a Stinger which is what my daughter uses.

  • Hey I just tested my narrow wide at cyb yesterday 38T version on a 1x9 slx standard derailleur on an anthem, did a mix of mbr and some of the enduro route, had one chain drop and we were hammering it(my mate dropped his chain in the same place on a 2x10) the previous ride so it was pretty secure to be fair, I've got a top guide that I'll throw on at some point, I was in the smallest cog at the time so shifting up a gear or two would have kept the chain tight enough to stay on.
    With the size I nearly went 36T but I'm really glad I didn't because I saved just over 500g in weight-its x4 spec shifters/front derailleur so factor that In if your regular places aren't too hilly otherwise you'll reach top end fast :-)
  • I run an MRP 1x chain guide with my 1x9 setup. I'm using my SLX crank and middle ring and haven't dropped the chain once.

    I decided to give it a go. I've ordered a 32t works components narrow/wide and a superstar xcr top guide.
