Joshm1991 Posted February 12, 2014 Report Share Posted February 12, 2014 Hey guys! Dunno if you guys know much about these new(ish) chainrings, but what's the restriction on running them? I've heard something about only being able to run even numbers on the rear cassette (like 12, 14, 16 up to whatever top ring you can get.. Like a 40 or something), due to the teeth on the chainring, but I've looked at my new (standard) chainring and the way the dirt has discoloured the teeth, it looks like it could run a narrow-wide without any problems? I dunno if this is the right forum to ask this kinda question on but I know a few of you guys know a fair bit about everything and have helped me out in the past so I though I'd give it a shot! Cheers in advance Joosh Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted February 12, 2014 Report Share Posted February 12, 2014 Don't see how the tooth count makes a difference? The chain links will always alternate the same regardless 1 Quote Link to comment Share on other sites More sharing options...
Joshm1991 Posted February 12, 2014 Author Report Share Posted February 12, 2014 That's what I thought.. But I'm sure MBUK reviewed them, and said you can only run even teeth on the back! I'll have to have another read over it properly to see if I miss read it but that's why I asked! It sounded a bit daft and very limiting to me!

ZeroMatt Posted February 12, 2014 Report Share Posted February 12, 2014 Can't say I've ever heard that about the cassette; it shouldn't make any difference on those. You can't have an odd number of teeth on the chainring though. Quote Link to comment Share on other sites More sharing options...
Joshm1991 Posted February 12, 2014 Author Report Share Posted February 12, 2014 You can't have an odd number of teeth on the chainring though. Yeah I figured that, it was just the cassette that I'd heard the even tooth count thing about! I can't even find the MBUK magazine that had the review in it.. Never mind!

dezmtber Posted February 12, 2014 Report Share Posted February 12, 2014 I have had one since raceface had them in stock a few months back. i found it works best with a short cage clutch or type 2 mech as well i have seen a few people running them on bikes using regular mechs too. you can use any cassette 6,7,8,9,10,11 speed ect any mech will work. (though a cluch or type 2 works better) any chain will work too. Quote Link to comment Share on other sites More sharing options...
forteh Posted February 13, 2014 Report Share Posted February 13, 2014 (edited) Are these available in 5 bolt pattern? If I ditch my mrp system1 (the original one) would I suffer from derailment because I don't have a clutch mech? edit: I have a middleburn 5 bolt spider (using 110mm I guess) so a raceface one should fit, however they don't do smaller than a 38t in 110 - I think I use 36-34 as lowest ratio at the moment and really don't want to go much higher Perhaps I should suck it up and grow bigger legs Edited February 13, 2014 by forteh Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted February 13, 2014 Report Share Posted February 13, 2014 Think a number of small manufacturers do them down to 36t but not seen a 34t one yet. An alternative would be to get a narrow wide spiderless ring for the 'burns. Quote Link to comment Share on other sites More sharing options...
forteh Posted February 13, 2014 Report Share Posted February 13, 2014 (edited) Just checked, my ring is 36t running with an 11-34 cassette. Haven't found any direct fitment narrow-wide rings for the middleburn spline Have shot an email over to middleburn to see if they intend to do narrow-wide rings. Edit: I could always get a 104 spider for the burns but that's an extra 50 quid! Edited February 13, 2014 by forteh Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted February 13, 2014 Report Share Posted February 13, 2014 Last I heard from Matt at Middleburn he said they were a possibility but would only do them for the X-Type ones. I've seen some narrow-wide rings with the middleburn spline made by Wolf Tooth; however, there aren't any currently available on their site. May be worth shooting them an email?

forteh Posted February 14, 2014 Report Share Posted February 14, 2014 Emailed Wolf Tooth this morning, came back to me saying that they will be making some more in the summer Once the wedding is out of the way I will invest in a clutch mech and new ring up front.

isitafox Posted May 28, 2014 Report Share Posted May 28, 2014 Sorted a dirt cheap xt clutch mech and some deore hollowtech 2's so need to order a chainring I'm just stuck on how many teeth to go for. I think the biggest sprocket I can run is a 36t so I'm stuck between a 32 and 34? Quote Link to comment Share on other sites More sharing options...
forteh Posted May 28, 2014 Report Share Posted May 28, 2014 My dropstop ring arrived from wolf tooth today, it's a lovely bit of kit, really well made and fits a treat. By ditching the middleburn spider, blackspire ring and mrp system1 chain guide the bike has shed best part of a pound! Should be about 28.7 pounds now 1 Quote Link to comment Share on other sites More sharing options...

I think the biggest sprocket I can run is a 36t so I'm stuck between a 32 and 34? What cassette have you got? I find that 32-34 works really well round cannock chase and don't struggle with any of the climbs there, that said they're not exactly hardcore climbs and the intense climbs like a goat. Go for a ride and see how you get on with the middle ring only on the biggest climbs you frequent, you can always go up to a 36t cassette if need be. Wolf tooth recommend that you run a 10 speed chain with their rings to improve retention, not sure on the other manufacturers but I believe they're all designed to be run 10x1 so will be machined to sit the narrower chain. Something to potentially factor in if you're switching. Quote Link to comment Share on other sites More sharing options...
isitafox Posted May 28, 2014 Report Share Posted May 28, 2014 Not got a cassette yet but I'll probably get a 36/11 10 speed. Probably stick to 34 up front then, cheers! Quote Link to comment Share on other sites More sharing options...
forteh Posted May 28, 2014 Report Share Posted May 28, 2014 I would be tempted to go with 32-36, give you some respite on longer climbs. I stuck with 32-34 because it's what I'm used to now, however there was a massive improvement in climbing going to the 34 cassette, particularly on the longer climbs. My climbing style is fast but not particularly long lived, with 32-34 I'm forced to ride up hills quickly in order to keep pedal cadence up enough to be efficient. Ask Paul Oliver ( Curtis rider ) or Tom booth about my climbing style The 1/3rd mile 1:10 up cannock chase is quite doable with my current gearing but my lungs know about it by about 2/3rds of the way up! 1 Quote Link to comment Share on other sites More sharing options...

forteh Posted May 28, 2014 Report Share Posted May 28, 2014 (edited) How are you finding the chain line with the x-type offset ring on isis/sq taper arms? The chainline is actually a fair bit better than it was before :$ Before it was where ever the middle ring was on the 110mm xc spider (the mrp took up the outside ring position) and that put the chainline about straight on 6-7 on the block. I guess it's probably about 10mm inboard now and sitting straight on 3-4ish which is where more torque is put in. When I first got it out the packet I was a bit suprised by the amount of dish but it's worked out really well. For reference I'm using a 121mm x73 hope ti square taper bb in a 68mm shell so the drive side cup sticks out a bit further than intended but it works fine. The inside face of the cranks are within 1-2mm of the BB cups, looks like an external set up edit: weighed the bike today, 13.067kg - 28.75lbs - not bad I don't think for an elderly intense 5.5 Edited May 30, 2014 by forteh Quote Link to comment Share on other sites More sharing options...
