I'm going to 1x9 on my Trance, for now at least. Two reasons really. Firstly to see if I can get on with 32 / 11 to 32 before going possibly 1x10. Also just to try to further improve my climbing and make me less lazy.
So plan is to ditch big and little ring, fit a Superstar single speed, bb, chain device ( no iscg mounts), A Hope bash ring and simply ditch front mech and shifter. Will I die ? and will the Superstar device space out far enough to follow chain line if 32 middle ring is still where it was originally ?
Ta! ..and sorry if I haven't searched deep enough to find this out !
Run a 32 ring without shifting pins and cut outs.
You don't need the bash ring so don't fit one.
Enjoy!
Thank you ! Will I need the chain device or do I try it with maybe a shortened chain, so that max length is just pulling the mech as far forward as it would if I was in 44 / 32 ?
Just want to try the set up ideally before I go buying all sorts of "marketing" ! Will save cash where I can, but want it to work, if you get what I mean ?
Which superstar chain device? They won't all work with a bash
I have exactly the same set up on my 456. 32 tooth Blackspire DH chainring with deep teeth, Superstar BB mounted chain guide and an 11-32 cassette.
You could probably just leave the front mech as the chain guide if you wanted to do it on the cheap for now? You don't need the bash.
Guys ! Thanks again. Will run without the bash then, presumably need shorter chainring bolts to fit single ring to Deore cranks? Shorten chain ?.....Off to do some work in a minute, via LBS !
Sorry for confusion. Superstar type chain device and a chainring without cut outs is the best (and cheapest) way to give 1x9 a proper go (no need for a bash ring). Not using a chain device or using a normal cut out chainring is likely to cause the chain to come off and hence for you to get pissed off with it.
For me running 1x9 means more grunting and effort... so the last thing I want is the risk of the chain coming off causing my knees to smack the stem or boll*cks to hit the top bar... 🙁
Chainring bolts can be shortened with a hacksaw/file/grinder or spaced out with washers to give it a whirl.
Messiah ! Thanks for the graphic clarification ! Balls / toptube interface.Bad. 😆
I dont mind grunting from effort, just not from impact.
I've been running 1x9 on my trance for a year now and its been great. never once dropped the chain I'm running an e-13 lg1 guide and e-13 chainring.
Yep shorten chain to up the tension on your single 32t and use shorter bolts or washers to space out if not fitting an outer/bash ring
Are you proposing to use a top only guide or one with a bottom roller, if its a top only version would a seat tube mounted version not cover what you require and save you having to take the BB cup out/allow a tad more easy adjustment? dunno what your frame allows though
Did you have to grind down your inner chainring bolt holes to fit the lg1+?
nope it fits perfect. I'm running xt cranks and a bb adaptor on the lg1 as there are no iscg tabs on the frame. There is about 4mm 5mm between the backplate and the crank granny tabs.
Agreed with the above - spend the money that you were going to splash on a bash guard on a SS specific chainring. The MRP Party Ring I use on my 1x9'd setup on the 'big' bike is light but expensive. The On-One stainless ring on my singlespeed is heavier but after over a year of use shows hardly any wear and was quite cheap.
The Superstar SS device (the BB mount £15ish jobbie) I ran on my old hardtail for about a year and it was faultless. Spend a few months previous to that faffing with front mechs wound out etc and it wasn't worth the pain it caused to be honest.
Great setup though - never find myself wishing I had a granny ring. Greatest acheievement so far was the mega steep vertical climb through the trees on the black at Glentress (the start of the long slog up to the shed). Got up that which I used to struggle with even with a granny ring so it must do something for your fitness...
I run a similar setup which I put together on a budget to try it out on a 120mm stumpy so similar bike to yours.
Superstar BB mount chain device £16, no bashguard required, single ring short bolts £5 from hubjub and a stainless 32t ring £15 from on-one.
Well chuffed with it, saved weight, made room in the cockpit, saves all the crap in the front mech and i've climbed everything at all the trail centres, local xc and peaks without a problem. I'm not even fit - you need a bit of determination to get up some of the peak hills after 30K though.... 😉
