Thinking about losing the triple chain ring up front when I replace my old transmission in the spring.
Is there a 1 x 10 solution that isn't a bodge of different bits and costs less than £200. Or failing that a place where I can buy a ready made kit?
Had a look but came away a bit confused... which isn't unusual for me.
CRC do them in groupsets but i think if you want narrow wide you end up with various makers on your set up

Yeah I saw them on chain reaction but wasn't sure.
The narrow wide thing sounds the way to go but Shimano don't do that do they?
A lot depends what you are starting with.
Assuming 3x10.
Buy a Narrow wide ring from hope or race face and some short bolts.
Maybe a short or medium cage rear mech with clutch.
Cassette and chain.
If on 9 sped you'll need a shifter too.
I'm just going to replace everything (cranks cassette, shifter, chain, mech). It's all years old and due for retirement.
Was going to replace bit by bit but that usually causes more problems than it solves.
Define "Bodge"?? Plenty of mix 'n max drivetrain stuff works really well! I've got xx1 cranks + 30T Narrow/Wide driving back down a KNC chain into an XTR cassette, with a One up 42T big ring, and an XTR derailleur with Radcage doing the shifty bits. Works perfectly. Substitute some more basic components (SLX etc) and you'd get pretty much the same thing, with just a bit less bling, for your £200ish
Deore triple 9 speed chainset £48 (remove and eBay the chainrings)
Bolt on a Superstar components IO chainring £26
Onza alloy singlespeed chainring bolts £6
Deore shadow plus mech medium cage £28
Zee 10 speed shifter £15
XT 11-36 cassette £32
One-up expander 42t cog and 16t cog £42.50 on eBay
Oneup RAD cage optional but optimum. (£23)
£220.50
You don't actually need the RAD cage, but it's better setup with it on.
Deore triple 9 speed chainset £48 (remove and eBay the chainrings)
OP - have you not got a triple crank already?
yeah I don't think you need 10 speed specific cranks if you are going 1x so keep the original cranks

You could get this even cheaper, ie cheaper NW, poss cheaper mech, poss cheaper cassette, but I like the option chosen. Scapegoats prcing up there is cheaper but I can't find all the things he has listed for the prices he has quoted...
Optional Radr Cage and Extender sprocket adds £96 on to this to give a grand total of 235.45 and you get to bin your front mech forever!!!
Zee Mech
Saint Shifter
RadR cage
OneUp 42t
XT cassette
NW Ring
Chain
Save yourself some cash at the start and keep the cranks, been rocking mine for almost a decade from 3x9 and now 1x10.
Do you think you need a sprocket larger than 36T? A lot of people don't bother (myself included) and as said above it avoids spending up to another £100. You can always just buy an 11-36 XT cassette and if you find it doesn't suit buy the extender cog and cage later.
is there a UK seller of the RAD cage, or is it a US order?
do you really need the clutch mech ? I'm not gnar in any way
I've got a SRAM X7 on my bike and I'm thinking about doing 1x9 on the cheap

You order it from their site (click "International" on the front page.) Pricing and postage is in USD, but mine was despatched from a UK address and arrived in a couple of days.
@Scapegoat - there is really no need to buy new cranks unless they are goosed.

It all depends what cranks he has currently though doesn't it. He hasn't told us.

Scapegoat, thanks, great. Links?
Rather than the One-Up 42T that requires a new mech cage, go with a Hope T-rex 40T and they supply a longer B screw which means you can just use a medium caged mech.
Just get the 1x10 XT bundle from CRC and something like the SLX triple crankset which will include a new BB for £69.49. Sell the SLX rings.
Job. Done.
Choose the 30 tooth chainring option if you need, that way you don't need to worry about RAD cages and extender cogs, etc.
Wow just checked back and surprised to see so much activity.
Thanks for the great responses everyone (especially Scapegoat). I hadn't thought about keeping the cranks, I'll definitely do that. They're old Shimano Hone cranks. I assume that'll be OK.
I'll check out the options later tonight and make a shopping list. I'll post it back here for a quick check in case I do anything stupid but I should be OK given the detailed responses.
Thanks again all.
do you really need the clutch mech ? I'm not gnar in any way
Not IMO. I'm using a Superstar IO ring on my Soul with 9sp XT everything else. Haven't dropped the chain yet in 6 months use.
I've just gone 1x10 on the hardtail, XT mech, shifter and 11-36 cassette. Blackspire NW 32 tooth ring on existing triple cranks with eThirteen shims and a new chain.
No expander cog yet but I have the option if I want to fit one later (and it's been ok so far)

And yes, your Hone cranks are 104 BCD, you just need to remove the granny and outer rings, and swap the middle one for the IO chainring, using the Singlespeed chainring bolts.
Rather than the One-Up 42T that requires a new mech cage, go with a Hope T-rex 40T and they supply a longer B screw which means you can just use a medium caged mech
If you do go this route, the eBay seller has some 40t Oneup cogs, but you need an 11-34 cassette for correct shifting, not 11-36. It will still work better with a RAD cage, according to internet wisdom (and marketing!)

Do you? I've added a hope 40t to my 11-36 on the hardtail and it works perfectly with zee fr mech. No need to even lengthen the chain or adjust the b screw.
I take it all back . I had it in the back of my mind that they didn't work well one way round or the other. A check on Oneup's blurb shows they recommend both for 11-36, and don't mention 11-34, so I'll have to score that one as a miss on my part. It may have been another brand, but someone was selling one on here because the combination didn't shift properly. E thirteen perhaps?
After further thought if i wanted most bang for buck I would.

Right, I've bookmarked the thread and will buy bits as I can afford them over the next couple of months.
Thanks to everyone for their input, a very useful thread for anyone considering the same upgrade.
Jim.
Superstar are the cheapest narrow wide ring and the quality is very good , usually run 34 t never had issues £24.99 good choice of colours
[quote="edhornby"]do you really need the clutch mech ? I'm not gnar in any way

We've both got SRAM 1x9 on our bikes with standard X9 rear mechs but we do both use a bottom chain roller thinger. I've got a Blackspire doofer on my bike which cost about £25 I think and Chris made the one on his bike for about a fiver. Cheap as chips and they both work well 😀 I don't think I'd go without some kind of tensioner on the chain to keep it on the chainring though 😕
