sounds like a bit of a bodge job that Brant.......bit like them 29'' chumba's of old........
I can quite imagine that some people will be upset at trimming parts, even unused parts, off their front mechs.
I've calmed down now Brant :-/. This is my 3rd frame from you guys and I was just initially peeved. I'll just have to fork out in a new top swing mech. The wife won't be happy though.
The frame does look lovely. Really neat welds and lovely detail around the dropouts and brake mount.
Are you getting in any 120mm forks anytime soon?

To be honest, I'm not happy either, because of the way we're getting stuff in, and out, so fast, without us giving you guys the heads up on stuff. I'm going to try and put a stop to it and with new stuff like the El Guapo 29 I'll airfreight and do a proper check over sheet so that it's all clear.
These came in sea freight, I didn't see final production before you did!
And the decals were late.
I'm sorry about the front mech and if we can help with pricing, then I will do. I've got my bestest mountainbike mechanic on it tommorow, going through front mechs to check what's good. Giving advice.
So I'm sorry.
Though personally I'd 1x10 it 🙂

We will be offering complete builds - we're just putting a spec to order together - but due to the oddities of component supply it might well be full builds or nothing. We'll see.
Okaydokay. So decals will be available?
Decals are in now I think and I will make sure they go out to those that have bought.
That looks very, very nice bigdugs
What size frame is that bigdug?
Decal free for Ti is better, no need to spend a few hours stripping them off now. Result!
That looks SWEET. Yep no decals going on mine either. The metal head badge would be nice tho. Mine should come today.
I'm assuming the SLX/XT 3x9 from my Ragley won't work, which is a pain cos things are too steep around here for 1x9. Looking forward to clear guidance.
From what Brant said, it looks like we're the ones who will be giving guidance!
Agree, all you need on a Ti frame is the headtube badge.
I think the clearance issue is just about the front mech, so you should be good with 3x9, it just necessitates grinding off the extra hardware that's not required on a specific mech that fits.
Jon who's posted here, did it to his X9 front mech on his Yelli, to allow him to run 2.4's no problem, but agreed, grinding off parts, (if you have the specific mech that fits in the first place), is not ideal...
Our Neil should be in workshop in 5mins cracking on with this.
Sorry for hopelessness.
You have to fettle a front mech on the DW five spot. Hacksaw, file paint - Simples.
There might be a few teething problems Brant, but the speed of response is pretty impressive IMO - Hats off for customer service sir.
Not hopelessness, but good to have you (and Neil?) here to answer directly.
If it's not alright, it's not the end, 'cos we all know it'll be right in the end...

Agreed but with lots of short chainstay 29ers coming out it would be good if SRAM, Shimano came up with some lower profile mechs??
Yep Clink, that's the real solution!
To be fair I think the majority of frames in the Evo genre were intended to be run with a single front ring and the use of 2 * and 3* chainsets was an option rather than what they wre designed around.
CRC's evergreen sale hastop swing front mechs from £7.49 for an old LX, £12.99 for Deore and £14.99 for XT buy all three and see what fits best and send the other 2 back

Looks nicer without decals
Here's the mod you need to do....:

And yes it hurts!
I believe the front mech modification is the same that Cy recommends / has to do for the Solaris.
1x10 is really the best way to go 🙂
Tomaso, I've got an old LX 9sp mech on which works, so I'm guesing most Shimano bottom swing mechs will fit...
The fact that Brant's on here sorting out problems and giving advice is appreciated. It's one of the reasons I go back to On One for frames (well that and the way they ride).
Thanks.
Everyone who is constructively contributing to this thread is entitled to three free pints from me in Old Gate in Hebden Bridge whenever you want.

Bottom swing ... as in conventional? Happy to have a go hacking at mine if need be. I have an FDM661, an X9 and an old XT available ... all conventional bottom swing. Also have a Dremel I've never used 🙂
Edit: thanks Stoner ... even I can do that mod.

I don't think I'm buying a Fireline (not what I want at the mo) but the above makes it much more likely I'll buy an On One in the future.

There you go. Really chaps, do you need a front mech? Take your triple crankset, put a nice SS chainring in the middle (hard wearing, deep teeth, no shifting ramps etc etc), and drop the mech, shifters and cabling. And free up the bit of your brain that does front shifting and devote it to enjoying your ride.
And thats the front mech mod required for the newer Turner Sultan 29ers, so sounds like quite a common issue, not peculiar to On One?
To be fair, it's the fault of Shimano for being lazy with their front mech production 😆
Edit: Actually, thinking about it, I would say that the number of bikes frames/designs with this issue highlights that Shimano need to be listening to users / manufacturers and responding to demand. There is clearly a design / compatibility issue with their current cost saving design and the market has changed and they need to be listening and adapting.
This talk of 1x10 is all very well, but is very dependent on where you live and ride. I live in Highland and and my bread and butter ride is a 1500 foot climb up Cnoc Fyrish from my house. I would definitely be off pushing much of the ascent on a 29er with only a 32t up front and even 36 on the rear. That's not what I want from my main HT.
XX1 may be the panacea, but I can't justify the cost.
great thread 🙂
Metalheart and Stoner - thanks those pics are useful. My old non-dual-pull LX mech fits, so yes, perhaps Shimano need to revisit their design and go back to top and bottom-pull specific mechs, given the rise in popularity of 29ers? Would prob put the price of mechs up though unfortunately...
So are we saying that you have to hack a mech up and run a 2.1 tyre and not go out in the mud....
Please don't respond with 'go 1 x 10' as it simply doesn't work for the vast majority of people for the bulk of their riding.
Actual clarity on the front mech issue is what i'm looking for, Brant i am happy to buy you 3 pints to find out if this frame is right for me. Plus I could go riding for a couple of days... ummm... barman!
Please don't respond with 'go 1 x 10' as it simply doesn't work for the vast majority of people for the bulk of their riding.
Dunno about that mate. 1x10 with a 32T front sprocket really is pretty steep climbing gearing on an MTB?
So are we saying that you have to hack a mech up and run a 2.1 tyre and not go out in the mud....
Not sure where the 2.1 tyre only and not going out in the mud comes from??? No the consensus seems to be if you want a short chainstay 29er then be prepared to compromise, otherwise go out and buy a long chainstay Ti29er such as a Salsa Mariachi ti or a Lynskey for twice the price 🙄
EDIT and in anycase wont a top swing/low clamp work better here as it moves the clamp below the point where the tyre is closest to the seat tube
Andy, no the top swing mech has the pivot mechanisms and cable clamp sitting behind the seat tube and above the level of the clamp, right where the tyre clearance is at its minimum. Conventional top clamp/bottom swing mechs have all of this more to the side. This is certainly the case on all the Shimano mech's I have to hand.
Ah fair enough 😀
People have been cutting up down-swing FDs like that for a long time, seems a sensible mod.
they already do - the newer direct-mount FDs with the modified cage shape. But direct mount frame fittings look can ugly / be unnecessary for 1x set ups, I like the trimmed down-swing mech option. Jones bikes have been built up that way for ages, there's not a lot of mud room on mine with a std top-swing mech and that has a curved ST and stays over 435mm.There is clearly a design / compatibility issue with their current cost saving design and the market has changed and they need to be listening and adapting.
News from Neil:-
[i]"X9 2x10 fits a treat, plenty of clearance, no mod needed! Top clamp, bottom swing.
X0 and XX are the same so will be fine, not sure about X7 as they have a bulkier clamp design as opposed to the nice neat steel band."
[/i]
Picture coming shortly.

Any way of testing X7 ... there's a groupset I'd buy in the classifieds if I knew it would work.
attaboy two-wheeled dialing diabolists, this thread is coming alive and up from 6 faltering pages to 8 in just 18 hours, but more importantly, full of useful/decent info that will have us riding our fireline evo's this weekend or, depending on delivery, pre-xmas... Keep the relevant gen coming!
some built-up pics and riders' thoughts would be great ...(don't just say "It's good", say why).
There's actually a bit you can cut off those X9/XO (and X7) mechs that would give even more clearance too. Neil says no point. I would though.
Pic... Hang on.
Typical, dont think i will be riding mine tomorrow, i seem to have picked something up that has turned me into a turd factory and rendering me unable to sit down 😯
[i] turned me into a turd factory and rendering me unable to sit down[/i]
tuck your trousers into your socks would be my advice.
Containment is key under these circumstances.
Where's the pics bigdugsbaws ... of the bike not the turds. Missus has conformed mine has arrived at home ... I'm in Dingwall about to hit the drink tho.
