Seatpost is 31.6, bottom bracket shell is 73mm english. Headset depends on the forks
Edit - Use carbon paste for the seatpost such as finish line fibre grip
Thanks, what type of front derailleur do I need to get for a c456 frame (going 2x10) as this bike will get used on the road as well on the trails.
And thanks all for the comments and help ! Much appreciated.
Like others, 140mm forks. Also run a 2 degree slackset, which is great.
Yellow looks great and I'd love one, but they chip too easily and will probably look a mess in no time unless you stay precious with it, hence plain black for me with the 456. My compromise was a yellow whippet as my xc mince/canal commuter/exercise bike which doesn't get thrown around and never ends up under a pile of bikes in the backs of peoples cars.

Definitely this! I have a KS dropper seized in mine which has just failed rendering the bike useless 🙁
Seized seatpost in a C456 is a bloody nightmare. I was almost looking at writing off the post having to cut it (thankfully not a dropper at the time). Took ages, with a lot of various tools and chemicals and swearing. Eventually shifted with some ski/snowboard base cleaner. Basically a citric based liquid. Then when it started turning the noise was immense. Sure my neighbours though I was killing someone.
Post once removed was heavily pitted with corrosion. That's carbon + alloy for you.
Anyway, carbon paste always. Plus I've seen some seatpost manufacturers recommend it for alloy posts regardless of the frame material.
Stuff I've got is DS7000 Base Cleaner. Picked it up in a shop somewhere but not sure where. Might have even been in the US.
They have a site - http://demonsnow.com/store/DS%207000%20Base%20Cleaner
It's basically citric acid and stuff.
Hi all
Looking to get a Hope headset for the c456 frame and am completely stumped as to which pick & mix hope headset will fit the frame ? I have a set of tapered Rockshox LYRICS for the frame.
There are a lot of options for the headset on CRC. Even filtering on 1 1/8 didn't help.
Apologies if this is a real newby question and should be blindingly obvious.
Thanks
Just get the Work's one from On-one, you'll probably want one at some point anyway 😉
Mine, a few grams under 24Lbs with pedals & a bit of mud, but with U-turn Reba's, no dropper post & carbon crank's with ceramic BB, I think it will be my go to bike this year 🙂

Is this a headset ? Better than a Hope one?
Aha it's a slackset headset by works on one, but I cannot see a version for tapered forks ?
They even state In the description "Note:- This model will only work with straight, NOT tapered steerer forks. A taper steerer model is in development."
Mine above is running a Work's one for tapered steerer, try their website or call OO to confirm.
Cheers.
For hope and a tapered steerer I am pretty sure you want the number 2 top cup and F bottom. Check the dimensions here:
Wouldn't mind getting a works slackset for mine but running a tapered carbon steerer which has a long taper section on a 16" frame with the short head tube probably makes it a difficult one sort.
Ok, really stooped question, don't suppose there is any chance that the c456 can take a 1.5 straight steerer ?
It might well do if you use an external 44mm top cup. Just need to check there is enough depth to fit the cup in.
Actually yes, the top cup I have from on one to extend the head tube for tapered forks is basically a 44mm top cup but with a top cover and split ring to reduce it down to a 1 1/8th steerer like you get with a reducer crown race. 1.5" steerer will fit through the bearing and I can use the top cap I took off my cannondale to fit a 1.5" straight fork.

Oh well, too late now, but had the option of RS Lyrics 1.5 straight steerer, but managed to switch to a tapered set as I thought the 1.5 straight set wouldn't fit. They were a lot less money too.
Anyhow, what does this on one works slack set do, that makes it worth doing ?
Slackens the head angle, check out the [url= http://www.workscomponents.co.uk/ ]website[/url]
Wow, just been to the http://www.workscomponents.co.uk and more headset choices than I can shake a stick at !
£80 for a headset !
Wouldn't be able to figure out which option I needed, apart from tapered forks !
£80 is probably not much more than a Hope one I'd imagine, call them & tell them which frame & they will take your money 😀

Sigh, isn't that the truth, but what does the works 1,1.5,2 degree headset do ? I've looked round their site and cannot fathom what the difference is ?
I understand that it slackens the head angle - does that quicken the steering ?
Will a 650 rear wheel fit in this frame or the EVO version?
Apparently 650 will fit, not sure about how big a tyre you can go though.
Enjoying mine, 11kg (24 1/4 lb) dead on with Thor AM 140 (on the fly 100-140 adjust) fork, Hope spiderless crankset 1x10 with Zee mech and shifter, XT brakes, Pro2 evo on Arch EX and a Reverb. I'm tempted to try it with a standard post and a Reba to see if it would get any nearer to 10kg and still ride well. The current setup is probably more or less how it was originally envisaged. Dropping the fork to 100 for climbs makes a hell of a lot of sense. After buggering around with various combinations of headset I ended up using the fitted smoothie from On One, if nothing else because of the reported nightmare of trying to remove the bottom cup.
Scapegoat, what wheels/ tyres are you running? At only a 1/4lb more than me running pretty much the lightest stuff I could get bar the forks I'm quite surprised at your weight.
Nobby Nic tubeless on Arch Ex. Are you including pedals?
Yes, but with lighter forks, no dropper just about the lightest crank/ BB combo available I would of thought the difference to be nearer a couple of lbs.
Full spec,
Large frame
Xt 1x 10'with zee rear mech
Xt brakes
Iodine 3 wheels fat Albert tubeless tyres
Reba 100/130 u-turn forks
fsa carbon cranks with ceramic bb
Superstar pedals
Thomson stem & post, WTB saddle.
Carbon fat boy light bars esi grips.
650 rear will fit but you would want to run a slackset to get the BB height back down and a matching 650 front and fork (obviously).
I was looking at my regular C456 at the weekend thinking there is probably enough room to make some new rear dropouts to move the rear wheel up and slightly forward but it won't be easy due to the design of the chain/seat stay interface. I didn't know they now did a slackset option for the tapered steerers.
Well, I've just weighed mine again. Without pedals it's 11 kg. Add 500g for Nano Thrupins, or 400g for XT trail
Full build: 18" C456, on one Smoothie mixer. On One Knuckleball carbon bars and SRAM foam lock-ons, Superstar Zephir 50mm stem.
Hope spiderless cranks and BB, 32t chainring, Zee mech with Radr cage, XT 11-42 (One-Up), KMC chain. Zee shifter, XT brakes.
Magura AM140 fork. Wheels are Hope Pro 2 Evo on Arch EX, 2.2 Nics, tubeless.
Seatpost is a Reverb 125x420 and the saddle is a Charge Spoon.
Having checked various specs, your Reba is only about 100g lighter than the Thor, which is billed at about 1770g. The wheelset is going to be very similar, and the tyres much the same weight. So, by the time I add the Nanos onto mine it weighs 11.5 kg, or 25 1/3lb. If that is 750g heavier than yours it makes sense. The extra weight of my Reverb and cranks, the odd 100 or so grammes from the tyres and fork compared with your setup would be the main difference.

Thanks andyl, reckon I'll get these today as they are reduced at CRC and TBH not really sure I get what the works components headset will do over the Hope version.
Before I go nuts on CRC - could I just confirm here with the STW experts that I'm getting the right Hope bottom cup for a c456 frame for tapered steered forks.
This is the current bottom hope pick & mix headset on the frame :
Item Name: Hope Pick n Mix Headset Bottom Cup
Product Code: XXS8350
Item ID: 186006
Item Description:
Item Style: Type: D STEPDOWN TRAD 49.57 L/S
Do I need the F bottom cup to replace this or another integrated bottom cup - which I can't see TBH ?
Just want to check before I go on a bike bits shopping spree !
Thanks
Hi STW gurus
Looking to get my last batch of parts - what type of front mech do I need for the c456?
Is is a top clamp ?
Thanks
Hi ade9933
Do you still have the frame ?
Could be interested. E-mail profile.
