really?
Yup. Riding one right now. It's only 3mm each way.

I've heard of fs manufacturers approving this but never tried it on a fs.

This one takes 3.0 rear tire, chainstays are 440mm instead of 430, and I notice the rear brake it's flat mount like a road frame... there are adaptors for post mount 140mm or 160mm, I assume this flat mount is for 140mm, but I´m not 100% sure of that...

I prefer the workswell, but this one it's already available and I assume the workswell will be a tiny bit more expensive.

I was thingking of buying a canyon or a santacruz, but I hate to pay so much more for just a chinese made hardtail...
Do you have a link or a shop name?

I don't really want to advertise these sellers with a link, talk with them by aliexpress message, not the best customer service at all. But just search for 29 carbon frame boost in aliexpress and you'll get it. Other chinese sellers are much better in communication. Frame looks ok, but not much more. 10mm longer chainstays... I rather wait for the workswell or get a canyon or santacruz highball.

I would not try that, although, it's just 6mm total, 3mm on each size. A frame could easily be designed with dropouts on a central position per side, then just flex 1.5mm inwards or outwards to fit each hub size. 1.5mm lateral flex is no big deal at all. 3mm though... Done it with cheap steel frames few times but with a brand new carbon frame, better not.

Do you have any rationale as to why you would not try it or are you just scared of the unknown? I've been there, done that. It's really fine.

Well, I have a 26er with a 135mm QR my dear. Done it several times with old steel bikes. Thing is, why would I want to be so damn stupid to spend between 3000 to 6000€ in a bike that I´m gonna have to flex it as if it was a 60€ second hand steel bike from the eighties? I´m stupid, but not that that stupid. No relation to scared of the unknown, just not stupid enough. Seen photos of quite a few canyon exceed cfx, broken seatstays with the stock rear hub, so go figure if you flex the chainstays to fit a boost hub there.

You are looking for a open mold frame. What is all this talk about a 6000 euro bike? But if you want to make the search harder on yourself then go ahead.

Hi,

Anyone know what fork travel either the HF or WW are optimised for?

I've got my 100mm travel SID's for XC, but unless I'm reading things wrong, most of these frames are optimised for a 120mm travel fork.

Thanks,

All this xc frames are built over 100mm travel forks. the rake of the fork, that's another story, most brands are now tweaking that, and will also depend of the headset behaviour you want, or taking curves behaviour, also will depend on the head angle...
