[Closed] OMG Going from 20mm thro forks back to 9mm QR - X Lite 15mm axle carbon rigids

my ss is a bit of a winter mincer so I don't need much stiffness

(sorry, haven't used the x-lite but would consider it just for the prevention of the axle slipping out)

Axle slipping out? Not once in 34 years or riding have I had an axle slip out. Lame excuse for a new set of forks. Get them cause they look good :O)

I've got some of those X-Lites. very light. they 'feel' good quality when you're riding. not sure about the stiffness although I expect they're stiffer than the QR equivalent. I think.

I agree, it is unlikely but tell that to the geezer who bust his neck
One of my mates had a new fork fairly recently that just wouldn't seem to take a "set" form his QR and the axle worked loose repeatedly on about the 1st half dozen rides he did. Can't remember if it settled or he bought a new skewer or what but we were talking about strapping the QR and the bolt up with rubber bands at first

I don't maintain my ss bike hardly at all and wouldn't notice a loosening until it was very obvious - If I'd been offered a through axle option when I bought the fork I'd definitely have had it

A lightweight carbon fork is going to be flexier than whatever burly trail forks (Revs?) your 456 has, regardless of what axle it has in it. A thru-axle one might be less twisty but it'll still flex in every other direction.

it's fairly terrifying to watch mine in action, under braking they bend back under the bike like they're preparing to fire the wheel over a castle wall. But it works really well, takes the edge off things.

The axle isn't going anywhere. It just feels flexy in comparison.

Anyway Tim......you know I don't need an excuse to buy new bits 😀

The forks were QR Revs so a reasonable comparison

I have just had built this time a Curtis SS wi Xlite 15mm's and can report for a heavy (17st) bloke the only thing that bothers me is the chatter flex from the dropout area on them, apart from that they are of similar but just touch in hand heapftier than the niner 15mm's which I have not had chance to ride on yet.

Cannot report of even a short term use or ride report as I have only had chance to ride the SS once since my broken bits but can report they are the shizzle for £153 posted brand new even if parcel force inbred decided to open the dropout end part of box and deliver them to me opened. No damage to them as checked whatsoever.

Those whom cringe at the durability of carbon should know that I have ridden pace rc31's older model quite happily at my weight with no problemo at all and that was qr 9mm axle.

15mm make life easier I guess and deffo for security or safety matters.
Performance or stiffness wise 15mm do help but would of course prefer 20mm as you never know what 'core obstacles you'll find down cra nham way.

Could be anything typical of a fallen tree to a fridge to a car battery or possibly a dildo or perhaps a cooow!

Niner's of frame fork etc are of course way overpriced but are lurvely light, when I say luverly light, I mean " I simply doont believe it" light.

Fnish is second to none and features are spot on like tapered steerer and post mount for the brake unlike the X lite which is I.S. as per picture.

This did bother me before buying as I know PM or radial as I know it on my mbike is paramount to an efficient working brake imho.

Apart from having i.s. mount and no option of tapered steerer, and even at £190 odd at crc price from £300 makes them still a killer deal.

Get on it!
Just inform crc that if they were to use a courier next time or choose a contract with a couriering service then get so whi doesn't want to steal the customer's kit never mind damaging it!!!

ENJOI

Are you comparing same model year? Lots of variations in Revelations, comparing a current model QR rev with a 426 Rev shows up a surprising difference (and likewise with the 140mm 426 maxle Rev, which was basically a lighter Pike)

The worst being the 2006 original revs uturn 426 qr model, flexier than the stw combined bottoms and that's saying something.

:d

"worst being the 2006 original revs uturn 426 qr model, flexier than "
Claimed to be the stiffest 130mm fork at the time iirc.
So more than upto 2006 30mm Fox
Noticable better than my '04 30mm MX Pro's
Also noticably flexier than my (32mm) 2010 20mm Revs

iirc the 2009 140mm Maxle Rev's were only different from 454 Pikes by having the Maxle Lite axle instead of Maxle? hence 50g or so less

What QR skewer are you using?
(internal cam) Shimano could be better than a worn external
A DT RWS claims to make things stiffer?

What hub have you? Any option to swap internals/adapters to 9mm thru-axle? (assuming you're on 5mm QR skewer?)
re: 9mm thru-axle, Superstar for cheapness, American Classic lighter, DT RWS lighter and 'safer'?

What are the spoke tensions like on your front wheel? Evenly tight? Or not?
Handlebars/stem? clamp size?

I doubt it'll be the axle alone.

Frame stiffness? Wheels stiffness, weight, tire weight? Head anglre?

All will affect the front end feel.
