I am looking to replace my old RS Tora forks with some rigid forks. Had a look on the On One site and they have both steel and carbon forks that look good but with a £60 price difference.
I am not bothered about the weight, both sets of forks are much lighter than the ones they will be replacing but was wondering about ride quality, do the carbon forks really make a big difference?
The bike they are going onto is a Charge Duster which is mainly used for road commuting, occasional Glentress rides and rides over the Pentlands (natural terrain).
There’s a hell of a difference. A good steel fork is comfortable in the kind of way that you remember it years later with fondness but a carbon fork paired with a fattish tyre is almost as good as short travel suspension forks; comfortable on most terrain and you only notice it’s rigid on big hits like steps and brick-sized rocks.
I carried and rode my titanium Global with a carbon fork for 25 miles and 5500 feet over and round High Street with three guys on full suspension bikes. None of them was able to pass me on the downhills and at the end of the day I still had fuel in the tank thanks to the lighter weight of my bike. And I’m 55.
I got my carbon fork from here and very good it is too: http://www.carboncycles.cc/ I like it so much that I’m selling my Rebas, which weigh a ton and leaked oil from new until I got the importer to rebuild them.
If you’re in Lancashire you’re welcome to test ride my bike.
Do you not have carbon forks on a roadie? I notice a huge difference when riding my CX compared to my dad’s hybrid (carbon on mine). You can see the forks moving backwards and forwards when on the rough stuff, and it definitely takes a bit of the edge off.
I have carbon forks on my road bike, they feel pretty stiff. The carbon forks on my last road bike were quite flexy I guess, since they were quite comfy.
The on-one carbon forks are actually very good, and surprisibgly strong. Mine have been battered and jumped for 4 years with no probs, just got a second set on another bike. Definitely aid comfort.
The on-one steel forks are stiffer and heavier. Spend the £60 now or on wrist suppports later – your choice.
What Globalti says, pretty much.
I’ve got Salsa CroMoto and Nukeproof carbon forks (exactly the same as On One I would imagine). Used them both on the same bike this summer, whilst riding regularly in the Yorkshire Dales. Predominantly, this sort of non technical terrain
Hand on heart, the carbon forks made for all round enjoyable days out, especially when I was unfit at the start of the summer. The trade off is it makes you a bit restraint on the technical rougher descents, picking lines etc, but the climbs are much easier, having a lighter bike and no bob, it makes an overall really enjoyable ride out. I’ve had no fatigue in my hands or wrists after 4 hour rides (I used to suffer quite badly in the old days and I was 20 years younger). The amount of flex you can see in the forks when you’re descending/braking is quite unnerving.
The Salsa CroMoto forks were only used for a few rides to compare, as said above, it was just like going back to my first mountain bike 20 years ago before suspension forks. I don’t think the Salsa forks are much like the On One steel forks, so maybe different flex.
I would probably never ride in the Lake District on a fully rigid bike, I go there to get a bit of an adrenaline rush and to ride technical terrain, rigid forks would spoil it for me.

I have both On-Ones & the the Exotic carbon ones, like those from Carboncycles above. The Exotics are much better finished than the One-Ones.
I can vouch for the strength of On-Ones though, after hanging in the air for seemingly ages in an endo after the wheel dropped into a ditch.
Grab a nice big front tyre, 2.5 WTB Weirwolf if you can get one; & its like a suspension fork.
Also, depending on what travel your running on your Toras, you might want to consider a 29er fork (470mm). My Inbred was loads better with a 470mm fork than a 440mm (100mm travel 26″ fork). It felt too low at the front after running a 130mm travel suspension fork.
Got to agree with Cynic-Al, in the lack of decent (light!!!) steel forks, especially when there are nice steel 29er forks like the ones Niner & Singular do.
daveb – what about secondhand? Could sell you some s/h carbon (superstar) forks that I used fairly infrequently on my ss. Uncut steerer, no marks or cracks etc. They’ve been sat in the garage for ages!
Drop me a mail at rtedgeAThotmail.com if interested.
Before anyone says not to buy s/h carbon, I do work in composites for a living 😉
On the subject of running rigid carbon with a big front tyre (2.4 instead of 2.1) – what does the big front do for the drag? Or do rear tyres make the most difference?
Just as an alternative view I’ve got cx bikes with steel forks, Easton carbon and on my main race bike they’re the integrated Argon 18 fork. The steel fork on my 95 islabike is very compliant, the easton fork on my bmc is incredibly flexible – to the point of being almost unrideable at times, and the fork on my Argon 18 is the stiffest thing I have ever ridden.
It all depends really upon how its designed.
With carbon you not only have the shape to play with to change stiffness but you can change the orientation of the fibres to give you properties you want.
eg a carbon driveshaft will be dominated by +/- 45deg for torsional stiffness but a beam designed for simple bending will be dominated by 0 deg fibres along it’s length.
I remember seeing a broken front wing of an F1 car when doing some work for Benetton (few years back) and two men could jump up and down on the ends without breaking it but it had been snapped while moving it and banging it at the wrong angle against a bench.
A good demo is 2 identical looking pieces of carbon fibre about 1″ wide by 10″ long – one with mainly +/-45 and the other with mainly 0deg. Both same thickness.
Get the person to try bending and twisting tests on each and they soon realise how much you can influence the properties.
I have been riding my carbon Exotic forks in Derbyshire on some of the rocky trails up there and I have been amazed at how comfy they are! After a few hours riding over all those rocks I was expecting sore wrists, but no they were fine. In fact I have rode those rides on Full suss and front suspension forks on a hardtail and I really did not miss them. Good forks the Exotic ones. Plus they don’t have those horrid yellow Nuke Proof logos in them.
daveb am interested in how you get on with them.also have a duster,and would like to get some rigid forks for it.was thinking of carbon,but the price has made me think of steel instead (admittedly was looking at dt swiss 😉
i have a carbon exotic fork on my Cotic Soul, I was pleasantly surprised by how if soaked up rough surfaces & gave a very compliant ride, I love it! At the price, it has to be recommended!
No point you can get new Exotic carbons for about 30 quid more on ebay than the On One steel forks. The On One steel forks are rubbish too, heavy, look crap and not forgiving at all!
Or aluminium forks….
I’ve used these Mosso mtb forks bought off ebay on a few bikes, well made, cheap, really light. Used to be about £30 delivered but seem to have gone up a bit now. Never had a problem with deliveries or busting them yet.
I think they do carbon versions too for about £20 more.
