    Thru-axle Rigid Fork

    Is there any advantage to using a thru-axle front hub on a rigid fork for CX use?

    For example on pisgahproductions Waltworks:

    I would think that the necessary weight penalty would far out weigh any possible positive changes. Something a wheel that could make use of a DT RWS 9mm QR would get you a lot of the way in terms of stiffness for very little weight.

    I do love the look of that fork though. Shiny.

    Isn't the point of Thru-axle mainly to counter the torsion due to differential movements in the two legs of a suspension fork ? What's the benefit on a rigid fork ?

    It looks cool and it's different from the norm. What other benefits do you need?

    I agree, but for most of the people racing it wouldn't really matter.

    I also think a through axle on a CX bike would be pretty useless, the weight penalty would negate the benefit and I also feel my current quick release works perfectly fine.
    I only ride bikes to fill the time when I'm not skiing.

    I have a 20mm thru axle fork that weighs 700g and a wheelset that weighs 1600g. The weight penalty isn't there, if you want to spend the dough. I does make a difference in the ride.

    How about some more detail on that homemade rack? Looks interesting.

    I would like to have one for my rigid SS so that I can share the front wheel from my suspended 29er thru axle Minute on occasion. I know I can convert hubs, but that is time consuming since you have to remove the rotor to swap them. I would like to just change front wheels and go.

    Let's see...
    My reason for getting the thru axle: I had just broken my QR WW fork and was looking for something that could take more abuse. The 1st fork broke at the top of one of the legs so I figured that one leg flexed further back than the other. Solution: bolt everything together and put a fat axle down there. There IS a noticeable difference. This fork does not have much (if any) give. It feels the front end on a BMX bike.

    So, to answer the OP, Yes, there are advantages (I'm assuming you mean in XC use not CX...) Mostly, It's ridiculously stiff and I doubt it will ever break and that inspires me to do stupid things on it. Also, I only have 20mm wheels and they all swap between all the bikes in my house.

    Good job!

    Thanks! That is a great fork, if not for shear aesthetics and originality. I do think it would stiffen up the ride ALOT. I have both a taper bladed and straight blade Waltworks fork, and the taper has some good vertical flex, whereas the straight does not, though I'm not one to easily flex anything. When having Walt build I referenced your fork as an option, hey, even saw it for sale, but that was a snafu-or-something. Anyways, it's inspiration none the less.

    I like that.

    If I was having a fork built and either already had a 20mm axle front wheel or was planning to get one built up, I would definately go that route. I think that there would be some benefit gained with those long legs on a rigid 29er fork. I also personally prefer something with a little more bite than the roadie type QRs most people use to save weight and find it hard to believe that the typical 20mm axle setup weighs significantly more than the only QR I have any real faith in.....a steel Shimano QR.

    Now if any of that is true or not.....oh well, it would make me happy.

    In cyclocross you change bikes, not wheels. You change your own wheel and the race has gone by.

    Doubt it makes a performance difference on an already very torsionally stiff steel fork (suspension fork - definitely). The easy change out on a stardard QR - while something I don't do often - is something that probably outweighs the next-to-nothing performance benefit on a rigid steel fork.

    All that aside, the fork in the post is super nice looking and would use it if I had it.



    Is that a SS WW with horizontal drops?
