    Not all rigid forks are built alike

    ... But then, you lot already knew that. Prior to X'mas, I was riding around with some old Jamis steel fork (came with the frame I bought off ebay). Everytime I rode over even the narrowest root or a smallest crack on the road, I'd literally feel the shock in my teeth. This was the price of riding a rigid fork, I figured.

    Couldn't be more wrong. Wifey got me a Kona Project 2 fork for X'mas (recommended by you lot, and I dropped plenty of hints prior to X'mas!). I covered about 50 miles with this fork last week, and the ride was like night and day. The jarring shocks were gone. The aches in my arms were gone. The harsh ride was gone. I seemed to flow nicely over trail bits and bobs now. The feel wasn't muted, per se, merely softened, if that makes any sense.

    All this from a fork that no suspension?! Don't get me wrong, I'm not talking some mythical plush ride here - a rigid fork is still a rigid fork. But I was more than amazed at how much more comfortable this fork was compared to the one I was using to get by.

    In the end, I just wanted to thank you lot for helping me get a better fork. I'd post pics, but then you lot already know what a P2 fork looks like.

    Interesting. I have wondered more specifically what makes one rigid fork better than the next. Materials? Design? Luck? Price?

    Something I have been considering trying, but I would love to hear more on why this is so.

    I recently got a Kona Project 2 fork too. Have only ridden it around the block a few times, so I don't have any opinions yet, but glad to hear you like yours. I like the looks of the straight blades, reminds me a little of a BMX fork.

    Some things that might make the P2 ride a little better is that they are fairly light (claimed weight of just under 2 pounds) and the fork legs are triple butted.

    even worse/even better

    no actually all rigid forks are exactly the same, all made by Spinner in Taiwan, they just change the decals and paint.

    only kidding

    If you dislike the harshness of the Jamis fork, try a Tange Switchblade, it makes the Jamis or any other seem plush.

    And if you love the Kona, great fork, try a Ritchey Logic with raked blades. The Kona will feel harsh by comparison.

    Discounting materials and assuming we're comparing chrome-moly steel rigid forks of identical offset, the differences are the result of blade diameter, wall thickness, and whether and if so how and where the tubes are butted. Lots of room for variation within those contraints.
    Ideally a fork blade would flex evenly from the crown down to the dropouts, in order to get the most flex from the length of pipe. Since the highest leverage on the blades is at the crown, the upper section of the blades should either be fatter or thicker, or both. At the dropouts, leverage is least so the blades should be smaller diameter (as are most all raked forks) and/or thinner wall. Most straight unraked blades of consistent outside diameter have thicker walls up high, thinner walls down by the dropouts.
    Yeti AccuTrax is another sweet riding rigid fork not unlike the Kona. Both are versions of the venerable Koski Type 2, which is itself a knockoff of BMX forks.

    Not being as smart as some of you, does the P2 come with brake mounts? On their site it doesn't show any, except on the disk fork, but I don't have disks. Also, and good places to get these?

    Older P2 models you may come across on ebay have both v-brake and disc mounts. I believe the newer ones only offer one or the other. I shopped around hard for mine and the best deal I could find was from The Bike Company. $50 for the fork, plus another $10 to ship. I found the ebay gets a little nuts when buyers quickly turn into morons and start bidding upwards of MSRP.

    Is the P2 now a straight-blade fork? Kinda looks that way from the pic

    I rode one for several years,I don't think they are making them anymore.

    You know, I've only done two rides on my rigid forks, but I have to say, I attribute the smooth ride to me running a Tioga Yellow Kirin Pro 2.3 on the front at a reasonable pressure, the fork design runs a very distant second.

    Think about the physics - how much difference in deflection can there possibly be between rigid forks of any brand? Not a lot. We're talking a few millimeters here, whereas how much does a 2.3" tire compress when you hit a bump? Heaps more.

    The design of the fork can make a difference, for sure. My fork is suspension corrected, double butted, and features a very old school 50mm of rake. That's how you make a proper rigid fork IMHO.

    Makes for a pretty floaty ride over small undulations, fersure.....but it sure ain't no Fox F80.

    I agree, theres a seller on Ebay thats been offing the P2 forks NIB. Most end up going in the 55-60$ range. I jumped in on one that ended late on a Friday night, lucked out and got a Vbrake P2 for $41plus shipping. Theres a lesson for us all, have your auctions end during business hours

    The Bike Company has P2's (disc or v) for $50. I got mine from them a while ago...

    For me, rigid forks (P2 included) don't provide enough (any?) flex to keep my elbows happy. Even w/ a fat 2.4" Mutanoraptor up front. I can only run a rigid fork occasionally or my chronic tendonitis acts up.

    It definitely ain't all tire...

    After having spent the last 2 years on a Merlin with a Vicious rigid fork and then going to a KM with that rigid-as-hell fork and now a custom Rock Lobster with rigid fork....I can definitely tell you that your fork has more to do with it than you think.

    Case in point:
    I rode the KM with the stock for for about 8 months, and was happy with the bike, but did not feel comfortable "letting loose" on rocky/sketchy downhill sections. I then happened on a Sycip custom rigid to slap on it. Night and day difference. Same tires, same wheels, new bike. So much more predictable. No longer randomly throws me into things when I hit rocks at speed. Enter custom Rock Lobster (pics can be seen in 29"er forum). Improvement again. Different wheels, but same tires (WTB nano 29's). Both the Sycip and the RL forks track very well in turns, yet are predictably compliant to bumps, especially the small stuff.

    I rode a suspension fork for a few years, but I am just one of those people that have never gotten used to them. I prefer the predictable tracking of a good rigid fork, and I cannot stand the dive in suspension forks when rolling off of 12-18" rocks/ledges. Simply a personal preference. But I will say this: those of you that enjoy the Kona P2 forks should at least take a ride on a custom steel fork, like a Vicious/Sycip/RockLobster/etc/etc. The ride quality goes up again.

    All the same rake and length?

    I'm sure GEOMETRY can have a big effect on bump response too.

    The P2 has always been a straight blade fork.

    They are facing forward so that when the brakes are applied the force won't 'rip' the wheel out of the dropout - it is actually a good idea.
