The bigger thing going on is that your front wheel will be kicked out just a wee bit more, making the wheelbase just a bit longer and that 'might' get rid of some of your "scrub" problem. Dave:

I'm in and in to stay. I appreciate the advice about doing your research on the rigid fork to frame combinations. In fact, that's what brought me here. I'm anxious, though, and I was hoping you'd care to comment on my fork consideration. Riding Kona Kula 2-9 with a Karate Monkey fork. I very much like the way the bike handles. I've heard it can get even better though with a better fork. One possible complaint might be that the set-up tends to "scrub-out" a bit easy when cornering too sharply. Likely just pilot error but I'm considering the On-One Carbon fork due to the 47mm rake, among other things. Have also looked at Willie and Willits forks. Kula 2-9 with On-One carbon - what do you think? Guitar Ted – thanks for bringing me up to speed on all things 29er. I’m in and in to stay.

I'M NOT SIGNING UP ON RIDEMONKEY TOO DAMMIT!! bad enough my speedcity 29ers are glaring at me for finding out that notubes makes ztr's in 650B sizes (a mere week after I bought the mavs) :P screw it, ride the 29er hooligan rigid till something goes wrong, or at least until I'm done modifying the 'zocchi... oh fer crying out loud….

Yes, I do recall now that somebody was doing this very thing with Girvin and Amp Research forks back about 5-7 years ago now. In fact, the uber-rare Look Fournales fork is currently being sold over at Ridemonkey in the 29"er forum. Probably the best 29"er linkage fork by a mile. byknuts: Sounds very familiar.

I've got a soul cycles hooligan, older model with horizontal dropouts, and it JUUUST fits a 29re in back, with tons of clearance on a suspension corrected rigid fork meant for 26'ers, until I decide I'm in for life it's my test rig. (none of this is important for my question, just setting the tone for my level of experience here) I was wondering if anyone had simply gotten new legs made for a girvin fork or a lawwill fork that would fit a 29'er wheel? Figure a columbus downtube or something if welded up with dropouts (increased offset d-outs natch) and a disc mount would do the job as a girvin leg. Seems infinitely simpler to make, especially considering girvins aren't expensive these days... I figure if someone took the linkage idea and ran with it they could make eccentric link axles to adjust the legs angle to a preferred offset. I built my friend a cyclocross bike with a 700x38 wheel in a girvin fork, and found it to still have good clearance under the crown under full compression. Girvin crowns by the way and REALLY short and contoured to the tire's profile, so the whole wheel stays closer to the bottom of the headtube as opposed to a regular suspension fork.

While I hate to hear of this news, the fork will be usefull in this experiment as it has 44mm of offset, which puts it squarely inbetween the forks I have of similar axle to crown height. :) Wish I Were Riding: Actually, Twenty Nine Inchs reviewed the Wilits WOW Fork last year.
