    a Fatty for 29er ?

    Fatty has 80mm travel


    as a Lefty reduced to 29er

    can be the Fatty used on a 29 er ?

    not, because wheel touches the upper or arch of fork ?

    or yes ?

    A 650b does not clear a fatty so a 29er is out of the picture. The tire hits the crown where the air valve is.

    Fatty on cx1 can surely clear any 29" tire. Problem is with the rear wheel - in a week or two I'll know if 650b with 2.2 tire would do the trick (monster cross).

    Technically, 'No.' However, in an attempt to avoid buying a CX1 or Bad Boy for dedicated road/bike trail use, I managed to fit a 29er wheelset on my 2000 F2000SL with the Fatty Ultra Headshok and Continental 700x35 Cyclocross tires. Tire pressure as shown in photo is approximately 50psi.

    Wow That looks great with the 700C/29r combo wheels. How does it ride ? I wonder if my 29r wheels off of my 2010 trail sl4 would fit on my 2000 f500. I have the original SB 8tires.

    Problem is, if they made a 29er Headshok (with enough clearance for normal, popular sized 29er mountain bike tires), the fork legs would be longer, add the suspension distance between the fork and the frame, then add the headtube length and headset cups if not integrated... The front end would be waaaaaaay too tall, a skyscraper! It's already a problem with 26" Fatties and it's already a problem with 29ers, both can be solved in most case with an appropriate stem, but combine both, you'd need a -75° stem to have the bars at a usable height... Plus, a 29er Lefty has the same travel, is as stiff, uses a stiffer front hub but is lighter than a Fatty. The only thing the Fatty has is better looks IMO. Very nice bike valiant1974!

    Unfortunately, I haven't ridden it more than up and down the street in front of my house yet. I just started this project and I'm still adjusting the drivetrain to my satisfaction.

    I would imagine your 29er wheels would work with the F500 too provided you fit them with low profile cyclocross tires with less than 60 psi. At 80 psi, my tires rubbed the bottom of the Schrader valve on the Fatty.

    I doubt the Kenda SB8 tires would fit. I suspect nearly all 29er tires would have too much volume to work with this setup.

    Thanks for the compliment! I'm the original owner. Purchased the bike new from Universal Cycles in Studio City, CA in the spring of 2000.

    Valient1974 Thanks I think you are correct about the SB"s. I do think your bike reminds me of the new CX1. I would think your bike would still handle well with the big wheels and lower cx tires.

    I agree. With the 29er wheelset and 700x35 cyclocross tires, the bike looks a lot like the CX1. And so far I'm only out approximately $50.00 for the new tires and tubes. (The Giant 29er wheelset was a hand-me-down from my brother).

    Cant beat that and your bike is still a made in USA Cannondale and did you see the price on those CX1's ? If you can even get one. I think I may take your idea and try it on my F500. Keep me updated on the ride quality. I wish my Headshock had a lockuot, like the CX1.
