Comments on: OS Bikes Blackbuck: Update http://twentynineinches.com/2008/01/13/os-bikes-blackbuck-update/ 29er Bike Reviews, Rumors and News Mon, 08 Sep 2008 11:49:20 +0000 http://wordpress.org/?v=2.5.1 By: Slate http://twentynineinches.com/2008/01/13/os-bikes-blackbuck-update/#comment-34051 Slate Fri, 01 Feb 2008 00:25:45 +0000 http://twentynineinches.com/2008/01/13/os-bikes-blackbuck-update/#comment-34051 Thanks for the interest guys. I'm looking at a smaller frame but not sure yet if it will be "Blackbuck" style as only one additional inch standover can be had. Headtube length gets pushed down to 3" and there's a lot of leverage. Obviously a rigid fork helps standover. I did a CAD measurement and got 74 degrees. It sounds too steep. But with an even shorter fork (QBP 26" susp. adj.) I rode a local (Very narrow) trail plenty and liked it. Try it, you may like it. I have the rigid fork I'm selling on my bike and it is staying there. BB height gets a bit low (aforementioned very narrow trail) so I'm considering a half link to ideally place the BB. I am very confident that this eccentric BB will not creak for two reasons - the split is not on center and the shell is bored after welding. Also the fit of the eccentric O.D. to the shell I.D. is pretty close. Seatstays (in theory) provide flex for comfort but I cannot really feel it riding. No offense taken if you don't like the look. There is a form follows function idea here unlike a car body. I wanted the caliper on the heavier shorter tube also. And getting a strong seat stay top tube junction was another objective. Just a word on "ETT" (effective top tube)... this dimension varies depending on whether seat tube and head tube are parallel or not. That matters for handling but not necessarily for stem choice. I would also like to note that when Fox asked for tire clearance dimensions from WTB my response included the pitch for a 51mm offset to reduce trail. The steeper front end reduces trail somewhat, but not much. Having ridden 29" tire bikes with fork angles as slack as 70 degrees and as steep as 75 degrees I can honestly say that (for whatever reason) the fork angle seems not to matter nearly as much on a 29er as on a little wheel bike. I would not be offering the rigid fork at the length I have specced without testing. Maybe some will not like it, but it is staying on my personal bike. I truly like negative comments so bring em on. It is difficult to improve when the idea is that the product is perfect as it is. My sincere thanks to G.T. for posting here. I have a site that needs way more attention than I am giving it. I am not necessarily in the bike business. I am more doing it out Of Spirit of enjoyment and learning. Very wet here today in Marin... back to "work". Thanks for the interest guys.

We will certainly post an update if it happens. seckel: Mark is in the works with a smaller frame size, but honestly, unless he sells through the current inventory it may not happen.

To each his own. I believe a certain someone will be the recipient of a frame and fork so we may be able to hear more about how it rides with this so-called shorter fork. It's all good!

Sure, it will still be a bike, but does it make any sence over the suspension fork setup?" No, but when has anything that's been done make sense ;-) ? Mark S has spent time riding such a set up and claims it is no problem - see post #6 above. “73º AND 51mm??

I'll do some further testing and ..uh I mean, I'll be frank, my testing takes a couple years... so I'll need to have it for a bit. I mean, if that's ok and all.... you know.
