Hmmm...this new-old 650B idea really peaked my interest since I have been seriously looking into the concept of building or buying a full-suspension 69er (that's a large 29er front wheel and a small 26" rear wheel on the same bike). Why?...I have tried several 29er full-sussy bikes and just never felt at home one. On the other extreme I found I have a preference for 26" full-sussy bikes, but I also found that I dislike the small front wheel (it's much more prone to endo action and I really hate going over the handle bars). So the whole bigger wheel in front and smaller wheel in back on a full-sussy bike made sense to me and I wanted to find out if it would be the ultimate super-butt squish ride for me.
So I was drooling all over Trek's new top Fuel 69er (actually I still am - yes I want one) when Kirk Pacenti alone had a real 650B mtb tire made - that man has some serious faith in the 650B tire size to pony up the $$$ to have one mass produced (yes it takes money to make a tire mold). After many obsessive "research" hours spent looking over the whole 650B thing I decided I was going to build a FS bike of my choosing and drooling that was like the Trek 69er, but built with a 650B tire up front vs. the overly large 29er tire up front.
My Ellsworth Truth is the bike I chose - you may recall that in earlier posts I said the bike was a rough draft...well that rough draft has come much nearer to completion with a Pacenti Neo-Moto 650Bx2.3 tire mounted to a Velocity Blunt 650B front wheel laced to a DT Swiss 240 disc hub (HOT!!!) that I just built up. I also enhanced the rear wheel with a Bontrager Jones ACX tubeless tire mounted onto Stans Notubes ZTR 355 rim laced to a DT Swiss 240 disc hub. More enhancements are still planned so I have the say the bike is still in draft form.
The ride with the 650B front wheel is better than I had hoped...more testing (time trials, long hauls, and pure sufferage) as weather permits, but so far all I can do wonder in awe...Is this a bike I will actually keep longer than a few months? Any bets?
