James Frames, Custom 650B

OK, my JP Boylan built frame is a complete bike, and refined! I had it built up in mid March, but it needed a few changes- which have occurred. The original build consisted of a too lengthy of a stem, and too high of handlebars. I've brought the steering lower and changed the fork from the X-Fusion Velvet to the Maverick SC32. This mandated a new front wheel, too. Luckily I had a matching rim laced to a Maverick 24/7 hub. The IRD Fire XCPro B* model Tires are very good, but I am waiting to mate my Pacenti 2.3" NeoMoto to the upcoming 2.1" Neo Moto on the rear.
I haven't taken this version off road yet, but pedaling in the neighborhood has me stoked for the trail.
Here is the final (hopefully) version of the James Frames 650B custom aluminum build. Unless, for some odd reason I choose to add gears...

JP is a great builder, who at one time worked for Dean Titanium, and I've heard he helped Walt of Waltworks get started. Check him out at www.jamesframes.com

(* I will be posting a write up on the IRD Firx 650B tire very soon)

Let us know how that Fire XC/Pacenti Neo? combo works out on the trail.

What's the weight on that bike? 23 pounds? Or less than that even?

It is a great looking frame. Want to post specs somewhere? I was curious about the seatpost and saddle and want to know when flipping the fork started happening for mountain bikes.

Umarth: "want to know when flipping the fork started happening for mountain bikes. "

This has been going on for YEARS.
Companies like Bombshell Parts, Marzocchi offers the Shiver, Manitou has the Dorado, Atomlab has uni-crown inverted suspension fork, even. White Bros has been building them in the USA. Needless to say, this is not a new idea.
With Maverick's forks, thye have made the 26 and 29" compatible with a Maverick travel reducing spacer. With a modified spacer, the fork can be a dedicated 650B suspension fork.

Do you know if the inverted fork idea was stolen from motorcycles or vice versa? I'm fairly new to mountain biking and I've only ridden a rigid bike, so I don't pay much attention to suspension. I really like your build....
