Back in Stock and New: Framebuilding Parts

Good news: The long-awaited Kaisei ‘TOEI Special’ fork blades are back in stock. Even better news: We worked with Kaisei to maximize their length, so there is a little extra for bikes with ultra-wide tires, or to cut off the bottom part that is hard to bend smoothly. The new blades are 430 mm long instead of 405 mm in the past.

Why do we love these fork blades? The fork is an integral part of the bike’s suspension: It absorbs hits that are too big for the tires to handle alone. The difference in comfort is really remarkable when you ride two bikes with the same tires, but different fork blades, back to back. As since the improved shock absorption reduces the suspension losses, a fork with a little give also makes you faster on all surfaces.

The ‘TOEI Special’ fork blades work perfectly with our ultra-strong and ultra-light Rene Herse fork crown.

We’ve added a third chainstay to our Kaisei tubing program: In addition to stays with 0.7 and 0.8 mm wall thicknesses, we now offer 1.0 mm stays. These are ideal for bikes that carry a heavy load, and for riders who prefer a stiffer feel to the drivetrain. We offer them both straight and custom-bend to clear wide tires (above).

 

The Rene Herse bottom bracket shells are designed to fit the curved stays, with a socket angle that is a bit wider than standard. Available both for standard and OS down tubes.

Another addition to our framebuilding program: Hahn Rossman has redesigned our taillight mount. It’s now much easier to braze, and your builder can shorten it if you prefer the taillight to be closer to the seat tube. (The new braze-on does require a larger hole in the seat tube, but we’ve found that this doesn’t cause any problems.)

We’ve sourced and designed our framebuilding program for bikes that traverse entire mountain ranges in one go – because your bike should not limit the adventures that you can imagine.

    Do you think it would be possible to use Kaisei blades with disc brakes when SRAM “predictive steering” hub is spec’d? That hub with the special axle design is said to prevent torsion even more than thru axles.

    I know you prefer rim brakes, but for some applications discs have merits also, e.g. commuting in my case where they work really well on with super low maintenance.

      I think these blades can be used with discs, if the fork is designed for it. I’d use straight blades – no need for a curve when you put a bit disc tab down there anyhow. All you do is concentrate all the stresses at the end of the bend… We’re working on some designs right now.
