Thanks to Jason for sending the link to this: Found at Frostbike by Halter’s Cycles, the Problem Solvers E46 BB Adapter lets you run a singlespeed drivetrain using a standard crankset inside a BB30 PressFit30 (PF30) shell. The eccentric design tightens up chain slack, so you can basically take any BB30 frame with standard vertical dropouts and convert to singlespeed.
As more and more frame builders move to this standard (and we think they should given the availability of adapters to then run anything you want), your options should continue to grow. The E46 Adapter will be available in June 2011 for $150. Oh, and we’re pretty sure the folks at Problem Solvers are at least a little crazy. Check out the wooden rollers they brought to the show for proof, right after the break…
UPDATE: As the folks from Team Beer pointed out in the comments, this is for PRESS FIT 30 BB shells only, which was just clarified by Problem Solvers today in a press release, posted after the break:
PRESS RELEASE: Due to the ever-changing industry standards and lack of standardized language, there’s been some confusion as to what our E46 bottom bracket does, and what it works with. The release should explain it’s intended use, but here’s a few key points:
- The E46 fits shells that are 46mm in diameter. This is the same diameter as accommodates SRAM PressFit BBs
- This IS NOT compatible with BB30 bottom bracket shells. Those shells are 42mm in diameter.
- The E46 accepts 24mm spindle cranks commonly used in external bottom brackets
- This combination allows for 16mm of fore/aft adjustment to add/remove tension from the chain
Actually, the rollers were in Surly’s booth, but PS’s Sean was crazy enough to try them. They also had this freebie for stopping by the booth:
