1. If you’re not living a cave or stationed out in the middle of the ocean on Diego Garcia doing god knows what, you’ve probably seen 44rn_design’s track chainring on your RSS horizon.  Aaron spent 2 years designing, prototyping, testing, spec’ing and sourcing the final US-made track chainring.  I found a few free minutes today to drop my new purchase on my bike, along with an Izumi V chain and EAI Superstar cog for full-on drivetrain refreshness.  I’ve never felt a smoother set-up- there’s an absolute positiveness to the ring that offers and incomparable ride experience.  Aaron’s careful engineering and honed design results in zero slop between the teeth and the chain bushings and the overall effect is a ninja-quite drivetrain that delivers 100% of rider energy to your wheel.  Only 50 of these rings were produced: 20 silver and 30 black, 144mm BCD and 47T only, and they’re moving quick.  Buy your MA-designed and -manufactured ring for a measly $67 here, while you still can.  Full details on the design and process here.  Pictureset of the rings mounted up on various track cranks here.

  7. Here’s what became of those Henry James track ends- shaped them reminiscent of the old Campy “football” ends, but thinned out.  Curved chainstays for a comfy ride… Thanks for the hook-up, Ian!

  8. Why I love Somerville- short a set of Pacenti track ends that never came, I only had to walk a block to Icarus, where Ian hooked up a set of Henry James.  Jamie’s graduation present is back on track.
