Ride Description:

West to Grafton & the Mystery of the A Screw is a 48 mile road ride on paved roads, with 2,620' of climbing (54' per mile).  During the ride all are invited to help solve a puzzling cycling mystery - all rear derailleurs have a B screw, but why no A screw?

- Did it exist on early derailleurs, but was discarded as they evolved?

- If it never existed, then what does the "B" mean in "B screw"?

- Is Archimedes of Syracuse, who invented the screw-based water pump, involved?

Two leader-led speed groups are available: 12-14 mph and 14-16 mph.  Riders are welcome to "show and go" as well.

At route mile 35 all are invited to stop at "Eli's Lemonade Stand" - hosted by former CRW President Eli Post and his son Alex.

After the rides we'll collaborate on an answer to this longstanding mystery, fueled by  Jack's Abby craft lagers & comfort food.
