The Greylock+ is a road race bike, and a turbo all-road bike, all in one.
  • General Handling Feel:​ Fast & Agile.
  • Ideal For: Fast road riding & racing. Hitting light all-road terrain with speed.
Every Greylock+ is both road race, and all-road capable. It has the geometry of a classic road race bike for all out speed, agility and fast handling. Thanks to some crafty design work, the Greylock+ can fit a wide range of tire and wheel sizes, allowing it to be far more than just a road race specialist. When setup with skinny 700c x 23-25mm tires, its ready for road racing, and can hang with the best. With clearance for up to a 700c x 32mm tire, the same bike can hit light dirt and gravel with incredible speed. Better yet, it can also fit 650b x 38-42mm wheels without mucking up its handling, and upping its dirt road capability. The best way to get the most fun and versatility out of a Greylock+ is to own two sets of wheels: 700c for pavement, and 650b for all-road mode! 
Road Mode:
​Setup with 700c x 25 wheels and tires on a fast, 50 mile all paved ride.
All-Road Mode:
The same Greylock+ as above, shown setup with 650b x 42 wheels and tires. This was out on a 100 mile adventure ride with dirt roads, snow & mud.
