Gravel Grinder Gear: Singular Cycles Gryphon Frame/Fork

Singular Cycles in conjunction with their U.S. distributor, The Prairie Peddler, has provided a Gryphon frame and fork for test and review on Twenty Nine Inches. Since this is a drop bar specific, rigid only design, it would also be a great gravel grinder rig for many riders.

Due to that fact, I will be writing about this Singular model here as the testing progresses on Twenty Nine Inches.

Now, for some brief details and why it is my opinion that this bike should be here.

The frame is double butted steel with a Reynolds steel fork that is designed to be used with an off road type drop bar. It can accept tires up to 2.3" in 29"er size, or be run with tires as skinny as 40mm with tons of mud clearance. The frame is fitted with an eccentric bottom bracket and the insert which is provided, is a Phil Wood unit. This would allow you to set up the bike as a single speed/fixed gear, or there are cable guides and a rear derailluer hangar for geared set ups.

The versatility of this design makes for a great choice for gravel and back roads. Single speed and fat tires for winter training, then set it up with gears for your summer events with 42mm fast tires.

The frame is disc only, 135mm spaced in the rear, has forward facing drops on the fork, two water bottle mounts, a 27.2mm seat post diameter, and comes with the Phil Wood BB insert and a seat collar. Stay tuned for further updates.

Note: This frame and fork were provided at no cost for evaluation and review. Twenty Nine Inches, The Gravel Grinder News, or myself are not being paid, or coerced to write a favorable review. An honest and accurate opinion will be given to the best of my ability.
