Gravel Grinder News: Ergon GP1 Evo, Bookman Volume Light

Gravel Grinder News: Ergon GP1 Evo, Bookman Volume Light – by Guitar Ted

Today we have a couple of new products, the Ergon GP1 Evo and the Bookman Volume Light, that we will be doing Quick Reviews on soon. This post will serve as a brief introduction to both products. As always, I (Guitar Ted) was sent these products at no charge from Ergon and Bookman for test and review. I am posting my thoughts here on Riding Gravel without any compensation or bribes from anyone. I will always strive to give my honest thoughts and views throughout.

Ergon GP1 Evo: The redesign of the flagship grip from Ergon, the GP1, is now out. Dubbed the GP1 Evo, as the name might suggest, this is an evolution of that iconic winged grip.

Using a manufacturing process that reduces waste to near-zero, and using refined rubber and natural cork (GP-1 BioKork Evo) , this grip represents a responsibly produced product that is 100% manufactured in Germany and is SGS certified. Using SGS certified, pollutant-free, medical grade rubber, the grip meets German toy and food standards. 

In the case of the BioKork GP-1 Evo, the grip contains 40% organically grown cork from Portugal and the rest is manufactured to SGS standards in Germany. 

The aluminum clamp is integrated into the GP-1 Evo and BioKork Evo grips and now features a hidden hex head clamping bolt. 

Prices are $39.95 for the GP-1 Evo and $49.95 for the BioKork GP-1 Evo. These are available now via Ergon’s Amazon partners or from bike shops with a Quality Bicycle Products account. 

I have the size Large GP1 Evo already mounted and will be back soon with my thoughts on how this redesign of the GP1 is for riding single track and gravel. Stay tuned for that.

Bookman Visibility “Volume” Light: This is a product which won a design innovation award at this past Summer’s Eurobike show. The Volume light is a unique take on the self-contained LED bicycle torch and can be had in two power levels – A 1500 Lumen maximum power or 800 Lumen maximum power range.

Unique to the Volume is its namesake “volume knob” on its right side which serves as a power level selector. The knob can be rotated quickly to any one of five power levels on tap. A quick hit on the power button, located on the top/front of the volume, and the light switches to flashing mode, which also has five power levels, and those are selected by the knob as well.

Furthermore, the Volume utilizes the ubiquitous Garmin style mount. No more proprietary mounts! The Volume even comes with a spare mount that also has the Garmin style attachment to the light, but is compatible with GoPro mounts. That’s smart.

The Volume in the 800 Lumen power level can be had in three colors, White (tested), Orange, or Black. Price is $107.00 USD for the model I have on test. I’ll have some light beam shots, more specs, and a ride performance update in my Quick Review for this site coming soon.
