The Freedom To Explore

GRiT Frameset

The ultra-capable go anywhere gravel and adventure bike

Frame & forks from £2500.00 // Complete bikes from £4455

The brief: To design a technically exceptional and beautifully crafted gravel frame for epic go anywhere, ride anything adventures.
A geometry that breeds confidence on testing terrain and encourages you to explore more.
The result: A refined, unflinchingly capable and stable all terrain gravel bike for explorers that can be tailored to suit adventures great or small. A frame that provides confidence inspiring handling and aesthetic beatuty in equal measure.

About the GRiT
Buying a J.Laverack is more than buying a bike. Each bike is commissioned to your requirements and we employ a no compromise mantra to offer the best advice.

TTHE GRiT has been a long time in development,” said designer Oliver Laverack. “We have been determined throughout the design and testing process that this should be a no compromise, aesthetically beautiful gravel adventure bike that will inspire confidence no matter how gnarly the terrain. We also wanted to set our new gravel bike clearly apart from our extremely capable J.ACK, which has abundant off-road capability, but is more road and rough road focussed.”

GRAVEL ADVENTURE GEOMETRY & COCKPIT
Up front, the GRiT fork offers ample tyre and mud clearance and features a longer rake, increasing the gap between your shoes and the front tyre, which is important on slower technical terrain. Longer chainstays, combined with a meticulous bike fit, place the riders weight further back for increased traction over loose terrain. Both the longer fork rake and longer chainstays also increase the stability of the bike over rough sections at speed.

All models feature wider flared handlebars and shorter stems to take the riders weight off the front of the bike and keep handling responsive and light.
This bike can be configured in so many different ways, depending on the type and size of the adventure. Build it up with a full complement of frame luggage and tackle a trans-continental adventure, or simply run two bottles and head out on your local trails, you decide. The GRiT will take any adventure in its stride, be it big or small.
“The ride characteristics of the GRiT have surpassed even our own expectations and combined with super wide tyre clearances, that will allow for up to 50mm 650B tyres and 48mm 700C tyres, this bike is an unstoppable adventure machine,” said Oliver.
“In our eyes, titanium is the best material in the world for a gravel adventure bike; it’s the ultimate metal with mettle. The rough and tumble nature of gravel and off-road riding means riders will push their limits and need a material that will stand up to repeatedly being ridden hard”.

Design Features
Unsightly dynamo cables are no more with our internally routed dynamo cable option.

Reliability and simplicity and are king where bottom brackets are concerned and for this reason we recommend threaded bottom bracket shells.

Gear and brake cables are routed internally to protect them from the elements and ensuring smooth shifting and braking.

A wider head tube where the fork meets the frame increases the stiffness in that area, reducing flex and improving steering precision.

Beautifully integrated Streamline head tube and / or bottom bracket that allow all cables to be hidden and protected inside the frame.

Custom geometry to ensure a bike that has been made to your measurements to the millimeter.

Run up to 50mm tyres with 650b wheels or 48mm tyres with 700C wheels.

Add even more versatility by opting for mudguard and rack mounts and open the door to winter riding in comfort or multi-day rides with a pannier for the overnight stay.
