Summer has arrived, the trails are dusty and adventure is calling. At Primera Sports, we can’t recommend gravel bikes enough for the summer season. We have a huge range of gravel framesets and for good reason! Gravel bikes are the true Swiss army knife of the bike world.

Two brands that we love are OPEN Cycles and Niner. Both of these brands offer the best in gravel frameset technology and some of the coolest bikes we have seen. Read on to find out more about OPEN and Niner gravel bikes.

OPEN Gravel Bikes

What we love about OPEN gravel bikes is that they have the ability to change what you think a bike can do. The U.P and U.P.P.E.R are super lightweight gravel framesets with some of the best finishes we’ve seen! The true trick of OPEN gravel bikes is their ability to run both 700c and 650b wheels, so that you can have 3 bikes in one!

Run a standard road wheel on your gravel bike frame for a fast, fun and capable road bike that will be at home on training rides, club runs and even crit races. Or, throw a gravel 700c tyre on for a fast, flickable, gravel bike. Perfect for events and even the odd CX riding.

You can also put a 650b wheel in to boost the compatibility of your bike with a 2.0 mountain bike tyre. This way you can have a bike that can go where most mountain bikes can!

OPEN Carbon Lay-ups

With OPEN gravel framesets, there is so much scope to customise the right bike for you.  The first step is choosing the carbon lay-ups. Choosing a carbon lay-up makes for bikes that can handle and transfer power on a kick of the pedals. Choose between:

  • U.P

The OPEN U.P bike frameset is the entry option with a slightly lower grade carbon. However, the frameset comes in at a crazy light 1430G for frame and fork.

  • U.P.P.E.R

The Open U.P.P.E.R bike frameset comes in at 1250G. The U.P.P.E.R is able to drop its weight with the introduction of higher modular carbon in specific areas on the frame. This keeps the stiffness and ride characteristics the same whilst offering a lighter, nimbler frame. The U.P.P.E.R. accepts flat-mount brakes and ships with an OPEN U-turn fork.

Both OPEN gravel bike frames combine performance-oriented road geometry and parts with clearance for mountain bike tires. Start on asphalt, try gravel, hit single track. Its geometry makes you fast; its tires unstoppable.

OPEN gravel bikes only come in a frame option, so the build is key for making this bike come to life. At Primera Sports, we stock the best components from brands such as ZIPP, Easton, Shimano, Sram, Hope and many more. We have over 25 years of experience in custom bikes and can source components and rare parts for your next OPEN custom gravel bike build.

Niner Gravel Bikes

If you are looking for a complete build, we have you covered with Niner gravel bikes. Niner offers amazing gravel bikes straight out the box. There’s the choice of both aluminium and carbon to fit every budget. Niner is renowned for making very fast mountain bikes and they now design capable and fun gravel bikes too!

With Niner’s heritage in mountain bikes, their gravel bikes are more than capable off-road. We recommend choosing a gravel bike if you want to explore your local area from a different angle and stay safe off the road. Gravel bikes are also great for exploring new areas that your road bike can’t get you to.
