Bitmap Pro

A hardcore hardtail with Rockshox Pike forks, Guide 4-pot brakes and SRAM GX Eagle 1x12 groupset.

If you're buying a bike like the Bitmap then you know you're after something that's fast and a lot of fun to ride. The 6061 alloy frame is strong, light and direct, with low standover height, a slack head angle and aggressive geometry. There's no point messing around with the build kit; you need plush forks that can handle some abuse, strong wheels and brakes that work.

The Bitmap is built for a 1x drivetrain and we reckon GX Eagle 1x12 is the best bang-for-buck groupset out there. So it goes on the Bitmap Pro. Smooth, precise and consistent shifting, great reliability and a massive gear range. We spec a Descendant crankset which matches up with the Descendant 35x40mm stem and 800mm bar which is perfect for a hard-hitting bike like this. Stopping power is provided by Guide R 4-pot hydraulic discs on 180mm centreline rotors front and rear. There's a Reverb Stealth dropper (150mm or 170mm) which of course has the 1x remote lever. 

Up front the Pro features a Rockshox Pike 140mm fork with the unmatched Charger damper. A good fork is essential on a hardtail and the Pike delivers buttery smooth travel under all conditions, whilst staying composed even through sustained hits. Hope Technology provide the wheel set - a Pro 4 hub and Fortus rim combo, with WTB tyres front and rear. The finishing touches are our exclusive WTB Volt Race saddle in black and Burgtec Bartender grips.

  • The Bitmap hardtail frame was designed in Sheffield and developed on trails throughout the UK. As with all our bikes, it's built to be simple but effective. It's also fully up to date, with a Boost 12x148mm rear axle (included), integrated 180mm brake mount, a threaded BB shell and stealth dropper compatibility. Plenty of clearance for 2.6" tyres.

    If you have any questions regarding compatibility, please contact us.

  • We often get asked these questions so we've put together some quick answers for you. More information is available on our Tech Pages, Shipping and Warranty Pages.

    How long does it take to build a bike?
    Normally around a week for a standard bike. If you have custom options it can take longer but we make this clear in your custom build quote. Things can be a little slower at busy times, but we keep you posted on progress.

    Can I make changes to the build kit?
    Yes. All our bikes are built to order so we’re happy to customise for you. The best thing to do is contact us and we’ll produce a custom build quote for you.

    Can I have a different length dropper post?
    We put a 150mm Stealth Reverb on as standard, but if you’d rather have a 125mm or a 170mm Reverb, no problem. Contact us after you’ve placed your order to discuss.

    How much does shipping cost?
    Shipping costs vary depending on what you order and where you live. Take a look at our Shipping Page for more information.

    The size & colour I want is out of stock. Can I preorder?
