Features

An over-sized monster of a bike that goes against the grain and proves that fat is fast!

Calibre's Dune is a great value fat bike designed specifically to tackle UK trails, while still being a great choice for shredding across snow and sand.

We've taken standard fat bike geometry and tweaked it for faster, more aggressive riding in normal UK trail conditions. The Dune frame realises this geometry with an incredibly light, strong aluminium frame with huge clearance for big tyres and lots of mud. Hand-welded throughout, it's an incredible frame that makes the most of fat tyres' natural suspension and deserves to be ridden hard.

Weight is an issue since the wheels are so much wider than normal, which is why we use lightweight aluminium rims with cutout sections for even lower weight. Seated on these rims are a pair of Kenda Juggernaught Pro tyres*, one of the most popular fat tyres on the market and lighter than those used on the original incarnations of this stunning bike.

Making these wheels spin is a 2x8 Shimano drivetrain with a wide-ranging 11-34T cassette providing a huge spread of gears for varied terrain and conditions. Shifting is smooth and responsive across the entire 16 gear range thanks to advanced technology trickled down through the years from Shimano's pro-level XTR system. Powerful Tektro HD-M290 mechanical disc brakes take care of stopping power with 160mm rotors front and back.

The Calibre Dune slashes the pricetag while maintaining an incredible specification, giving you the perfect opportunity to get into fat biking and add another bike to your stable without breaking the bank.

 

*Please note the images are for illustrative purposes only, the Dune Bike comes with Kenda Juggernaught Pro tyres and NOT Schwalbe Jumbo Jims as shown.

History of the Fat bike

Fat bikes have taken the mountain biking community by storm over the last few years. Fat bikes are mountain bikes with huge 4-5" tyres run at very low pressures. They were originally designed for use in snow and sand where the big, low pressure tyres float on the surface, letting you ride in conditions when your tyres would normally sink and get stuck.

Now people have realised that the big tyres provide a sort of natural suspension and that they are great fun to ride on normal trails in normal conditions too. The big wheels simply soak up bumps and roll over obstacles that might upset normal mountain bike wheels. The low pressure tyres also mean a unique, fluid riding style that is incredibly fun and unlike any other kind of mountain biking!

That's the kind of riding that the Dune has been designed for.

Great value but 14.4 instead of 13.2 kg, 20 November 2016
By Lachman (Poland)
Important info for those hoping for a truly lightweight fat bike - my size M bike weighs 14.4 kgs, not 13.2 as specified on the website. Not a big difference but still...

Some quick observations after 40 kms in mixed terrain and 50 kms on the beach:

- size M frame is OK for riders up to my heght (179 cms), taller people should choose size L;
- build quality seems very good;
- the drivetrain is quite acceptable, I don't think you really need anything much better in a bike like this;
- one info missing from the website is the size of chainrings: 36/24T
- the weakest part of the bike are the brakes. Perhaps it's about adjustment, but so far the rear brake works well, the front is too weak for any serious descents.
- the tyres (Kenda Juggernaut Pro) are very light, but also appear not very durable and seem to have quite high rolling resistance. I was able to ride 27-28 km/h on flat tarmac but only with significant effort. On slightly wet beach sand I was able to average 15 km/h with about 0.7 bar (10 psi);

So much for the first impressions, will add a longer review after riding some more.

Fun fatty fun, 07 November 2016
By ssnowman (London)
Brilliant. Without doubt the best VFM bike I have ever bought. I'm not saying it's perfect, the drivetrain is obviously low end and shifting is not the smoothest, but I'll run it as is until it needs replacing. The cable discs aren't as bad as I thought they would be and I intend to see how i get on with them for now. It's really put the fun back into mountainbiking for me. The frame, forks, wheels and tyres are standout items and the overall weight is a lot lighter than anticipated.

what a bike for the price, 24 September 2016
By WallyG (west yorkshire)
love this bike. value for money is just to good to be true.
rides amazingly.
had on one 45650b and this bike is lighter and have gone down stuff I wouldn't have done on the 45650b that cost 3 time as mush. I am faster up and down hills.
I have now upgraded the running gear and it is even better gone 1 b 10 30t front 11-42 back shimano deore brakes. works like a dream this is now my only bike.
also converted to tubeless nicely.
cant get enough of riding it.
you will stand out. every ride I have been on in the 6 months someone has asked about the bike.

I have 7 bikes, this is my favorite!, 07 September 2016
By The King (Blackburn)
Hugely impressed with everything about this bike, phenomenal grip, I've not found anything i cant tackle yet, and its a really comfy position to be in for the more technical descents. Coupled with a pannier and handle bar bag, I've had some fun wild camps track side, before hitting the trails again in the morning.
Definitely recommend this to all of you!
