Step into the world of mountain biking, or take your riding to the next level with the Specialized Rockhopper Expert 29” Mountain Bike 2017. Constructed with Specialized’s A1 SL Aluminium, the frame is incredibly stiff and efficient for long distance rides, whilst the Manitou M30 29” fork absorbs bumps and vibrations without affecting your comfort.

Specialized Rockhopper Expert 29” Mountain Bike 2017

As the workhorse in the world of mountain biking for decades, the Specialized Rockhopper has been the go-to mountain bike for everyone from beginners to professionals at one time or another. Its solid, dependable frame and capable components let riders explore the great outdoors and take on as much, or as little, that the countryside had to offer. Now, the Specialized Rockhopper Expert 29” Mountain Bike 2017 has been redesigned, and this is the result.

A lightweight, strong and durable frame is at the heart of the Rockhopper. Constructed with Specialized’s A1 SL Aluminium, which boasts a great compliance to rigidity ratio, the bike can provide the comfort you need on long rides in the countryside, whilst also the efficiency to put down the power and climb when you need to. The SL Aluminium is also corrosion resistant, meaning no matter what weather you ride in, the bike will be protected from the elements.

The entire bike has been focused around the 29-inch wheels. The 29er offers great rolling ability over roots, rocks and bumps when exploring rough terrain, whilst also improving stability and consistent speed for a more enjoyable ride. Specialized have incorporated their Ground Control Sport 29 x 2.1” tyres to compliment the 29er choice, enabling great puncture resistance and ample levels of grip in the corners, climbs and downhill sections.

A Manitou M30 29” fork with 80/100mm of travel controls the shock absorption on the Rockhopper Expert. This fork features Trail 29 geometry, ensuring everything is perfectly suited for one another and allows you to maneuver through adverse terrain in comfort, absorbing big hits with ease.

When riding off road, you never know what may lay ahead and that’s why you need a wide range of gearing to get you up those testing climbs. Specialized have incorporated their SRAM X5 front derailleur and Shimano SLX rear derailleur for this, ensuring you don’t run out of steam when heading up the mountains.

Shimano BR-M365 hydraulic disc brakes control the braking prowess of the Rockhopper Expert and are also highly reliable when heading off-road. A combination Shimano Deore, 10-speed lever allows you to access the full potential of the gearing and braking, with its ergonomic shape that contours to the curve of your fingers.

The Specialized Rockhopper Expert 29” Mountain Bike 2017 is an ideal choice if you’re looking to take your off-road riding to the next level, exploring the unknown and tackling much more technical terrain.


  • The frame is constructed from lightweight A1 SL aluminium in order to provide a compliant, durable platform to support our acclaimed Trail 29 Geometry. Combined, you get a bike that's more than efficient on climbs and eager to get down to business on descents

  • A Manitou M30 29 fork offers 80/100mm (size-specific) of plush, trail-taming travel and stiff 30mm stanchions

  • It's hard to beat the blend of durability, reliability, and performance that the Shimano SLX rear derailleur provides. It's designed to take a hit, and more importantly, its shifting is crisp, precise, and always on the money
