Product Description

Discover the joys of the trail. The Specialized Rockhopper Comp is a hardtail mountain bike that is quick up the climbs and confident on the way down. The lightweight aluminium alloy frame has dialled XC/trail geometry while the 29” wheels are fast rolling on both rough and smooth terrain.

Key Features:

  • A1 Aluminium alloy frame is lightweight and robust
  • SR Suntour XCM fork for 100mm of bump soaking suspension travel
  • Shimano 2x9 speed drivetrain for a wide gear range
  • Shimano hydraulic disc brakes for powerful stopping
  • Sizes: X Small, Small, Medium, Large, X Large
  • Colours: Gloss East Sierras/Tarmac Black, Gloss Storm Grey/Rocket Red/Tarmac Black
  • The Specialized Rockhopper Comp is available with 0% APR finance

Whether you've been riding trails for decades or you're just starting your XC journey, the Rockhopper Comp 29 is here to take your rides to the next level.

It starts with our new A1 Aluminium frame that has optimized tube shapes that save weight while dramatically improving aesthetics. To go along with these clean new lines, the new Rockhopper also has internal cable routing to further clean up the frame. Lastly, our Sport XC 29 geometry adjusts the reach, angles, and standover height to make for an improved fit across the size range. This is sure to keep you ripping and confident while heading both up and down the trail.

This Rockhopper comes with a no-nonsense spec featuring a mixed Shimano drivetrain, dependable Shimano hydraulic disc brakes, grippy Ground Control and Fast Trak tires that add traction over any trail, and an SR Suntour XCM 29 fork with our custom Multi-Circuit damping that eliminates the "pogo" feel commonly associated with coil forks.

The frame is constructed from lightweight A1 aluminium in order to provide a compliant, durable platform to support our acclaimed XC Sport 29 Geometry. Combined, you get a bike that's more than efficient on climbs and descends just as well.

The SR Suntour XCM fork puts out 80/90/100mm (size-specific) of plush and reactive travel, provided by coil-sprung suspension that's custom-tuned for lighter riders.

A Shimano Acera rear derailleur controls the rear shifting with durable aplomb. It shifts along a wide gear range, 11-36t, so you can ride confidently knowing that you'll always have the right gear for the hill at hand.

Just A couple of changes

I have just replaced my Rockhopper comp 2010 with this 2019 model and first impressions are very good, it is as you would expect built exceptionally well, the finish quality is excellent. It rides very well and is well balanced. The Suntour forks are Unfortunatly a bit of a let-down, the 2010 came with entry level Rockshox and were great, the suntours are not. I have replaced them! The new gearing was a bit low, but this does seem to be the industry standard, I see this has already been commented on, but to be honest I changed the front rings and went with a 40 tooth outer and I don’t find myself searching for another gear anymore on the downhill sections. Overall in my opinion its great value for the money, I think I would prefer to buy this model and upgrade to the parts I want with the money saved Not forgetting when you but Specialized you buy an amazing customer service and guarantee. (I speak from experience) Cheers Arch

Playtime

Got this as a playtime hardtail and commute bike.the stock fork is useless. Swapped for a rockshox recon and slapped on some riser bars .shortened the rather lengthy stem to 35mm...now I’ve got a playful hardtail worthy of the ROCKHOPPER lineage! The Xxl frame is only just big enough for me but with the changes it rips. Saddle , gears , brakes all ok at this price point .listed in the trail section on the main specialized site , not just an Xc bike. A spritely trail 29er!

MTB Hardtail Guide

 

Is a Hardtail mountain bike right for me?

If you’re new to the cycling world, we highly recommend taking a look at our bike buying guide overview or our mountain bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a hardtail mountain bike, there are a few things to look out for which can help you to work out the quality and performance you can expect from a particular model.


Usage and suspension travel

Depending on the type of mountain bike riding you’ll be doing, you will want a bike with a longer travel or shorter travel suspension fork as well as components suited to more or less technical terrain.

Frame Material

Hardtail MTB frames are mostly made from aluminium alloy. High-end cross-country race bikes will have carbon fibre frames while trail hardtails and jump bikes sometimes feature steel frames.

Aluminium

Aluminium alloy frames are strong and lightweight. More expensive alloy hardtail MTBs tend to have ‘butted’ and/or formed frames which are lighter but just as strong.

Steel

Steel frames are heavier but offer a more comfortable ride, especially on higher end models, thanks to the more compliant nature of steel.

Carbon fibre

Carbon fibre composite frames offer the best of both worlds as they are strong, lightweight and comfortable. They are more expensive however and carbon hardtails start at around £1,300


Groupset and Drivetrain

A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen. A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifters
  • Front & rear derailleur
  • Chain
  • Cassette

Mountain bike groupset components are typically supplied by either Shimano or SRAM, with additional manufacturers like Formula, Hope, Magura, Tektro and TRP supplying brake systems.

Shimano & SRAM both produce a range of groupsets to suit different budgets. The hierarchy table here compares the different Shimano & SRAM groupsets to determine which bikes offer the best performance. 

Groupset comparison - Shimano & SRAM

What gearing options are there?

Most hardtails offer a wide range of gears for taking on a variety of terrain. It’s not all about the number of gears though as fewer gears on the front, combined with a wide range rear cassette are much easier to use, but still give you the same wide range of gears. As you go up the price points shifting gets easier with more cogs on the rear cassette and fewer front chainrings.

Entry-level hardtails will have a triple chainset with a seven (3x7) or eight (3x8) speed cassette

Mid-level hardtails tend to have a double chainset with a nine (2x9) or ten (2x10) speed cassette

High-end hardtails get a single front chain ring with a ten (1x10), eleven (1x11) or even twelve (1x12) speed cassette

Which are the best brakes?

There are three types of brakes found on most hardtail mountain bikes:

Rim brake example

Rim brakes are powerful in the dry but are significantly less powerful in the wet.

Mechanical disc brake example

Mechanical disc brakes are powerful in all weather conditions

Hydraulic disc brake example

Hydraulic disc brakes are the most powerful in all weather conditions, and also offer the best braking precision.


Wheel Size

You’ve probably noticed that mountain bikes come in a choice of wheel size, mainly a 27.5 inch wheel (also known as a 650B wheel) or a 29inch wheel (known as a 29er). Another option is 27.5+ or 6Fattie wheels which bridge the gap between 27.5” and 29” wheels. The traditional MTB wheel size is 26”, but are now only found on some small sized MTBs as well as jump bikes. The difference between these wheel sizes can have a dramatic effect on the way a bike feels and handles out on the trail.

MTB wheel sizes

27.5” (650b) wheels strike the ideal balance between fast rolling and nimble handling. They are lighter than 29” wheels so are faster to accelerate. On the other hand, the smaller wheel size rolls less efficiently than the larger size, making the bike more prone to losing speed over rough ground.

29” wheels roll fastest but are less nimble. These wheels are naturally smoother over rough ground but are heavier and slower to accelerate. Larger riders may find a better fit on a 29er, but smaller riders may find 29” wheels a little cumbersome.

27.5+ (6fattie) wheels feature wider 2.8” – 3.0” tyres and offer more cushioning (float) as well as more grip. With the extra size of the high-volume tyres, the overall wheel diameter is similar to a 29er so these wheels carry speed very well on rough ground. Plus sized wheels are ideal for riding more challenging terrain.

26” wheels are the nimblest and are great for smaller riders as well as jump bikes. While quick to accelerate these wheels are the slowest over rough ground.

Does tyre width make a difference?

Tyre width effects both speed as well as grip. Narrower tyres are faster rolling while wider ones offer more grip as well as more cushioning (float).

Recreational tyre example

1.95” - 2.0” tyres roll quickly and are good for recreational riding and light off-roading.

Trail tyre example

2.2” - 2.6” tyres are a little slower on smooth surfaces but offer much better grip in the corners and are ideal for MTB trail riding

Plus size tyre example

Plus size (6fattie) 2.8” – 3.0” tyres increase the overall diameter of the wheel so still roll quite quickly while offering a lot more grip and float. These are best for rougher terrain


Suspension Fork

The performance of suspension forks varies a lot. Forks on higher end bikes tend to offer more control and are more adjustable. Look for Fox, RockShox or Manitou forks with adjustable rebound and compression damping for the best performance on technical trails. The performance level you require will depend on what type of riding you want to do. 

For recreational riding on roads and gravel tracks, you won’t need a high-performance fork. A lockout feature can be useful for more efficient climbing on roads and smoother tracks. Air sprung forks are lighter than coil sprung forks.

For cross cross-country mountain biking lightweight air sprung forks are best. Adjustable rebound damping is essential for serious off-roading and a remote lockout switch will allow you to quickly firm up the suspension when climbing.

Trail hardtails feature longer travel suspension forks for riding on rougher terrain. Adjustable rebound damping is essential for control on challenging trails. Lockout is less important on these bikes as they are catering for riders who like the downs more than the ups. Adjustable compression damping is useful as it can help you achieve optimum performance levels. Thru-axles and tapered steerer tubes improve steering control.
