Specialized Rockhopper 27.5 Hardtail Mountain Bike 2022 in Red/White

Season:2024

Brand:Specialized

Code:291587303521

The Specialized Rockhopper 27.5 Hardtail Mountain Bike 2021 is now even better performing and better value than ever before! With suspension that works its hardest for everyone thanks to the size-specific Rx Tune, Specialized have baked in added performance to the all-new Rockhopper without dialling up the price. At its heart there's a Premium A1 Aluminium frame with butted tubes in order to keep weight low and strength high, and built with increased standover clearance, slick internal cable routing and dropper-post compatibility.

With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, Specialized have paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.

The SR Suntour XCE brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame size, while a durable Formula freehub and SunRace 8-speed cassette keep you rolling smoothly without putting up a fuss.

If you are looking for a quality entry point into mountain biking that doesn't break the bank, this is it.

Mountain Bike Sizing Guide

Mountain Bikes tend to use the T-Shirt sizing of S, M, L etc. or will have the seat tube measurement in INCHES. Why mountain bikes are inches and road bikes are CM who knows, but the part of the frame being measured is the same.

As a rule of thumb if you can identify your size as Medium on one brand, you should use that as a starting point on another brand too.

If you already own a medium mountain bike for example and are comfortable with the sizing, start there.
 

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (14-15")
5'2" - 5'6" 158cm - 168cm Small (15.5-17")
5'6" - 5'10" 168cm - 178cm Medium (17.5-18")
5'10" - 6'1" 178cm - 185cm Large (18.5-20")
6'1" - 6'4" 185cm - 193cm X-Large (20.5-22")
6'4" - 6'6" 193cm - 198cm XX-Large (22.5"+)
