45650b

650b Hardcore Hardtail

Overview

The Original 650b Hardcore Hardtail

The 45650b is a quality steel-framed 'ride-anywhere' hardtail mountain bike. Featuring specific geometry for 650b wheels, handling is more agile than a 29'er, whilst also rolling faster than a 26'er. With the 45650b you really do have the best of both worlds.

A double-butted steel frame gives the 45650b serious strength and durability, as well as smoothing out the rough stuff like only a steelie can. The 45650b can run 4, 5 or 6 inches of front fork travel - hence the name! - which is ideal for speedy flats and descents. We've also included an ISCG mount around the bottom bracket to eliminate chain drop. Nifty!

As a package, the 45650b represents massive grins for your money. Superb groupset options, quality disc wheels and first-class finishing kit combine to give you a bike that's ready for anything.

  • Capable All-Round Hardtail
  • Double Butted Cro-Mo Frameset - Strong & Durable
  • RockShox Front Suspension
  • Quality 650b Disc Wheels
  • Agile Geometry
  • Multiple Groupset & Finishing Kit Options

Features


The Hardcore Hardtail Updated

Earn Every Descent

The Ride Of Your Life

The 45650b takes on the whole mountain and goes further than you ever imagined. Based on our legendary '456' hardtail geometry, the 45650b adds in 650b wheels to retain nimble and surefooted handling for prowess on the descents, plus adds a lot more speed!

Drive up climbs, skip through singletrack and descend like a demon, that's what's in store with the 45650b. No other hardtail delivers the same rewarding ride characteristics; nothing can match this performance for the same money.

Double Butted Durability

Hand Welded

Steel Like No Other

The 45650b features hand-welded DN6 double butted cro-mo tubing. Robust. Quality. There's also an externally butted seat tube to provide maximum support for aggressive riding and help trim the fat. Headtube junctions are beefed up with external gussets for ultimate strength and we've even fitted an ISCG mount for your favourite chain guide / bash guard.

It's steel. it's real. What else would you expect from Sheffield's own bike company?
