HIGHPOINT A2

Jamis bills the Highpoint A2 as a true all rounder and it’s easy to see why. With big 29in wheels to roll over bumps better and a 120mm travel coil-sprung Suntour XCM 32 fork to take the edge of the harshest impacts, it’s designed for speed, but not at the expense of comfort.  Best hardtail mountain bikes: classic trail-shredding machines Comfort, which is enhanced further thanks to the triple-butted aluminium frame. In fact, the Highpoint A2 offers a more forgiving ride than the Carrera, even though both bikes have the same 2.25in width WTB Trail Boss tyres fitted.  The frame also has a tapered headtube, even if the fork still uses the older 1 and 1/8in straight steerer tube. Not that you can tell when riding however, as the front end feels solid and direct. Bolstered, no doubt, by the stiffer bolt-thru dropouts on the fork.   Cable routing on the Highpoint A2 frame is a mix of internal and external and it desperately needs sorting. The gear cable rattled inside the downtube and one of the C-clips that secures the brake hose under the top tube popped out on the very first ride. As such, we replaced all of the C-clips with zip ties and suggest you do the same. We’d also recommend sawing a couple of inches off the seat post, as we couldn’t lower it more than 40mm for descending. Thankfully, the frame has routing for a dropper post, so ultimately an upgrade would be the best solution.  Best mountain bikes under £1000: reviewed and rated by experts Suspension With 32mm chromed steel upper tubes and a 15mm bolt-thru axle, the Suntour XCM 32 fork provides good steering precision and confidence under heavy braking. It’s coil sprung, and slightly over sprung for an 80kg rider which makes it nigh on impossible to achieve the full 120mm travel. That’s no bad thing here though, as it helps maintain balanced geometry and is preferable to it being under sprung. Not least because the cap that holds the spring in place is made from plastic, so swapping a spring, if you can actually get hold of one, could be tricky. Overall the action of the fork is rudimentary. It works, but the friction damping really lacks finesse. Components Thankfully there’s nothing basic about the Shimano Deore 10-speed transmission. It delivered smooth, fast, accurate shifting every time. And because of the clutch mechanism on the derailleur, chain noise is dramatically reduced. Jamis has missed a trick with the gear ratios though, the lowest (easiest) gear with the 32t chainring being the 42t cog on the back. For an all purpose 29er, we’d like to see a 30t chainring or, better still, a wider range cassette to make harder rides easier on tired legs.  Tektro’s M275 2-piston brakes are consistent, but don’t offer the same amount of stopping power or modulation as the Shimano units on the Carrera or the Clarks brakes on the Vitus Nucleus 29 VR.

A well-specced hardtail with an impressive fork for the money, but the geometry leads to a few quirks that take time to get accustomed to
