Pinnacle is an Evans Cycles house brand, and not one we normally associate with daring or outlandish designs. The Arkose Two’s bright green alloy frame is decidedly conventional with its threaded bottom bracket and slightly agricultural welds, but the build is virtually a one-off in its category, featuring TRP Hylex hydraulic disc brakes and a 10-speed, single-chainring drivetrain.
Highs: Great hydraulic brakes, and a full-carbon fork; its stock tyres offer good all-rounder ability
Lows: The drivetrain is noisy and there’s quite a bit of flex through the cranks and bottom bracket; the frame is quite basic too
Buy if: You want a sedate urban cruiser with hydraulic brakes that will do a bit of everything
The frame might be basic, but the Pinnacle has a tapered full carbon fork. It gets mudguard bosses, in keeping with the mounts for a rear rack and ’guard.

More on those brakes: Hylexes are currently the only way you can realistically combine hydraulics and a drop bar for less than a grand, and doing so means running a separate shifter – in this case a Microshift bar-end. Is it worth the trade-off? We think so.
The long hoods and sculpted levers are supremely comfortable but, more importantly, the power and modulation on offer borders on mind-blowing. That’s not to say mechanical brakes are inadequate, but the TRPs just feel so much better and the self-adjusting nature of hydraulics means you aren’t constantly having to compensate for pad wear.
The 1×10 gear setup has a pleasing elegance to it, but it runs quite noisily in the lowest sprockets. The chainline could probably be improved by spacing the chainring inwards. With 38 teeth up front and an 11-32 cassette the gearing might sound restrictive, but for general road riding and light off-roading we found it worked well.
Otherwise, the equipment is decent if unexciting stuff, with 32-spoke Alexrims built on generic cup and cone hubs. It’s good to see a Shimano 105 rear mech at this price and it marries perfectly to the bar-end, giving very tactile shifting. Our Arkose arrived with the hoods positioned low so the drops were awkward to use, but a quick bit of spanner work and bar tape rewrapping soon fixed that.

On the road the Pinnacle is well mannered and predictable. There’s a fair amount of flex through the basic Truvativ cranks and the square taper bottom bracket – this isn’t a bike that really rewards sprint efforts – but that’s not what the Arkose is about.
It’s great for cruising the streets, zipping down canal paths or exploring the odd bit of smooth singletrack. The 35mm Kenda Small Block Eight tyres (which actually measure less than 32mm) are excellent on packed dirt, and on tarmac they’re only a little slower than a slick; for mud we’d want something with more bite. Comfort-wise, there isn’t a lot of give in the frame but lowering pressures helps here. If you want more bounce, there’s room for substantially wider rubber.
The Arkose won’t suit everyone, but it’s a fun and unusual bike that’s good value for money.
