Pinnacle Dolomite 6 review

12 Jan 2018
Verdict:

A year-round workhorse whatever the conditions, and excellent value for money too

Cyclist Rating: 
Price: 
£1,150

Commuting, fast group rides, all weathers and big distances when the need arises… Pinnacle reckons the Dolomite 6 can do it all.

Wearing a Shimano 105 groupset and hydraulic brakes while currently reduced to £1,150, on the face of it the Dolomite 6 represents a lot of bike for your money. 

Frameset

The heat-treated aluminium alloy tubing is double and triple-butted for optimum strength-to-weight.

The ends of the tubes are rolled at their junctions in key areas, allowing the frame to employ a make-up that’s as light as can be where strength isn’t critical, yet durable and stiff in high-stress regions.

A 140mm head tube is matched to a sloping round-profiled top tube that provides a standover height of 743mm – plenty for all but the shortest of legs, in this the smallest frame size available.

The angle of the top tube makes for a compact rear triangle, which should make the most of power inputs.

Rangy chainstays, however, provide an amount of give in the set-up, boosting the comfort levels available.

The slope of the top tube also necessitates a long extension of 27.2mm seatpost, which again serves to dial out harsh vibrations from the road.

Although our test bike came with 25mm diameter tyres, Pinnacle claims there is clearance for 28mm rubber when the bike is fitted with mudguards (there are mounts for this, as well as for a rear rack), and as wide as 32mm without guards.

Brake and gear cables are routed through the frame, out of harm’s way, and we were particularly impressed to see a neatly routed front brake cable entering the fork top and exiting on the inside of the blade, rather than the oft-used (and clumsy) cable-tie arrangement that blights the aesthetics of many a disc-equipped road bike.

Groupset

Shimano 105 equipment makes up the lion’s share of the groupset, and there isn’t a better compromise between cost, performance and durability than this mid-level kit.

It accounts for the 50/34 compact chainset, the front and rear derailleurs, plus an 11-28 cassette.

The shifters are Ultegra-level Shimano RS-685 items, while the brakes themselves are RS805 calipers which bite on 140mm rotors front and rear.

Finishing kit

The Pinnacle wears a set of own-brand 420mm diameter alloy handlebars, matched to an 80mm Pinnacle Pro alloy stem.

It’s a short reach, but the taller hoods of the hydraulic shifters make for a longer stretch to the controls than with a standard caliper brake set-up.

An unassuming, yet effective, alloy seatpost has a diameter of 27.2mm; atop it, you’ll find a decent Pinnacle Race saddle, which is easily adjustable by way of a twin-bolt set-up.

Wheels

The bike’s Alex Draw 1.9S rims have an internal diameter of 19mm, so will easily accommodate a set of 32c tyres.

These disc-specific rims are also compatible with road tubeless tyres, giving the versatility to run them with inner tubes for fasting rolling performance.

Continental’s Grand Sport Race tyres, in 25c form here, are at the lower end of the German tread-masters’ performance road range, but they’re able winter companions – we’ve ridden many, many miles on these over time, with no cause to reach for a spare tube and minipump.

On the road

Although Pinnacle suggests its size S model is suitable for riders up to 5ft 7in, it was instantly a good fit for our 5ft 8in frame – if you’re short of leg, however, the low standover height afforded by the sloping top tube will give you a bit of wriggle room.

Either way, it’s worth visiting a branch of Evans to make sure you’re not between sizes.

Any fears of a buzzy ride from this alloy-framed mile-muncher are dismissed early in the day, as the combination of a long 27.2mm seatpost, carbon fork, and long chainstays allow us to make progress in comfort, with barely a vibe reaching hands or rump.

Running the Continental tyres at 85psi also makes a discernible difference, as minor road imperfections are simply rolled over with little fuss.

As we would hope and expect, the Shimano 105 groupset gels nicely, providing snappy gear shifts on the 11-28 cassette, and very well metered braking performance in damp conditions.

Although it weighs a relatively bulky 8.88kg, that figure doesn’t provide the whole picture.

The head tube is a relatively lengthy (for this size frame) 140mm, giving a comfortable riding position throughout testing, and crucially plenty of leverage when the need arose to shift our backside from the saddle (a surprisingly comfortable perch) and stamp on the pedals with a little more urgency in order to summit a local climb.

This isn’t a climber’s bike, specifically, but we can confidently say that it doesn’t feel like it’s nudging nine bags of sugar when it’s pointing up a hill.

The relatively close spread of gears on the 11-speed cassette gives you plenty to play with, while also supplying a big enough gear to make quick progress on rolling roads, too.

Handling

With a wheelbase that’s on the cusp of a metre, the handling characteristics of the Pinnacle tend towards the ‘stable’.

This is by no means a bad thing, as the bike is comfortable enough for a full day in the saddle, and approaches corners with encouragement and confidence.

The measured head angle of 72.2° is tempered slightly by the relatively long head tube.

With a riding position that’s just the right side of head-down, bum-up, the Dolomite provides a neutral ride that doesn’t have any nasty surprises up its sleeve.

The 25c Contis behave perfectly well, especially in damper conditions, where their wide footprint filled us with confidence to carve rapid arcs on our favourite local descent, while accidentally running over a manhole cover mid-corner gave no cause for alarm.

The brakes shine, offering progressive stopping power when it’s not an urgent request, and hauling up the rolling mass swiftly when we grab a handful of lever.

We reckon that, given there’s ample clearance for them, a set of 32c tyres would make this set-up even better suited to all-weather, year-round road use.

What the Pinnacle boils down to is a commendable road bike that will suit newer riders, as well as those looking for a dedicated rotten-weather workhorse.

And come the springtime, we wager you’d still be happy to swing a leg over its matt black top tube for a handful of early-season training rides.

Ratings

Frame: Strong and stiff but comfortable too. 9/10
Components: Mostly Shimano's superb 105 groupset. 8/10 
Wheels: Wide enough for fat tyres, and tubeless-ready too. 8/10 
The Ride: Stable but with a bit of zip through lively corners. 8/10

Verdict

This is a great bike not only for the winter but for year-round riding. You'd struggle to find a better equipped road bike for the money
