Specialized Allez Comp



Reliable, value-packed road bike that puts in a strong performance across the board. Certainly one to consider seriously at this price

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Last Sunday was the first weekend day that felt like spring to me, so I filled a couple of big bottles, put on some shiny new kit and headed out on the Specialized Allez Comp for my first 100-miler of the year. After a few hours on the back roads of Wiltshire and Berkshire, I came home thinking that this is a really neat, value-packed bike that deserves some serious consideration.

That wasn't the first time I rode the Allez Comp. Far from it. The bike arrived at way back before Christmas. Since then, I've got loads of miles in on it, and I've been consistently impressed. Here's why...


Dependable frame and fork

The Comp is made from Specialized's E5 aluminium alloy and the geometry is borrowed from the Tarmac series – it's the same as you'll find on the pro-level Tarmac SL3. Our review bike is the 58cm model and it's pretty rangy with a 582mm top tube and 44cm-wide bar.

The head tube (which is something I always feel the need to comment on; I'm obsessed) is 205mm and you get a 20mm cone spacer on top. It's the same as you'll find on the SL3, but when Specialized introduced their Tarmac SL4 full-on race machine they reduced the head tube length of the 58cm model to 19cm.


A Trek 2300 (£1,200) with a 586mm effective top tube comes with a 210mm head tube, and a Giant Defy 1 (£995) with a 575mm top tube has a 20.5 head tube – so Specialized are in step with other mainstream brands here.

When I first got on the Allez Comp, I felt that the front end was a little high for my taste. A few rides down the line, though, and I was perfectly happy and comfortable. Even on the flat road from Avebury to Devizes where the wind's always in your face – you must know it; you go past Bishops Cannings on your left – the position was low enough to slip along efficiently.


The welds are neatly done and the top tube bows distinctively. I don't reckon that makes a blind bit of difference to the performance but it looks pretty good. The bottom bracket is an outboard BSA type while the head tube is tapered, housing a standard 1 1/8in upper bearing and a 1 1/2in lower one. None of the other Allez bikes get this feature – they're all straight 1 1/8in. The fork that plugs in there comes with an alloy steerer and crown and carbon blades.

Without riding them all back to back I couldn't say for sure whether the tapered head tube provides extra front end rigidity but I can say that the Allez Comp is plenty stiff enough.


There's a super-fast descent by Broad Hinton White Horse. It's a left-hander we call Never Ending Corner because it goes on for a spookily long time. You think it's going to end... but it carries on. And then you have to throw the bike immediately into a right at 40mph+ without touching the brakes. Anyway, the Allez Comp's front end stayed perfectly well controlled down there and that's good enough for me.

Specialized say the Allez bikes have the same torsional stiffness as their Tarmac SL3 and I find that easy enough to believe. Fire as much power as you can muster through the cranks and everything stays aligned. The frame isn't as light as the higher-level road bike frames in the Specialized range, obviously – you're going to save weight if you jump to one of the carbon-framed Tarmac models – but the Allez Comp provides a performance that's just as dependable.


Super-value Shimano 105 groupset


The Allez Comp comes fitted with a Shimano 105 groupset that's hard to beat in terms of value for money. Manufacturers will often sling on a couple of 105 components and then save cash by fitting some downgraded kit too. Here, though, you get 105 shifters, brake callipers, mechs, chainset and cassette... that's pretty much a full house.


105 is arguably Shimano's best value groupset. Well, I say that; on another day I might argue that Tiagra is Shimano's best value groupset. Either way, you get a lot of performance for your money here.

What's so good? The shifters are really comfortable and flicking across the 10-speed cassette couldn't be easier whether you're on the hoods or the drops. I like the fact that the gear cables run underneath the bar tape to keep the front end tidy too. That's not the case with Tiagra or below.


Shimano do braking well and the 105 callipers provide a whole load of power. Shimano moved the brake lever pivot and the brake arch pivot on the calliper last year to bring them into line with Dura-Ace and Ultegra and the brakes now work better than ever.


As you'll know, there's that big hill coming down into Marlborough with a mini roundabout at the bottom. You don't want to brake unless you have to, but you can't see if there's any traffic coming until the last second. Well, these brakes give you the confidence to lay off the levers safe in the knowledge that you can stop in time if necessary. That's what counts in the real world.

Also, if you just need to scrub off a little bit of speed, like when you're coming down that twisty Stoke Hill just outside Erlestoke (the golf course side, not the prison side), the feel is good. Modulation through your trigger fingers is just right.


Speaking of Stoke Hill – it's the one that goes up to Salisbury Plain; only use old tyres if you're thinking of going over to West Lavington because the road isn't properly surfaced and it'll cut up the rubber – the compact 50/34T chainset matched up to the 11-28T cassette should get you up there without too much cursing. Be careful on the really steep bit under the trees if it's been raining, though, because any tyres can slip on that slime when you're riding out of the saddle.

There's really not a lot to moan about when it comes to Shimano 105. It's a bit vanilla, I guess. A bit like you'll find on a million other bikes out there... but that's because the performance is so solid and that has to be good news.


Specialized's finishing kit is well thought out


Specialized have a concept: smoother is faster. They've been using this phrase for ages. The idea is that if your bike is smooth you'll have more control, less fatigue, higher speeds, and you'll enjoy yourself more. It makes sense.


So, for example, the Allez Comp comes with a 27.2mm diameter alloy seatpost that flexes a touch more than a wider one to help tame road buzz. The skinny seatstays are designed to do a same job. Of course, it's virtually impossible to isolate the influence of each of these factors out on the road, but the Allez Comp is certainly a pleasantly comfortable bike to ride.

It's easier to feel the difference that the Body Geometry Riva Road saddle makes. It has a groove down the centre and a hole in the middle to reduce pressure on your 'sensitive arteries' (that's Specialized's phrase) – the ones that run to your... I think the medical term is 'tackle'.


It's fairly deeply padded and the shell flexes enough to handle any big hits that come your way. I felt comfortable on this saddle all day long during my big ride in the spring sunshine, even on that rough road that cuts through Savernake Forest.

Specialized's S-Wrap bar tape comes with deep gel padding that disperses any vibrations that get through the carbon-bladed fork. Okay, you could add decent bar tape to any bike for £10 or £15 but it's good to have it there from the start. I've done a whole bunch of rides of three hours or more on the Allez Comp and I've never felt uncomfortable.


Mopping up


Okay, so what haven't I covered? Ah yeah, the wheels. The Allez Comp rolls on DT-Axis 2.0 wheels which aren't available aftermarket, they only come as original equipment on complete bikes.


They're okay. They're not a highlight, but they're okay. They're still round and true, all the spokes are still intact and the bearings are running nice and smooth. Those bearings are of the cup and cone variety, by the way, so it's easy to open them up and give them a clean and regreasing as long as you have a couple of skinny 17mm spanners.

The tyres are Specialized's own Espoir Sports which aren't the lightest ever but they're grippy and the Blackbelt X2 puncture resistant belt has done its job so far in that I've not had to stand on the roadside changing tubes.

The only real negative in the Specialized's performance is that it's a tad overweight. Our 58cm test model hit the scales at 9.26kg (20.4lb) when there are plenty of sub-9kg bikes out there at this price; some a fair chunk under.


Of course, weight isn't the most important thing in the world but the Allez Comp would be a little quicker up the side of Milk Hill (the highest point in Wiltshire, dontcha know; although, to be fair, that's not saying much) if it lost half a kilo. It would be a touch quicker to react when you're sprinting for signs. It's not sluggish by any means and the frame stiffness helps with responsiveness, but a little lighter would be a bonus.

That said, what we've got here is a tough, very capable road bike that's going to be a faithful ride companion for years to come. The frame and fork are solid, the components are high quality, and the overall performance is strong. And that's why I came home thinking that the Allez Comp deserves some serious consideration.
