Superficially flawed if you judge it by componentry. But you shouldn't. The Tarmac offers a great frameset that would be, and is, suited to a far more costly bike

As the cheapest bike of eight in Specialized's Tarmac range, the base level Tarmac suffers in the parts specification stakes in order to make price room for a high quality carbon frame and fork. It's hard to fault its performance though.

Long established Californian bike brand Specialized have always followed the principle of allowing the technology they develop on top bikes to slowly trickle down to more price-accessible models. The entry level Tarmac gets the same SL2 FACT (Functional Advanced Composite Technology) carbon frameset as the Tarmac Comp, which costs £2500. Perhaps more significantly, it's almost identical to the frameset that the Specialized sponsored pro teams were using four or five years back. But does the cost-cutting parts package let it down?

This year's Tarmac range peaks with the £8500 S-Works SL4, with Shimano's Di2 electronic transmission. While the chassis construction of the SL4 may be slightly superior to the SL2 in terms of weight and stiffness, the more obvious variations to the average buyer are in the quality of the component parts. The base level Tarmac makes price room for the frame and fork by using far more cost-cutting parts than you might be used to seeing on a £1200 bike. They're all decent offerings that don't bump up weight too much, but there's no getting away from the fact that the Shimano Sora 18 speed gearset and a basic FSA crankset look a little out of place if you're comparing parts lists with the direct sales opposition rather than with other big name long established brands.

It's up to you to weigh up the pros and cons of buying mail order or buying an established brand offering from a local specialist dealer, but bear in mind that Specialized have a lot of R & D control over their bike packages compared to smaller less established brands so, when they boast about the construction of their frames, you know that they've already been used, abused and raced far beyond the capabilities of the average amateur rider.

The build of the Tarmac includes many features that have become familiar on carbon frames and a fair few others that are distinctive to Specialized. A long head tube makes for quite a high front end, emphasised by the 20mm spacer sat on the upper headset bearing, but if you like a lower bar position you can put the extra 25mm of washers above a downward sloping stem. Personally I used to like the cruising comfort of high, wide (420mm on the Tarmac) flat-top handlebars and levers when I had a few back problems but these days prefer a more stem-slammed-down posture as I rarely use the drops anyway. Both options are possibly on the Tarmac, but the combination of the head tube and upward-bowed top tube still makes for a lankier looking bike than some riders like. The curved top tube also leaves the rear brake cable sitting prone 10mm below the top tube.

The frame's 'tube' profiles are pleasing to the eye and undoubtedly contribute to a generally comfortable ride. Better quality wheels and tyres would improve this further: the V profile DT Swiss 1.0 rims and hard 23mm tyres (the harsher ride is the downside of the puncture-protection strip in the tread) are chattery on bumpy roads compared to the more upmarket wheels and tyres normally fitted to a chassis of this quality. I love the way the biaxially ovalised top tube form appears to flow straight into the rear triangle, and the slim slightly bowed seat stays undoubtedly add extra comfort to the back end, as does the small amount of vibration absorption in the carbon seat post.

A tapered head tube and massively oversized top and down tube junctures are created mainly to ensure precise steering and Specialized like to mention the way the carbon in the top tube and down tube wraps all the way around the head tube to create bulges for extra stiffness. The head tube on the more costly SL4 frame design has a smaller lower bearing than on last year's models, but a Tarmac SL2 has a 'standard' 1.125in upper bearing, 1.5in lower.

On the road, the Tarmac generally offers a level of performance that benefits from the classy chassis without being unduly hindered by parts compromises. Tipping the scales at a gnat's whisker under 20lb (about average for bikes at this price) it won't immediately give you an excuse for being left behind on the climbs, and the way the bottom bracket and chainstay form is constructed 'to optimise weight and stiffness' is noticeable when you get out of the saddle for climbs or sprints. The 32/24 spoked wheels (radially spoked front, radial plus three-cross rear) can handle a lot of power and bump abuse without flinching, despite their modest budget, while own brand Espoir Sport tyres grip slightly better than most other tough-treaded low budget offerings in the wet.

While it might be unusual to see just 18 Sora gears on a £1200 bike, the only moan that surfaced during the test period was related to the FSA Gossamer compact crankset: a subtle touch is needed with shifts under power because of the big jump between the 36 and 52 rings... and because the tooth profiles are not as clean shifting as on a Shimano drivetrain alternative. The big jump also means that more thought needs to be put into combined front and rear shifts... personally, I prefer 36/50 for this reason.

Braking duties are efficiently performed by the Axis DC 1.0 brakes and all the finishing componentry is decent quality house branded kit that does the job. I don't find Specialized's Riva Body Geometry saddle especially comfy, but the shallow drop bars felt spot on and I appreciated the gel padded bar tape. But bars and saddles are always going to be a personal thing.

If you don't like red bikes, Specialized considerately do a black Sport version, slightly better equipped, for £300 more. There are obviously loads of similarly priced bikes out there with better component parts, but everything here has a reputation for competent performance. The geometry is a fast reacting 73.5 degrees at the head and 73.25 at the seat (this varies slightly on the different sizes) and the 56cm test bike has a 530mm seat tube, a 565mm horizontal top tube reach and a lot of saddle rail adjustment.


Superficially flawed if you judge it by componentry. But you shouldn't. The Tarmac offers a great frameset that would be, and is, suited to a far more costly bike.

Seems like they should just sell the frameset and leave you to build it up with something decent?

snooks [31 posts] 5 years ago

This review is way too easy on Specialized and makes me wonder if it is that way to get advertising from them. The SL2 frame is ancient news at this point and is a frame that I can easily flex. Specialized also cheaps out a lot on components on a lot of their bikes using lower grade components for cogs, chains and brakes. They make good bikes but you can buy as good or better for much lower prices with full component groups. 4.5 out of 5 stars is ridiculous. 4.5 stars doesn't even fit some of what you said about the bike in this review.

Mat Brett [673 posts] 5 years ago

Um, snooks, it's 3.5 stars.

Lungsofa74yearold [293 posts] 5 years ago

Logic of this bike (and the review) seems to be it's either for someone who absolutely must have carbon (as opposed to a number highly evolved, better specced and much lighter aluminum framed bikes - Canyon, Rose, Cannondale CAAD 10 & Giant spring to mind) or as a donor bike to swap over expensive parts to. Personally, I think it looks good and the top tube and the head tube are sensible dimensions for old gits like me. But they really need to do something about that brake cable flapping around under the top tube...

nowasps [522 posts] 5 years ago

Can't believe they gave these five and a half stars.  13

Tony Farrelly [2963 posts] 5 years ago

five and a half stars is half a star more than full marks effectively 11/10 which would be good going nowasps, it got three and a half stars = 7/10. I'd say that's about right.

snooks [31 posts] 5 years ago

Ah 3.5 My aging eyes..the point still stands.

Yennings [237 posts] 5 years ago

Sora, schmora - it will wear out pretty quickly anyway and be ripe for replacement witIh something nicer. Frame should always be priority really, how many people could tell the difference between say 105 and Ultegra whilst blindfolded? Unless you're a serious distance cyclist (by which I mean RAAM-style distances) or a high-end amateur racer who wears out kit regularly, I reckon most people could probably get by perfectly fine with Tiagra in reality, if we could suspend snob value for a moment.

As for the frame, sounds ripe for upgrade although interesting that they've included so many comfort features, tall head tube etc. I always thought that's what the Roubaix is for and the Tarmac is aimed squarely at the fully-slammed racing crowd.

Personally I've always had a soft spot for Speccy. Bit ubiquitous but deservedly so. I would put them up there with the likes of Nike, Oakley and The North Face as mega US brands with all-conquering marketing machines who also spend a lot of the profits on R&D. Rarely going to be the very best products in their respective categories but always a solid choice.

typo on para 5:

Both options are possibly on the Tarmac,

jackh [121 posts] 5 years ago

Sora with a Tarmac frame just seems like a strange mismatch to me.

I'm sure Specialized know what they're doing, but is there really a market for a bike like this? A buyer who insists on carbon, but is happy to take Shimano's lowest end groupset.

racefaceec90 [33 posts] 5 years ago

i have the sport tarmac 2013 (my first proper road bike).i must say that i am very happy with it (am no racer though).

it is pretty comfy for a road bike,and have ridden it on the towpath (kennet & avon melksham to devizes).

i agree about there being better equipped bikes for less money,but the frame/forks are definitely well designed/made.

once i have finished paying it off,i intend to upgrade stuff on the bike (funds allowing) tbh i know that it is all the road bike i will ever need (way better than i am).

to finish with i will say that even though i am unfit/slow the bike does get a head of steam on when going for it (and it feels like it's transferring all your energy to the back wheel).it also feels responsive without you feeling like you need the reactions of a ninja (if that makes any sense?).

I was very lucky to buy the 2012 Tarmac comp for a very good price, £1400. I upgraded from my Allez 2012 same frame geometry as this one. All I can say is wow, the ride is so different, I did upgrade the front cogs to a 50/34 setup. As the bike origionaly came with a 52/36. And swap over my Continental tyres. The ride is a lot smoother, it accelerates a lot faster, so sweet to climb with. I' m thinking of upgrading the wheels next year, but for now I'm going to enjoy my new bike. But I'm not sure if I would have paid the full asking price?

Thank you.

brianc [3 posts] 5 years ago

I'm looking to upgrade from my Allez and i keep finding myself drawn back to this one, reduced price of 1080 just now.

I keep getting told to look at the boardman team carbon also. think i should go with my initial thought and go with this
