Sab La Rocca Shimano Tiagra Road Bike £599.99 at Planet X

36
Found 24th Sep 2013
I've been trying to find a really decent road bike for a £599 budget and thought I would share this one that Planet X have just started doing. I want a bike that needs no additional money spent for a few years on upgrades so must be great "out of the box".

Its a 9.1 Kilo road bike, part carbon fibre Triple butted frame, decent wheelset for the money, Tiagra gears, decent finishing kit, prologo saddle. I think this bike is a good contender compared to the Btwin Triban 7A from Decathlon and the Corratec Dolomite 105 from Chain Reaction. Theres not a lot to split the three bikes, I think based on the large frame its the following weights(without pedals)

The Planet SAB La Rocca is 9.1Kgs
DecathlonBtwin Triban 7A is 9.4Kgs
Chain Reactions Corratec Dolomite 105 is 8.94kgs

Would be interested to hear what others think of these three bikes and how they compare

Thanks for posting. I’ve added the price to the title.
Here’s a ‘Help’ link which gives tips and advice on thread posting.

It is not my subject but I think Hukd need subject knowledgeable people like you , so as courtesy give you heat .

This is a good price for a starter road bike.

I am looking to get the frame on its own as a winter bike and build my own. Heat added for the frame.

Seems a decent alternative to the B'Twin but an unusual move to go with carbon seat stays instead of fork

Hope you get some answers as I have been looking as same price bracket - in particular the triban 7.
Currently use a hybrid, not sure if start of winter :-( is a good time to buy a new bike, lots of discount ATM though and I am sure these hills in North Wales are getting steeper:-)
Is Sept\October usually when best discount given? Though if wait longer guess some will go out of stock. Bargain / bike hunting not simple at times:-)

Voted hot by the way.

Looks okay.
Though, not sure about having an alu fork. Could be a bit of a harsh a ride unless you have a fat/supple/low-pressure front tyre, and that may still not be enough - just my experience of them.

That said, the CRC Dolomite you mention is mostly 105 - so 'higher' spec.

Out of the 3 you list I'd get the Dolomite.

its not Alumiunium fork. its carbon. if you click 'more info' next to the frame details it shows it has a matching carbon fork.

Okay. It's just that the linked page on PX's site says "Fork: SAB La Rocca Aluminium Fork".
You are talking about the frameset by itself?
Maybe PX goofed their description and mean carbon + alu steerer fork?

OP should ask them to clarify if still interested.

Lol, half a kilo. You could lose more weight than that going for a dump. Worry about the weight when you're doing the Tour De France. Until then just be happy knowing that on a more expensive bike you'd be going 0.5mph faster.

Imagine you're a bit lighter after dumping that comment

great bike but id go for the btwin for decathlons after service,which,in my experience is superb.

Great bike for the money, but as with a lot Planet X bikes, just misses something; in this case, calling it a winter bike with no mudguard/fender mounts, pretty essential for UK riding, but using something like SKS Raceblade Longs

Good … Good review?http://www.bikeradar.com/gear/category/bikes/road/product/review-corratec-dolomiti-105-09-34031

The model in that review had better wheels though (by the looks of it). Wheels usually seem to be the first thing I want to upgrade

The Triban 3 has carbon forks, isn't especially light but... is £200 cheaper. It is ok, not great but Ok.
My comparison

Oh and taking about weight; as my kindly uncle said to me, you needn't look to spend good money lightening a cheap bike - ride the damn thing every day and lose weight from your butt.
That's where all the weight really is.
Thanks Unc

I own the Triban 7a and can't recommend it and Decathlon enough. For spec/budget/service I am very impressed indeed. Very comparable to this and seems decent enough, not sure there is much weather left for it mind you!

I would suggest having a good think about one of these:

evanscycles.com/pro…963

They get the best reviews typically. Comparing specs is one thing but what specialised are good at is producing a well balanced bike that rides well. It will also hold its value well if you come to sell it. You are far better of test riding a bike + making sure it fits and you like it than getting taking a punt on one.

Best of luck with whatever you end up doing mate.

ooo another one to chuck into the mixer. there seems to be suddenly a glut of decent spec bikes about at the 600 pound mark. wiggle.co.uk/ver…13/

Not bad but you can get a better spec bike second hand from eBay usually upgraded for a cheaper or similar price if you have a look about. Got an allez sport with full sram rival, look keo peddles armadillo tyres and Mavik askum wheel set for £420. Just a thought. Heat added though.

Not sure about the Allez, 2300 is not a great groupset and even Sora is a step up from it. Judosteffer is correct that £600 is a pretty standard price at this time of year for a 'budget' Tiagra ride. The challenge is finding your size. Rutland Cycling have a 105 equipped Giant TCR reduced from 1250 to 799, which is an absolutely storming deal for a really, really good bike. My top pick at the moment.

That is a real tempter, but I'm very wary of 'buying without trying' these days regarding size, if you can sit on one in your LBS great but I wouldn't advise anyone to buy a bike blind, it's a costly mistake I've made in the past.

I'd be tempted to not get an Allez with a 2300 groupset unless you really are not sure if you want a road bike and might sell it on within a month or two. I own an Allez double (although I paid £350 for it brand new a couple of years ago) and the group set is quite frankly a bit pants, LBS have said they can upgrade me to Tiagra for £375.... I had to replace wheels on it as the ones that came with it were not really up to much, the frame and bars are quite good though but to get that bike up to Tiagra spec isn't worth it as you'd be better off spending £800-£1000 up front.

I've got a Giant TCR, although not the same as this one and it's an awesome ride.

looks ok , bit strange carbon rear end but not front !???

so well worth it ...if you are a pro/very serious. Other thing of course is the possible enjoyment when using better quality kit. Same as timex versus omega - both tell the time pretty accurately.

it has a carbon rear triangle and a carbon fork, it looks like P-X have messed some of the descriptions up.

Exactly, how often can an increase in quality in a consumer item be measured objectively? My summer pride and joy is £2.5K worth of carbon fibre. Does it make me quicker than a £500 bike? Possibly, but only because it makes we want to ride.

This looks like a stonking deal for a new bike, and the frame/fork package is really good value too (assuming its decent quality).

Are roadies never satisfied? You're always on about how another bike is better or how you need to put carbon forks and better wheels on it, you don't even ride it if there's a drop of rain!

The traditional view is that carbon can be made as stiff as aluminium for less material (if laid correctly), or that you can get better damping because you can lay the carbon the way you want. The reality of carbon components in the rear triangle is that they are probable extruded carbon rod cut to length and bonded to the aluminium with no particular eye to the precise structure of the component, they could be for show, you might perceive that the ride is improved, it's really personal preference (although note, Carbon and Aluminium can corrode when poorly joined due galvanic effects - exercise your carbon seat post now and again!).

This is why the general 'stiffer than' argument is a little bogus because it all comes down to design, you can make an aluminium frame as stiff as a carbon frame but it needs more material, that said, a carbon frame can be made stiff and light but not necessarily strong in all areas (think of a frame designed to be stiff in compression hitting a rock when it falls on its side causing de-lamination, a dent in an Alu frame may not be a big deal, de-laminated carbon can be hard to spot and could lead to a catastrophic failure).

Also, not all carbon is created equal, manufacturers use different grades of CF, differing ratios of CF to resin and different layup techniques depending on the price point they want to meet - that's why a cheaper carbon frame may not me as light as the best aluminium frame. You can get Alu bikes that come under the UCI's minimum weight.

As far as the aero steeds, most of the aero shapes that you can achieve with carbon couldn't be achieved with aluminium without much additional material adding weight. It's on the TT style bikes that carbon really shines - if you're in the market for anything sub £2000 you can do just as well with aluminium as carbon (dependent on your personal preferences), the market has just pushed manufacturers away from boring old Aluminium to sexy new Carbon - that's marketing for you.

Really the carbon vs aluminium argument comes down to two questions - budget and preference.

If you have a high budget (£2000+) go for carbon, it's the way of the future and you'll get a frame made of high-quality material.

If you have a budget below £2000 then look at both, these days you'll find more carbon then aluminium because it's where everybody is heading but that's not to say that an Alu frame is inferior at that price point - you may well find that a manufacturers best Aluminium frame is quite a bit lighter then their cheapest carbon frame.

If you're around £1000 then beware of carbon, it's not to say that the frames are no good, I'm sure the Planet X frames are fine, but you'll probably do just as well with Alu - you just won't have the new hotness. You can justify your decision in the pub at the end of the ride. Don't listen to the 'it's made in the same factory as' arguments. Industrial autoclaves are expensive, as is CF processing, so all manufacturers will outsource. It's all about the material in the frame you're buying at the end of the day, not the material in the £5000 Look frame that was made beside it.

I still think you'll struggle to find a carbon framed bike under a grand unless it's on sale, if it's new and under £1000 I'd be wary of carbon and go with the devil you know!

Nothing against Planet X though - They've done a lot for UK cycling getting decent kit into peoples hands, I've got a set of their AL30 wheels and they're amazing for the price, generally their bikes seem to be very good value and I've been very tempted a number of times - their margins must be razor thin!

As for the 'why pay a fortune to loose weight' argument, first you have to consider the center of gravity of the rider vs the bike, but mostly consider that a .5 mph difference won't change your ride to work, but in a short 30 mile race at an average speed of 25mph or so you'll finish around half a mile in front of your opponent. In a mass race, where there will be drafting this still might not be significant, in a triathlon going into a run a half mile advantage is massive!

Strong, Light, Cheap - Pick 2.


Good though the Ribble Alu/Carbon bike represents a better deal and you can spec it for extra with your choice of group set...

thanks everyone for the constructive comments and all the suggestions! sounds like its definitely a good time of year to get a road bike!

bikeradar.com/gal…7/3

This is my TT bike ,although iv got bontrager disc..:3

Youll save a kilo maybe with carbon ,but mainly better damping perhaps on longer courses..

iv only used it for sprint triathlon

I'm surprised that this is getting colder. It's still an excellent deal with a great spec for the price.
