    Hello everyone.

    I have been following the forum for a while and learned a lot here (thanks!) but this is my first post. I started daily commuting in London some years ago and have been riding an hybrid Tachyon GT 4. I have done quite a few thousand miles on it and enjoyed changing various parts as they gave up the ghost.

    I think I am ready to try a road bike. I’d go for alloy but I can see the price of carbon frames has plummetted while I was learning to cycle, so I am quite tempted. I see many here stating that the RX-58 Carbon by Planet-X is a perfectly OK frame. Can I check with you whether this comment applies to someone heavier than average (90kg) who would need a fairly comfortable bike? I do 15miles daily without a problem and want to do longer stints at weekends.

    If the frame is fine, can I ask you for advice between the

    Shimano or or Sram? Both at £799 right now.

    I’ve been with Shimano on previous bikes but they were cheap groupsets so I guess these are completely different pieces of kit.

    Thanks!

    Doom and gloom old fishwives? More than happy to provide photographic evidence to back up the broken frames I described. I don’t care what people ride, I just think people should know what they’re getting for their money.

    Yes they’re cheap, for a reason.

    I just thought that I would add my twopence worth regarding PX RT58 Carbon. I cycle around 6 or 7k miles p a. I have been riding a Schwinn Fastback Pro alloy /carbon for 10 years and it is still going strong. I believe that this Taiwanese frame was also sold under the Planet X brand name ? Anyway I’ve just built up a new bike using a PX RT58 carbon frame (Incidentally IMO you’re not a real cyclist until you can build and repair your own kit)-It has full ultegra 10s and Kysirium Elite wheels and it weighs in at 7.45 kg or 16lbs 7oz.
    I have so far test ridden this bike about 175miles and every thing is now bedded in and adjusted to my liking. To put it bluntly this bike is pure joy to ride. It handles superbly. It is very stiff yet comfortable and it handles like a dream and it is a real looker. Oh! And it goes like s..t off a shovel ! ! ! The first main test will be Tour de Yorkshire Sportive on May 3rd but there again it might not last that long according to some of the dome and gloom old fishwives that inhabit this blog !

    The Ultegra version was the first of the RT58s in their Sale. They did 100 of em and then switched to the Rival version. I guess it was based on what they had lots of in stock.

    A mate of mine passed on the Ultegra one and then went for the Rival one as a) he wanted 34-32 gearing for the Alps and b) he prefers DoubleTap.

    You do know you’re just encouraging me to buy a new bike? Those Ti frames are looking more and more attractive with every post you guys write.

    To provide balance, I’ve seen a Litespeed Ti frame crack too.

    Dude who broke his last week is hardly what you’d call large. I don’t hate carbon, I have two carbon, one alu and one steel bike, all have their merits. I’ve just seen Planet X frames fail far too many times to go anywhere near them.

    I’m sure my clubfeet would be happy for me to stick the pic up of his, depending what he gets back from them now it’s gone back for inspection.

    Maybe a bit left field but how about:
    http://www.planetx.co.uk/i/q/ZXMAYPXRT58C/planet-x-rt-58-carbon-road-frameset-pick-n-mix-bundle. £339.99 until midnight tonight.
    http://www.cycledivision.co.uk/product-info.php?Cero_AR24_Alloy_Clincher_Wheelset-pid363.html. £175 wheels as already suggested. And seem to come with free tyres.
    http://www.ribblecycles.co.uk/gsd/road-track-bike/shimano-105-5800-black-11-spd-double-groupset?part=GSSHIM105B580010D&sub=conf_GS_SHR&bike=1. £298.95.
    That’s £813.94 for a full carbon 105 11 speed setup with a decent pair of wheels. And you get to make the bike yourself which can only be a good thing.

    Just a thought.

    Hi Alex, rival is easily
    Hi Alex, rival is easily better than 105 imo!

    The only bike ove built from scratch is a Force 22 build and it was surprisingly easy to work on. Not sure about Shimano cranks but I’ve found SRAM easy to service. I don’t think either are better or worse for servicing!

    Enjoy whatever you get. 🙂

    Thanks everyone for your
    Thanks everyone for your comments. I really appreciate you’re taking the time to post and advise me.

    I feared it’d be a can of worms and, inevitably, it is. The comments on carbons snapping got me a little worried. I know I have nowhere near the power of a keen club cyclist (I wish!) but, as I said, I am heavier than most and certainly keen to come home in one piece after a Sunday ride.

    Other than safety considerations, from your comments I see there’s not a huge amount of difference between a good Al frame and a cheapish Carbon like an rt58, so I should probably consider the wheels and groupset more than I did so far. On this basis perhaps the Tiagra should be out and I should either get the RT58 Rival or look elsewhere.

    I’ve taken a look at Nixster’s suggestion (thanks!) and Winstanley do have Merida Scultura Carbon Comp 904 2014 Bike at £799 which seems OK and it gets decent reviews
    http://road.cc/content/review/67273-merida-scultura-comp-904
    or the quoted Alloy at £635.

    I read that the Rival is probably better than the 105. But if I should worry about safety of the frameset and the Merida gets better word in the street I should probably either go for that or consider a high-end Al alloy.

    In my decision I am keen to 1) just get one and get on with it – anyone of these will be a huge step from my current bike! 2) get something I can learn to service as I like learning and fiddling around (maybe the 105 is better for me in this respect?); 3) be a little mindful of comfort (I am not in my twenties any more and I am no longer made of muscle only – not that I ever was).

    Chasseur Patate, how did you get it with the Ultegra at that price? Do PX change their prices often or did you get a discount with a club?

    Thanks for any further comments!

    I know you are asking for
    I know you are asking for advice specifically about Planet X bikes but my £800 would be going elsewhere.
    My £800 would be going to Winstanleys as they have a Merida Scultura Alloy 904 2014 bike at £635, especially as it is in my size M/L 54 (more like a 56 in trek or specialized) and a set of better wheels (something like Cero A24 – approx 1550gsm at 175 from Cycle Division). If you really want carbon they have the equivalent carbon bike with a big discount in loads of sizes at £799. Not quite full 10 speed 105 but v.good for the money. Personally I had a Scultura Alloy a few years back, frame stiff enough not too flex but not shake out your fillings, full carbon fork, brilliant bike. (I am a similar weight to you as well)

    I believe the OP asked about
    I believe the OP asked about Shimano versus SRAM in the original post?

    I’ve had Tiagra – it ain’t pretty but it works.

    But more to the point the SRAM bike is GREEN – it’s a well known fact that green bikes are bad luck and if you buy it horrible things will happen. So don’t get it.

    Which is about as based in evidence and logic as all the ‘carbon bad alu good/alu bad carbon good’ comments you’re going to get on here. 😀
