    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!

    I have had mine for a while
    I have had mine for a while now and have covered a couple of thousand miles on it in the last 6 months ish. It is still solid despite being caught out by a pot hole or 2. I have even ridden through winter on this and it is still going strong.
    One thing that has happened I am not too happy about is the plastic guides that go through the frame have somehow stuck in the frame. Where the cables enter the frame there appears to be some galvanisation ( presumably the reason for the guides seizing )
    Still like the frame and the way it rides, its light at 7kg for the xs frame with campag build. Great at climbing and comfy.
    Prices have come down now so an even better deal now. Bit of good and bad, for this price it will have compromises but still love mine.

    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 !

    Two weeks to go to TdY Sportive and the RT 58 is still in one piece and riding like a dream . Only 600 hard hilly Lake District miles on it though, I suppose there’s plenty of time for some serious spontaneous combustion yet so I have the old Schwinn Fastback Pro lubed and pumped just in case!

    Nah, I’d just not bother putting too many watts down.

    FWIW I ride a PX RT 58 with SRAM Rival. It’s my first carbon frame, I have ridden steel prior to this. I am tall and relatively heavy 1.93m and 95kg. I chose it because it looked to me like a great balance of spec, price and looks. It’s all personal really.

    If it makes the OP any happier, I bought mine last autumn, so I also missed out on the recent bargain prices. On the plus side, I have been able to enjoy what I think is a great bike. My second outing was the South Downs 100 last October, I had a great time, the wifli gearing was just what I needed to get over Butser after 80 miles.

    So far it has not spontaneously collapsed, despite being ridden reasonably hard over some terrible roads in the Surrey Hills. One of my other bikes is a carbon framed Giant Cadex MTB, still going strong after more than 20 years. I think that the frame is the only original part of the bike, everything else has been replaced after being worn out. 🙂

    What PX frames are they with
    What PX frames are they with the chain stays bust And are they all the same type?

    I don’t have one myself, but I know of many people who have PX carbon, road,track and TT frames, even some old ones, I don’t know any that have broke them.

    I suppose though if the warranty pays out as claimed above (although there is also good feedback out there) then it does warrant some consideration.

    Lots of brands do lifetime frame warranties, but you pay for that.

    As I said, that’s one of three PX frames I’ve seen go crunch and none of them through impact. Regardless of frame PX told him them they wouldn’t replace them or simply offered 10% off the cost of a new one, so the gash product + customer service is relevant and people might like to know.

    I’m on three Px frames now and they’re possibly the most popular bike for triathlons.

    They’re cheap cos they haven’t the overheads of the bigger brands and sell direct through their shops. They aren’t going to take short cuts.

    Happy to oblige.

    Thanks everyone for your
    Thanks everyone for your advice. I read everyone comments several times before looking around a little bit more before deciding to get the SRAM version of the PX58 a couple of weeks ago.

    Unfortunately in the meantime the bike had gone up in price. I contacted PlanetX who told me they cannot bring back the price. What a shame – lesson learnt. I then decided to switch to the sculptura carbon but that’s also gone up by 100pounds. The PX58 tiagra is still available but I’ve decided I’d get a 105 or above; or switch to an alloy frame.

    I just wasn’t aware PX would move the prices around so much in a matter of days. So here I am with no bike with a glorious weather out. Silly me; lesson learnt. I’ll keep looking. If you’re back from your ride and want to offer further input, please feel free to. It’s much appreciated.

    Oh last thing, I’d absolutely love to be building the bike. The prices for the components mentioned by davieke are still available. I’ve changed several things on my own bike over the years. However, doing a whole bike, I fear I may be pushing my abilities a little too much and with little time in my hands I’d rather not do it. Next bike!
