    I wanted a road bike with flat bars, having been used to mountain bikes for years, I then bought a hybrid with suspension for lane riding which was fine, I have never been keen on a full out road bike, I decided on the Triban 520 due to the good kit, weight and good reviews,
    Delivery was very fast. The shimano Sora & attention to finishing kit and good weight are very good(like small bolts for stem to keep weight down) hubs are very smooth running,may even be cartridge bearings not loose cone & ball?? . Bike rides very well Quick and very stable and comfortable, smooth ride, sensible 28mm tyres, 11-25 cassette I struggle with on hilly back lanes where I live, this will be replaced with 12-34 which I use at moment.
    An excellent bike, very well kitted for £429, which is ideal to upgrade as bits wear out, good attention to details.(I used to run a bike shop,most brands spec cheap stuff where you cant see it, this seems not the case here) An excellent upgrade from my hybrid for longer rides, could find nothing giving as much as this for the price, and its good if not better than expected, and rides very well.
  • Great quality price

    Bought for my 14 year old son to speed up his getting about versus a pretty light but inherently slow 26er mountain bike. He didn't want the hoops of a full on road bike and the weight of most hybrids at the price point was high. Solution, the Triban flat bar. Road bike weight/speed without the hoops. Keep the 26er mountain bike for when needed. Hybrids are neither good off road or on.
  • Still hopeful.

    Tried to order this bike online unsuccessfully. Checked with Decathlon who emailed that Triban 520 flat bar was no longer available. Upon visiting Decathlon at Oxford I found this was not the case (!). My size was not in stock so placed order online using the stores own ordering system assisted by very helpful staff. Much confusion followed - too lengthy and boring to relate - avoid Decathlon's online ordering service if you can. Bike arrived - packed and prepared very differently to the website video, (ex demo?) but fine. Nice machine. The problem is the gears. Ok changing from lower to higher. Higher to lower ? the change is either delayed or doesn't happen at all. Advice please.
    I cannot recommend it as things stand.
