    • Excellent Road Bike

      17/06/2018
      Kohi (United Kingdom)
      Used for 2 to 8 weeks
      This is my first road bike and it is great. I purchased a M frame size and I am 5'11 with a 31 inseam. If you are like: 5'10, 6ft, 6'1 or 6'2 with a 31 inseam, this should still be the correct size. A size down can be adjusted but if you purchase a size up then it can be uncomfortable, with minimal to no adjustments possible, so just wait and buy the correct size and if you're really unsure then go to halfords or a local bike shop to get measured or a Decathlon store.

      Once the bike arrived I put it together, most the bike is already fitted just few things like lights and handlebars needed fitting which is easily done as they provide all the tools. I adjusted the saddle height and distance forward and it fits me well. I can hop on easy, hop off easy and I have rode for over 2 hours with a few stops but have not felt uncomfortable.

      On delivery, the bike itself was fine, however 1 of the wheel lights were broken and I was missing 1 allen key tool but I had a spare. The box doesn't feel the most secure but it actually does hold the bike well but it looked like a used box, and finally I did not receive the cardboard bike stand which if you check their btwin bike video, the guy has it come with his bike. Delivery was a bit slow like waited more than a week. I'm assuming it was out of stock and I'm not surprised.

      The brakes. They're good don't get me wrong, however for some people it "may" be better if changed. The stopping needs more pressure on the levers to feel like the breaks are doing their job and to feel the resistance, but they work fine. It wasn't a big issue for me, but if you don't like applying a bit more pressure to feel the stopping force then upgrade the brakes. I'm gonna wait until they have worn out though before changing. Triple chainring crankset is not for everyone.

      The bike is comfortable, easy gear changing, corners well. It was this or the giant contend 2, and I know I chose correctly as a first bike.


      Some Notes:

      1. The bike wheels have a Presta Valve not Schrader so make sure you get the correct bike pump.
      2. If it is your first bike/roadbike then make sure you register your bike with decathlon and bikeregister.com - you may not know that you can register. Bike thieves love road bikes more than others.
      3. You should watch GCN on youtube for general great bike advice.

      Finally, I had not rode a bike in like a decade and I almost had to relearn, but after 2 days I'm pretty good at riding this. The actual control of the bike seems more sensitive than a standard bike, I think the word is, "nimble", but it is so much fun when you are use to it; especially on fast descents. I purchased the bike to add cycling to my workout routine, to help me lose just under 50lbs left. Already lost 70 since November 2017. Diet is key.

      I hope this review has helped someone in even the slightest way, that is why I wrote it, to assist someone as I was struggling to make a decision too.

      Thanks for reading!

      This is my first road bike and is a a good introduction model if you've never had one before. Had a few issues with the gears change, partly due to my lack of knowledge about how the gears work. Took it back in a couple of times and the staff at Southampton Decathlon have been really helpful and sorted it out within 5 minutes.

      Recently purchased and a worthy upgrade from a hybrid cycle.
      It feels very nippy and I love the sound that it makes when travelling at speed. The carbon forks smooth out the dodgy road surfaces around the North Downs and it’s a joy to ride.
      I’m still learning to use the ‘drops’ and Sora set but this will come with practice.
      Highly recommended and lives up to the expert reviews!

      this is truly an amazing and fun bike to ride. I shopped long and hard for a new racing bike with sora gears and a light frame. i kept coming back to this bike and i am certainly not disappointed. I am no racing fanatic but i just enjoy the thrill of riding and this bike ticks all my boxes. 27 gears, carbon folks which make riding on rough roads a pleasurable experience - and no road vibration or buzz to boot! i paid £500 for a medium (being approx 174 cm tall) and is spot on and fits me perfectly. I have only completed about 100 miles on this bike but its got so much going for it and i would ride it daily if time allowed. Its great for commuting and my 16 miles ride into work is a pleasurable experience. Im no light rider but this bike flies up the tricky hills with little effort and i can say with complete honesty that it beats bikes ive ridden costing £200 more!! Its even come down to £450 now so seriously grab one and you wont be disappointed.
      I bought mine from the Brent Cross store and the staff were so helpful and supportive to me. The manager was extremely helpful in assisting me and also the bike technician Andrea and his colleague who could not do enough to assist me with making sure i was happy with the bike, even fitting a rack for me and ensuring the bike was fit for MY specific needs. Thank you so much. I will definitely be shopping in Decathlon Brent Cross again soon - great brand and excellent quality products.

      Hi. I am just shy of 6'2" tall. Would a large or Xl frame suit me best? Reason I ask is because there are varying size guides on website. For example at the top of this page it says Large, but according to here, http://blog.decathlon.co.uk/sports/btwin-road-bike-size-guide/, it should be Xl.
      Also, https://www.decathlon.ie/size-guide.
      Thanks
