    • Outstanding Value

      So far, the 720 AF has been quick, comfortable and hasn't had so much as a squeak or rattle. The aluminium frame is attractive, comfortable and swallows up road buzz.

      Aluminium is slightly heavier than carbon but overall the difference between this and my old Planet X is negligible, the whole package feels so sorted and suited that the few hundred extra grams is barely noticeable (plus, I weight 95kg so what's 300g?). The direct-mount brakes are assured and powerful, the Mavic Cosmic Elite wheels are great all-rounders and they've converted me to 25mm (or wider) tyres from now on. Looks-wise the two-tone bars grab attention and overall it's an attractive looking bike.

      There's a little flex at the bottom bracket when really stamping on the pedals but that can be forgiven when you remember the spec and price. A £500 groupset, with £300 wheels and a £70 saddle, on a UCI-approved frame. It's a crazy price for a very capable bike.

      The only downside is I'd like to have had a choice on stem length/bar width but it's a minor gripe and one you can apply to most bike stores. I can't recommend BTwin enough, they have something for everyone, from new to old riders.
      Spec, comfort, looks.
      A choice of stem/handlebar width would be nice.

      Great value bike.
      Fantastic spec.
      Wish the gears were set up better at first.

      This is first 'proper' road bike I've owned (the previous was a £300 bike from halfords that weighed the same as an elephant) loved the smoothness of the ride and the gear . I did change the tyres for some gator skins as the Flint on the roads around me will shred anything else. Also put a fabric saddle on
      Weight, gears , appearance
      Peddles , they have to be swapped out !

      Voted best budget bike 2016 and it lives up to the review.This may be the best bike i have had yet but only done 150 miles so far.I thought the cassette at the back would not get me up the very steep hills in Cornwall but as yet no hills have beeten me so don't rush and buy a 11-32T cassette in a hurry.
      Best value bike around
      Had to have it delivered as no Decathlon store
    • Excellent bike

      Best bike for the money, I've no doubt. I tried a lot (A LOT) of bikes and settled on the ultra 720, it's very out for an alloy bike, and the ultegra group set is very desirable at this price point!

      It's only downsides were the wheels and handle bars, but that's personal preference, hopefully there's a pic in the 'customers pictures' tab showing what mine looks like now with upgraded wheels, saddle, and handlebars.

      If you buy carbon at this price point, you'll get a heavier bike, and a lower group set, the ultra 720 is worth a test ride if your looking at purchasing at around the £1k mark...
