    • Great value, but...

      Elliott (United Kingdom)
      Used for 3 to 6 months
      I was really happy with this bike, I love the look of it, really decent spec for the money, a very comfortable ride, seemless shifting and really fast. However, when climbing or really putting some pressure through the peddles when sprinting, the frame flexes beyond what I would consider normal or acceptable, so much so the rear brake calipers rub the rim of the rear wheel. Initially I thought perhaps I hadn't done the QR bolt up tight enough, but after tightening it further, it was clear this wasn't the issue. I have recently called the store to ask their advice and the man simply said "it is very normal" and continued "my colleague has the same bike and he said his does the same. Just loosen the rear brake." He offered to do this for me, but surely he's missing the point. I'm no powerhouse sprinter, far from it. I am 180cm, weigh a fraction over 11 stones/70kg.

      I really do love this bike, but before purchasing (as I have), be aware there is a considerable amount of flex in the frame, more than any other I own/have ridden. Such a shame, because in every other way I am really happy with it.
      Great value, group set, wheels, seat etc...
      Just one, too much flex in the frame
    • great Bike

      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 !
