Product feature
  1. Frame
    The fruit of the cumulative experience of creating ever higher performance bikes, Mach is the latest addition to the racing family. Made with Evo Power carbon fibre, it is designed for pure performance. It preserves the necessary comfort on the load-bearing upper structure, while its frontal rigidity has been lowered by 10% compared to the Facet ESR frame, improving comfort on longer rides. Carbon frame dropouts. Weight: 1150 g in size 55.
  2. Fork/suspension
    This fork has been designed to accommodate the power of a pro sprinter and the precision of a downhill racer. It has a conical pivot (1-1/8" at the top, 1-1/2" at the bottom) and 57 mm wide blades at the bottom of the pivot, giving it unrivalled rigidity. Carbon fork dropouts. The frontal rigidity has been reduced by 10% to make long-distance rides more comfortable. Weight: 320 g in size 57.
  3. Drivetrain
    11-speed Shimano 105 groupset. The 105 offers the same precise indexing as the Ultegra and Dura-Ace groupsets. The dérailleurs feature an all-new design. The front derailleur has a guide combined with a new spring mechanism that ensures smooth shifting between chainrings. The rear derailleur adopts a tried-and-tested mechanism used on the Dura-Ace groupset (cassette with 32 cogs max, for mountain climbs).
  4. Brakes
    B'Twin racing dual-pivot brake callipers for excellent precision while braking.
  5. Crankset / cassette
    Shimano compact crankset: 52 x 36. Shimano 105 SS front derailleur. Shimano 105 SS rear derailleur (32 cogs max). 11-speed Shimano 105 cassette: 11 x 28. 11/12/13/14/15/17/19/21/23/25/28.
  6. Handlebar / stem / steering
    Compact B'Twin 6061-T6 alu handlebar is scaled to the bike size. The compact shape is becoming increasingly common in the peleton, as it allows you to keep your hands low on the handlebar without being uncomfortable. Handlebar weight: 320 g in size 420 mm. The B'Twin Facet stem is made out of 6061-T6 aluminium. Scaled to the size of the bike. Weighs 140 g in size 110 mm. The steering features sealed long-life bearings.
  7. Wheels
    B'Twin Aero 20/24 wheels draw their architecture from the best product on the market. They have a versatile 24 mm high rim profile and 20 aerodynamic spokes, offering noticeable thrust when accelerating, thanks to a weight of only 1760 grammes. The spokes are mounted on to the hub in a radial pattern making it possible to increase the tension and thus increase the lateral stiffness. The hubs are mounted on cartridge bearings that are surprisingly smooth.
  8. Tyres
    Hutchinson Equinox is an excellent tyre for fast-paced training rides. Made with steel beads and bi-material rubber. The tread is harder than the sidewalls, and is mounted on to a 66 TPI carcass. Weight: 290 g.
  9. Saddle / seat post
    B'Twin Comp saddle chosen for its versatility. Weight: 320 g. The seat post is short since the frame comes with an extended saddle tube; the head and stem are made of aluminium. Weight: 200 g.
  10. Pedals
    B'Twin Comp. This clipless pedal (230 g per pair) is one of the lightest on the market. Wide body for more efficient transfer of pedalling power. No-maintenance, sealed cartridge bearings. Its shape allows easier adjustment of cleats. Cleat tension can be adjusted depending on the use: high for powerful sprinters, low for beginners. Comes with cleats.

  • Great Bike

    Pete (United Kingdom)
    Used for 2 to 8 weeks
    Love this bike. First ride was a 75 miler in the Chiltern Hills and this bike was great.
  • Simply Superb

    I started cycling just over 2 years using a BTwin 500SE and after many hundreds of miles I decided to upgrade. After much research I plumped for the 720CF. I made a superb choice. A responsive frame and excellent 105 groupset make this bike a pleasure to ride. The geometry is relaxed and a 100 mile sportive today confirmed my initial assessment.
    If you are looking for a lightweight bike (my XS weighs 8.1 kg) for sportives or a full range of training rides you simply must give the 720CF serious consideration.
    Liightweigh, comfortable geometry & superb groupse
  • Carbon, lightweight flyer

    Neil (United Kingdom)
    Used for 2 to 8 weeks
    Decided to treat to this as have a TT bike that's obviously frowned on for sportives.When walked it outside (no cleats, wrong seat height) took off up the car park and the bike is effortless to get rolling.Done few rides but all sub 40 mile so far, however looking to sportive it this/next month at distance not yet ridden it has inspired that confidence.
    Weight, agility, comfort
    cannot adjust seat as its so tightly locked.Why?
  • A phenomenal road bike

    Martyn (United Kingdom)
    Used for 2 to 8 weeks
    As a cyclist with over five decades of experience this is my first full carbon road bike (and my third B'Twin).

    This is a truly phenomenal road bike and worth every penny. It is very taut and responsive and, (with a Spa Aire racing saddle) extremely comfortable over distance.

    Gear changes are, as you would expect from Shimano 105, extremely precise. The B'Twin brakes are phenomenal and stopping is fast and predictable.

    I changed the tyres for Schwalbe Durano Plus because I prefer tyres that are unlikely to puncture (as I cannot walk any distance due to disability).

    I'm unable to fit SKS RaceBlades to the front fork because of the angles on the fork but I am more likely to use my Ridgeback Panorama Deluxe as a Winter bike.

    The gearing is such that I can get up any hill using the big crank and fitted cassette and only need to drop onto the smaller crank if I need a "Granny" gear. I imagine that when my current cassette needs replacing I may go for one with a wider range (say 11-32 or 11-36 if I can get one) and I'll never need to change gear on the front end again.

    The riding position is more aggressive than my touring bike, as expected, but I love it to bits - especially hurtling down hills. Overall I cannot fault this bike and, yet again, I am so glad that I bought a B'Twin.
    Everything (though I chose to change the saddle)
    Nothing at all.
  • mack 720

    Mark (United Kingdom)
    Used for 7 to 12 months
    I have hired expensive big brand names on holidays and couldn't understand what all the fuss was about . So when my old alloy bike died I turned to the experts in magazines to get some information on the best value carbon on the market. Any review on this product has been very good . The bike is very eye catching with the odd angles in the frame it makes it look a bit special. It is a lot faster than any bike I have been on before and is a very good fit for me. I have been on it now for half a year and lost count of the miles ,even had a few race events on it . After all the miles I have had no mechanical problems as the build quality is very high. Just bye it its great
    great price
