  • Who are we?

    A bit about us

    Flat Harry's mission is to be the best local bike shop in the Thames Valley area, our customer base is broad, attracting cyclists from all the towns and villages around Cookham; in a radius around us that passes through Lane End, High Wycombe and Beaconsfield, onto the Chalfonts, Gerrards Cross, Uxbridge, Windsor and Eton, through Taplow, Maidenhead, Bray and Holyport, and over to Marlow and Henley, our customers are happy to travel to find us, knowing we cater for every and any cyclist. We're mad about cycling and love it when anyone shares our enthusiasm, be they an aspiring fan of the sport, a tech hungry hard rider spinning their best speed machine, a thrill hungry mud lover, a hardened commuter battling the traffic, or a leisurely rider on a modest budget looking to have fun and relax on their bike.

    Whether it's serving coffee and flapjack on the mid-ride break, fixing your tusty steed, performing a bike-fitting or providing you with the right gear for your ride, we do it all and a lot more at Flat Harry's. We are proudly independent and thus only stock parts and brands that we are passionately proud of, and believe are the most suited for cyclists coping with the flint strewn roads and trails in our area.

    Our obsessive temperament, collective knowledge, engineering expertise, focus on quality and debunking of fads are what distinguish our shop, and make our customers return time and time again. Building trusting long term relationships with our customers is really important to us. Simply put, we want to be the place you trust above all others to do the right thing for you. Some folk might try and take advantage of our good nature, but we believe what goes around comes around and we want you to value our approach.

    X3 VENTO white/black Description

  • Brand : Fizik
  • Season : 2019
  • Code : VEX3OCMI12010
  • Weight : 0KG
  • new from fi'zi:k for 2019 - the Vento Overcurve X3 is an XC racing shoe designed and created to deliver its core functions: to fit precisely, protect you and transfer watts efficiently as you power through the race tape.

    The particularily stylish Microtex upper is supple yet strong and stable for a comfortable and consistent fit. It is assembled in a sleek and streamlined yet highly ergonomic pattern, offering you the protection you need.

    Overcurve is the name given to the shoe construction, featuring a staggered collar that wraps around the ankle, tracing the natural misalignment of the ankle’s two bony protrusions: the lateral and medial malleoli. The result is an asymmetrical shape, with the throat of the shoe curving over the foot from its outside to its inner side. (or as Cris simplifies ir, the ankle openings are asymetrical) The closure is simple and secure, powered by a micro-adjustable BOA IP1 dial.

    Vento Overcurve X3 are assembled with extensive use of welding and laminated reinforcements, reducing exposed stitching that could collect dirt. They are light but tough, durable and easy to wipe and clean.

    The race-orientated characteristics of these shoes are continued with the X3 carbon injected outsole: it’s minimal to save weight, but stiff for power transfer, and with an aggressive tread that claws the ground and easily sheds the mud.

    or as Cris says, "these are stylish shoes for gravel, for mountan biking, for touring, or anything where you might want to ride a bike and do a bit of walking too whilst showing you've got bit of class and style.  Mine's a pair of 44 please."
