  • 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.

    Koo Open Eyewear Black/Red Description

  • Brand : Koo
  • Season :
  • Code : CEY0002.226
  • Weight : 0KG
  • Koo Open Eyewear is specifically designed to work seamlessly with Kask cycling helmets. Available in different colours and mirroring the sharp aesthetics of the Kask helmet range, no combination of glasses and helmet will look better. The arms of the frame sit perfectly in the air vents of the Protone and Mojito, so they can be safely stowed when not being worn.

    Even if you don't own a Kask helmet, Koo Open Eyewear is an excellent choice. Clever design features help to set them apart from the rest in the saturated cycling glasses market. The sunglasses are constructed of polycarbonate, with each component 100% made in Italy. The arms of the frame rotate around pivots, meaning the angle of the lenses can be changed whilst you're wearing them. Koo describe this as their “Airflow Active System”, it gives you control over where you'd like a cooling airflow, whilst also allowing you to pivot the lenses and look over them if you're heading into a tunnel or other dimly lit area. Another benefit of the pivots is that the Open Eyewear folds up neatly small for easy storage. Flexible temple tips and adjustable rubber noepads improve the fitting and comfort, helping the glasses remain securely on your face during a long ride.

    Koo Open glasses feature easily-removable, interchangeable lenses for year-round optimum vision. The lenses are made by internationally renowned Zeiss, for premium optical clarity and protection for your eyes. Koo Open glasses include two sets of lenses, one darker lens to match the frame and another extra clear lens. The darker lens is perfect for use in conditions from overcast to very bright, with the clear lens best for late evening and night time riding. The lenses are simply changed by moving the two retaining tabs at either side of the lens. The lenses are wide and tall for great coverage and unobstructed vision. Simply exquisite, Koo Open Eyewear cycling glasses are the perfect compliment to any Kask helmet, or any serious rider who needs crystal clear vision and protection at all times.

    Other colours available. If you wish to place a special order for these glasses in a colour not in stock on the website please contact the store.
