Park Tool HTR1 - Head Tube Reaming and Facing Set
  • £509.99

The Park Tool HTR1 Head Tube Reaming and Facing Set allows for proper frame preparation. The HTR1 combines reaming and facing of the head tube to create a perfect fit for most sizes of head cups. The HTR1 comes complete with a 30.0mm reamer, and four different size pilots, (29.8mm, 30.0mm, 33.8mm, and 36.8mm). There are cases when a reamer is required to clean out or increase the diameter of the head tube. Most times however, facing of the head tube for good cup fit is the objective. In this case, reaming is not necessary and the pilots can be used in place of the reamers to keep the tool straight and create a faced head tube. The unique part of the HTR1 is the quick-release, quick adjust feature. The bottom portion can slide off and on easily without the long threading process. This portion of the tool can still be fine tuned while in use. The tapered centering cone unit rides on a bearing for extra smooth operation. All cutting surfaces are top quality and extra sharp.

Giro Aerohead Helmet (MIPS) Helmets
  • £289.99

This Aerohead™ MIPS cycling helmet takes the same wind-cheating silhouette as the leading-edge Aerohead Ultimate but adds increased ventilation to keep triathletes and time trialists cool when the competition is hot. By using a polycarbonate shell, Wind Tunnel™ ventilation and internal channelling, this helmet is proven to boost cooling power while remaining aerodynamic. Additionally, Aerohead™ MIPS features a wrap-around eye shield that offers an impressive field of view with the convenience of a magnetic anchor attachment to allow easy storage of the lens in the “flipped up” position – Perfect for fast swim-to-bike transitions. MIPS (Multi-directional Impact Protection System)  The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head. Shop All MIPS Helmets Click Here Lens by Zeiss® Optics shield with magnetic attachment the wrap-around eye shield offers an unblocked field of view with a huge aerodynamic benefit and the shield is made by ZEISS® Optics for unrivalled clarity. A magnetic anchor attachment keeps the shield secure, yet easy to remove, and it can be stored in the “flipped up” position. In-Mould Construction In-mould construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mould helmets can be lighter and cooler than traditional helmets. Roc Loc® Air Fit System This revolutionary fit system improves helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channelling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc® 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand. Super Fit™ Engineering Proprietary Super Fit™ sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet moulds in up to 4 adult sizes to match the human body’s form, Super Fit™ sizes comfortably and securely to fit riders and feel like they are custom made just for you.
