Specially designed to work with the tight tolerances and narrow profiles of 10- and 11-speed chains, but also works on all other derailleur chains, including the Shimano CN-9000. Includes removable peening anvil for securing Campag 11-speed chains.
Re-developed to reflect the advancements in red LED technology since its initial release in 2010. The LEDs have been upgraded to Osram’s high efficiency Oslon LEDs, as used in the rear light modules at the high performance end of the automotive industry.
"Pros Great construction, looks fantastic. Without doubt the brightest rear light you can buy! Easy to fit and use.
Cons Could not fit clamp on a slightly sloping road bike seat post without feeling clamp slightly brushing inner thighs. Rear light has stopped working after 18 months regular commuting use. No signs of water contamination, battery fine."
"Any body who owns a carbon frame needs this bit of kit. Well made easy to use comes in its own case, good value for money. Only loses a star due calibration window which you have to hold up to eye level to make sure you set the required torque setting. After saying that I don't think you find a better value torque wrench for the price."
