Fenwicks Wet Weather Chain Lube - 100ml}
  • £8.49

Fenwicks Wet Weather Chain LubeThis Chain Lube from Fenwicks is the wet weather version and has been improved after feedback from riders praising its exceptional performance during wet weather cycling. These improvements push the technological boundaries so that this highly tenacious chain lube can perform even better in wet-weather as well as provide longevity and a gunk free operation.It consists of a synthetic blend with excellent ester and high polymer content as well as additives to considerably boost lubricity and film potency with good adhesiveness to reduce corrosion. Synthetic oils are far more superior to mineral oils in reducing corrosion, friction, wear and longevity, due to the capability of completely blending to bespoke formulas, producing the required mechanical and chemical properties.For bikes, wet weather lubes provide more protection as operating temperatures needed for solid particles in dry lubes are seldom reached to preserve their mobility. So once dry particles have been pushed away from touching surfaces, they don't return.Features:Reduced environmental contamination means cleaner operationIncreased maintenance periodsDecreased wearIncreased protection against corrosionSmoother, quieter functioning bikePenetrates and protectsFor smooth running chainEasy clean formulaBuy Fenwicks Workshop from Chain Reaction Cycles, the World's Largest Online Bike Store.

Michelin A3 Protek Max Road Bike Tube How many road bike or mountain bike rides have been ruined by a flat? Regardless of whether it's a puncture or a pinched flat, the cyclist's hopes for the day's outing are dashed. Repairing or changing an inner tube is never easy, even for an experienced rider.Many users have lost their patience given the many steps involved in repairing a flat tire. As a result, the inner tube has become the Achilles' heel of cycling… or at least it was until Michelin's advanced research programs decided to tackle the problem. With the launch of the new Protek Max inner tube, Michelin has found an efficient, speedy, groundbreaking solution. Flat tires and all the unpleasant aspects of changing an inner tube are now part of the past. The Protek Max delivers in three key areas: it is highly resistant, easy to mount and maintains tire pressure longer.The Protek Max is virtually airtight. While a traditional inner tube like the Michelin Air Stop needs to be re-inflated at regular intervals, the new Michelin Protek Max requires inflation only half as often.The problem of twisting - so common with traditional tubes - has been effectively eliminated. In addition to being an innovative product that saves time and energy, the Protek Max is also an attractive example of contemporary design thanks to its square shape. Thus for the first time, an inner tube combines advanced technology and an equally innovative aesthetic appeal.Buy Michelin Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
