  • RRP £14.99

Spank Spoon Grom Kids Bike GripsOffering the same trail-ready performance as Spank’s adult-sized models, the Spoon Grom Kids Bike Grips are the ideal upgrade for younger trail shredders to stay in control on challenging terrains. Specially sized for smaller hands, their diamond-patterned tacky rubber compound helps future mountain bike (MTB) stars to maintain their hand position as they develop their skills.One of the most common complaints of young riders is that adult grips position their hands too far from the controls, making them move their hands around while riding or risk pinching fingers in brakes. The new Spoon Grom grips alleviate this issue, putting their hands in the right place every time, and allowing them to set up their handlebar controls to achieve the most comfortable grip when cycling.Features: Material: Tacky Rubber grip area, alloy clamp rings Length: 100mm Diameter: 30mm Single or Pair: Pair Bar End Plugs Included: Yes Use: Mountain Bike (MTB) Tailored to fit children's hands Micro-diamond grip pattern Weight: 95g (Pair)Buy Spank Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
