Planet X Jack Flash SRAM SX Mountain Bike

What happens when you take the Iconic Planet X Jack Flash Frame but update it for a modern crowd? We’ve kept the things you love, the gusseted headtube junction and X stamped chain stay bridge, the clearance and low stand over height, but refined the design to make it more functional and easier to build and maintain with modern components.

With progressive geometry focused on trail riding this 130mm 29er hardtail will be able to attack any trail you throw at it. Other features include stealth dropper routing, internal cables and wide tyre clearance.

Rockshox Judy Silver TK 29″ Boost Fork for uncompromised control at an affordable price. 130mm of super smooth travel for attacking the trail without unbalancing the handling. Full size legs for accurate handling and smooth stroke however hard you ride. Adjustable DebonAir spring and Motion Control damping are easy to adjust for every ride and rider.

SX is SRAM’s entry level Eagle groupset. Positive, 12 speed sequential shifting up to a 51 tooth wall climbing winch. Clutch rear mech and X-Sync2 tech for quiet chain security however rowdy you get. Ultra durable steel chainring with DUB axle to power up climbs and laugh off big landings. SRAM Level hydraulic disc brakes for effective, lightweight all weather control.

Approx Weight: 14kg (Medium)

Pedal choice is a personal thing. Some people prefer to ride with clipless pedals matched to cleats on the underside of your cycling shoes, others may prefer a flat pedal paired with shoes with a tread designed to provide grip without the aid of cleats. At Planet X our bikes don’t come with pedals included but we do sell a wide range of clipless and flat pedals for all types of cyclists, see the following link for our range – Pedals
