The Helium X provides pro-riders with all the performance they need but is also an exceptional option for the aspiring road cyclist who has their eyes on the podium. Ideally suited to any rider who wants to achieve more from their performance output, wants a climb with greater efficiency, sprint with outstanding efficiency and soar past the race-pack with style.
It has a Shimano Ultegra 11 speed drivetrain within its arsenal, so it cranks up the power with efficiency and shifts through the gears with precision. Plus, it rolls on the superb Forza RC23 race wheels and Vittoria Zaffiro Pro tyres that offer fast-rolling performance and exceptional grip in all weather conditions.

Getting the Right Fit

Another reason you can have complete confidence when buying a bike from Wiggle!
If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
