Renowned for both its versatility and reliability Planet X's Uncle John is much more than the cyclocross race pedigree from where it began. Improved spec, lower price, more choice, and it's under the C2W limit- what more could you want? Well, it's now available in blue as well as red...
Uncle John is our classic cyclocross frame, updated with new 2012 revisions to keep it ahead of the crowd. Integrated headset, disc mounts, give it cutting edge performance, along with mudguard and bottle boss placement that mean it's happy on the daily commute or winter training ride.
Triple butted aluminium, developed from our award winning Superlight Team Alloy model, with the security of fatigue resisting gussets and revised internal butting profile. Uncle John - classic cyclocross from Planet X.
The SRAM Rival build makes it the perfect do-it-all, go anywhere, bike. It really is super-tough and durable enough to see you through the depths of winter. It's ideal for the commuter run, for stacking the winter miles in on the Sunday runs or for competitive use on the cyclo-cross circuit. When versatility is the issue, and value for money the key, there's nothing to beat the Uncle John SRAM Rival.
The Planet X Uncle John:
The triple butted lightweight aluminium frame can withstand the very worst of weather conditions so in a world where strength and reliability is as important as speed and comfort the Uncle John comes in to its own.
It's been designed to accommodate full mud-guards to keep everything nice and dry and can take up to 35mm tyres. The rack mounts are an added plus. It's therefore equally at home on the commuter run as it is on the trickiest of cyclo-cross circuits.
Bike Radar rated the Uncle John 4.5/5 commenting on its "Confidence-inspiring ride and spot-on handling".
SRAM Rival Double Tap Technology:
SRAM are fast becoming market leaders in bike components. We've continually impressed with SRAM kit, we're not the only ones. SRAM sponsor some of the biggest and brightest teams and athletes in the world: RadioShack, Saxo Bank, Astana, Cervelo Test Team and some of the most outstanding triathletes including Alistair Brownlee & Julie Dibens.
Rival offers top quality performance and outstanding bang for your buck. Rival utilises much of the technology that is featured on its professional level kit including the 'double-tap' shifting- offering "Exact Actuation" precision front and rear shifting with silky smooth accuracy.

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.
As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
