Description

Hand welded triple butted, gusset reinforced steel main tubes with custom tapered, curved and plated back end for a trail smoothing character with bombproof strength. Balanced 29er handling in four sizes. Stable and confident without being crazy stretched and slack. You want Hello Dave for that.

Threaded BB shell, big clearance chain stay plate Boost bolt through axle and replaceable gear hanger for crash/transport survival. External cable routing for the smooth, simple operation. Stealth dropper post routing and rear rack mounts for enduro or exploro. Lacquered raw finish for naked build detail appreciation (with eventual cosmetic rat bike rust) or genuinely dayglo paint for ultimate pop. Custom upgrades let you build your ultimate trail best friend for a crazy low cost.

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 Eagle is SRAMs' entry level Eagle groupset. Positive, 12 speed sequential shifting up to a 50 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.

29er wheels roll smoother and faster however rough it gets. Tough, wide tubeless ready Alex rims for extra grip and support Hand finished 32 spoke build for durable strength and sweet ride feel. Quality sealed bearing Boost axle disc hubs. Panaracer FireSport 29 x 2.35in tyres are a classic all rounder tread for UK riding.

Pedals not included? Why not?

Pedal choice is a personal thing. Most higher end bikes are expected to be ridden with clipless pedals. These are matched to cleats on the underside of your cycling shoes. There are a few standards of these, and most cyclists tend to stick with one standard across all their bikes. So, you don't need to buy multiple pairs of shoes! Thats why Planet X don't sell bikes with pedals included. If you wish to add pedals to your order, simply select an option from the drop-down menu.

NOTE: Please make sure you check the size guide to order the correct size of this frame.

This bike is a joy to ride. Despite being heavier than my 26" Inbred it climbs and cruises quicker as well as being far more stable on technical descents. Very clever geometry and quality components for the price make this happen. Superb!

Hi Brought this bike and due to the present Covid 19 had to wait for the delivery slightly longer than usual. Believe me it was well worth the wait, due to work commitments and being away from home for 6 weeks after arrival of the bike got my first ride today. I already have three other Steel bikes so know how smooth Steel bikes ride,, the ride on this bike is superb and my quick ride turned in to a 74 km ride which for me is a reasonable ride. It was just so good I did not want to stop, the ride was a mixture of paved and unpaved surfaces no real big hills here but plenty of off road riding on farm tracks and the like. The bike was straight out the box as specified by Planet x with the only change to there standard built was a shorter stem as am planning to fit a riser bar. The bike build is superb, the ride quality superb and the gears super smooth. Well done Plantx your whole package from ordering, delivery, design and build deserves to be awarded 5 out of 5 Stars. If anyone is looking at this bike, buy it the price is also incredibly good for this quality of bike. Well done Plant x team.

Sizing Guide
Rider Height Suggested Frame Size

5′7″ to 5′10″ Medium
5′10″ to 6′1″ Large
6′1″ to 6′3″ X-Large
Sizing Notes
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.
