The Hello Dave from On-One is the sickest steel hardtail for properly insane bike park and DH action, or just bombing the maddest trails in your local woods. Premium triple butted steel frame, radically stretched, slammed and slacked out like a World Cup DH racer. Add big, sticky 29er tyres, 150mm travel RockShox Pike fork and Reverb dropper plus crazy powerful E-bike brakes and the Hello Dave will tame even the wildest rides.
62 head and 77 seat angle with slammed stance and reach up to 520mm for ultimate rad ride confidence. Premium triple butted BMX steel tubing for a totally bombproof but slam smoothing vibe. Slim, shaped rear stays so it still feels alive hustling roller coaster singletrack. Fancy machined yoke for tons of tyre space even with 29 x 2.6in rubber.
Short seat tubes mean you can size up and put your front end in a different postcode if you want. Super steep seat angle and long chainstays for winching back up the steepest slopes for another go. Boost spacing and forged and machined chainstay sections for masses of mud room even around 29x2.6in tyres.
Bolt through axle for security and replaceable gear hanger for when you bend it. External cable routing and ISCG chainguide ready BB for the smoothest operation and simplest servicing. No rack mounts because it's made for psychos not cargo. 3 colours or a lacquered raw finish for naked build detail appreciation.
RockShox Pike Select 150mm travel for confident all round control. DebonAir spring combines super supple traction with sorted big hit response. Short offset makes steering feel lighter at the bar but even more surefooted on the ground. Tough, slopestyle proven, 35mm legs keep you on line however crazy things get. Charger rebound and compression damping adjustment lets you dial in your ideal ride however big you are or big you go.
SRAM's Guide RE are designed for E-bikes but loved by every gravity maniac without money to burn. Monster Code DH brake power smoothly controlled with a lightweight Guide trail brake lever.
GX Eagle is the performance/price sweet spot in SRAMs MTB range. 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. Super broad, forged crank arms with DUB axle power up climbs and laugh off big landings.
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.

Pedals not included? Why not?
Pedal choice is 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.

| Rider Height | Suggested Frame Size |
|---|---|
| 5′3″ to 5′8″ (160cm-172cm) | Medium / 400mm |
| 5′8″ to 5′11″ (172cm-180cm) | Large / 430mm |
| 5′11″ to 6′3″ (180cm- 190cm) | X-Large /460mm |
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.

Build your bike in 3 simple steps
Blown away with how good this bike is. I went for the dark raw gloss and it is an incredibly good looking thing. This is one of the fastest bikes I have been on, amazing in corners so much g force all with a great level of compliance. (Cushcores have made hardtails great again). I have FS bikes, but I grab this all the time. It is so much fun. You get the odd KOM over time, but in the first month of riding Dave I have had 6 KOMs on this bike. I have clocked 56kms/hr on it, did I mention it is fast. Laughs at steeps. So much fun, it will push you to go harder.
