FTOOBZ29
Introducing On-One's Bootzipper Frameset. Rigid only 29in mountainbike. New age fun with a vintage feel, with the On-One Bootzipper 29 frame and fork package.
Full description and spec
Remember when mountain bikes were mountain bikes? Without all this crazy suspension? When the summer was endless and we used bricks and planks for ramps and jumpers for goalposts?
Maybe you're not as old as us. Or maybe you are.
The first ever mountainbikes were fully rigid, and On-One wanted to return to that with the Bootzippers! Not just a very long rigid fork in a hardtail bike - but a proper rigid only bike. So that's what On-One did.
It's not all backward - triple and double butted 4130 tubing, hand TIG welded into a contemporary chassis, with routing for 1x drivetrain and stealth dropper post.
The 44mm headtube takes tapered forks and keeps things tidy and easily upgradeable. A threaded BSA bottom bracket shell means no creaks or weird workshop confusion. A 12mm though axle rear dropout sits at Boost 148 spacing to get the best tyre clearance and wheel strength and stay bang up to date.
A tough chainstay plate means great tyre and chainring clearance and extra durability too.
Gussetted top and down tubes keep the front of the frame strong, and let us use optimised main tubes for better handling.
The Bootzipper29 comes in four sizes with contemporary reach dimensions for riders looking for that long, low feel with a short stem. It's set to be a classic.
Paint finish includes a Phosphate and Laquer version. If you're disturbed by less than perfect finishes, it's best you avoid this.
Notes:-
| Rider Height | Suggested Frame Size |
|---|---|
| 5′4″ to 5′7″ | Small |
| 5′7″ to 5′10″ | Medium |
| 5′10″ to 6′1″ | Large |
| 6′1″ to 6′3″ | X-Large |
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.
