New OS20 bikes show up at Grands

The USA BMX Grand Nationals, touted as “The Greatest Race on Earth” was, as all you racer-types know, held this past weekend.

Not only does it feature some of the most exciting racing you’re going to see anywhere, it also serves as a showcase for companies to debut some of their new products.

This year’s Grands was no different.

One company’s product in particular, generated quick a bit of buzz over the past few days. That product was Yess BMX’s 2018 concept prototype bike called Project2024.

The bike uses a frame that can accommodate two different wheel setups: OS20 and 24′ cruiser. When the OS20 wheels are used, it features a bottom bracket height of 11.5″; when the 24″ cruiser wheels are used, it sports a 11.75″ bottom bracket height.

How does this BMX wizardry work you ask?

The frame uses purpose-designed dropouts, that can be flipped upside down…changing the radius distance from axle to ground. This provides a similar bottom bracket height to be achieved despite using two different wheel size setups. 

 

The benefit?

This innovative setup could allow you to take one bike (with an extra wheel set) vs. two bikes when traveling to big races.

The downside, of course, is having to swap out the dropouts and wheels between motos….and having the time to do so. Probably a non-starter at smaller state or national races but perhaps do-able at the big UCI race extravaganzas.

Gotta respect those Yess folks for pushing the envelope on BMX innovation.

Still on the Grands/OS20 front, SSquared Bicycles also had something up their sleeves.

The SSquared tent showcased the debut of the SSquared Bicycles OS20 frame and  Answer BMX disk brake set up.

Word on the street is that the OS20 frames might be “made to order” for the time being since they still so new.

I would suggest confirming with SSquared to be sure (before you order) but…hot damn!…if true, this is a great opportunity to get a custom OS20 bike built with the race-tested quality SSquared is known for. Definitely don’t sleep on this if you are in the market.

Some pretty cool new offerings from Yess and SSquared.

It seems that the OS20 momentum that’s happening in the race world continues to grow. It’s good to see.

TNT adds some color to OS20 wheels

Tired of the limited color choices in OS20 wheels?

TNT Bicycles may just have the solution to what ails you.

TNT has done a small run of OS20* rims in multiple colors (see below) to add a little flair to your OS20 ride.

They clock in at 435 grams (per rim) and retail for $49.95 (US) per rim.

I’m kinda partial to that gold anno myself.

Hit up TNT Bicycles for all the particulars…and maybe do it soon?

Remember the “small run” part above…

 

*Or 451mm for you metric types.

Prototype OS20 Alpha is trick

Spotted this one in the Jan/Feb. issue of Pull Magazine: Michael Von Sothen’s custom OS20 Alpha prototype.

This rig is tricked out.

Check out this spec list (in addition to the OS20 wheels), it features:

  • Hydraulic disc brakes
  • Gates belt drive (with a custom split dropout)
  • 20 mm axles
  • One-piece CNC’ed BB junction
  • 3-D headtube.

That’s a lot of stuff going on here.

Wow.

OS20 overload from Standard

Oh man.

Just caught this on the socials today…Standard is busting out a rainbow of purty trans colored OS20 frames!

Trans gold, blue, red and green…Wow!

Here’s a better shot of the frames:

I would have a seriously hard time choosing a color from this lineup…they all look that good!

And if color ain’t your thing….clear over raw is pretty dialed too!

Hot damn, Standard’s OS20 game is tight!

OS20 tires mounted on 22″ rims

Ever since Chris Moeller dropped word (in July of last year) that a 22″X1.95 tire from S&M was in the works, I’ve been waiting in eager anticipation for it to drop.

Well, it’s been more than a year and we’re still waiting.

No doubt when these hit the market they’ll be a hot item for riders wanting a slimmer tire for racing, lower rotational weight or smaller size (if only to slip under the wheel height race rules).

But in the meantime…you could follow the lead of Rickard at ORP BMX.

He’s experimenting with mounting OS20 tires onto 22″Revenge rims.

According to ORP, “ it’s hard, real hard” to mount OS20 tires on the Revenge rims.

But as you can see from the pictures, definitely do-able.

Wonder how many racers are going to try out this mod…

Upsizing a 20-inch Haro XL to OS20

Jack Hoobler got a hold of us recently to tell us about his Haro OS20 that was built up for him by Marysville Bike Shop in Washington state.

According to Jack, the shop is pushing 22 and OS20 wheels in a a big way, even going so far as keeping a large stock of OS20 rims and tires on hand in-store.

What’s interesting about his setup is that Jack’s Haro is actually a 20″ Pro XL with OS20 wheels added to it.

The impetus for the “upgrade” was Jack complaining to the folks at the shop about how hard it was to go from his Downhill bike to his 20″.

They suggested that he try out the Doublecross they had built up with OS20 wheels.

However, instead of hopping on the Doublecross, he decided to borrow the wheels and have them installed on his Haro.

The result?

He was skeptical at first about the bottom bracket being too high, but he says the bike now feels perfect. Everything lined up well…including the brakes! He was even able to keep the rear wheel slammed.

Looks like an awesome setup.

Apparently the Marysville Bike Shop has a couple more OS20 builds/experiments underway as well.

Looking forward to checking them in the (hopefully) near future!

Curtis Bikes debuts new OS20

The OS20 wheel size had sort of a small uptake since its introduction (about 4 years ago) but it seems like it’s finally start to make its presence felt.

In many cases, it’s the smaller manufacturers (with the exception of GT bikes) that seemed to have embraced it earlier.

In keeping with that trend, UK-based Curtis Bikes*(known for their handmade, made-to-order bikes) recently dropped pics of an OS20 bike they put together for a customer in Australia.

*You might have also seen the Curtis Bikes’ unconventional cruiser post over on our brother site, Cruiser Revolution.

How do the numbers stack up?

Have a look:

  • Head Tube: 74 degrees
  • Top tube:21.75″ top tube
  • Chain stay: 14.7 – 15.2″
  • Bottom Bracket: 11.5″

Weight-wise, the frame comes in at a respectable 4.08 lbs.

All in all, a sweet little ride from the folks at Curtis Bikes.

Hopefully the proud new owner will share a few pics of it in action too.*

(I’m totally sweating that padset too…gives the bike that perfect old school/mid school vibe.)
