Bike Check: Jennie Stenerhag's Silverback Stratos SBC

Silverback's latest dual suspension cross-country race bike, the Stratos, was unveiled ahead of the 2019 Cape Epic. The Silverback - Fairtree pairing of Jennie Stenerhag and Mariske Strauss raced the Stratos in the 8-day event. Get a detailed look at Stenerhag's new Stratos race bike below.

The New Bike


As the Silverback Stratos is a brand new bike, let's jump into some of the new features it offers. The Stratos follows the Sesta in Silverback's cross-country race bike category with an updated slacker geometry to assist handling on technical terrain. The head tube angle is 69 degrees and seat tube angle 74.5 degrees with the medium frame sporting a 435 mm reach, 1136 mm wheelbase, and chainstays measuring 435 mm (across the size curve). To assist further the Stratos is designed with dropper seatpost support in mind.

Silverback built the Stratos with an asymmetrical design which is most noticeable in the front triangle. The result is a number of eye-catching flat surfaces and sharp angles forming almost triangular shaped tubes in places. According to Silverback the purpose of these shapes is to better manage riding forces through the frame at the points where they are strongest.

With the rear suspension, Silverback made an effort to make it lightweight. There is an oversized tapered pivot just above the bottom bracket that makes use of a commonly available headset sized bearing while the rocker is injection moulded carbon fibre. The suspension is assisted by slender seatstays that flex as the bike travels through the suspension eliminating the need for moving parts between the seat- and chainstays. And, as you can see, there is space to fit two water bottles in the front triangle. Although not fitted to Stenerhag's bike, a storage compartment can be fixed to the Stratos in the wedge-like gap where the top tube and down tube meet at the head tube.

Stenerhag races on Fox's range topping Factory suspension with their cross-country focussed 32 Step-Cast fork and Float shock. She has a dual remote lockout lever to open and close the fork and shock.

The drivetrain is a SRAM XX1 Eagle system featuring a 32 tooth chainring and a Stage Power left crank arm. The brakes are also from SRAM, their cross-country Level brakeset in the Ultimate specification level.

The wheelset is courtesy of the Swiss company Ceetec with their carbon rims and a set of DT Swiss hubs. Stenerhag races on Maxxis tyres electing for an Ardent Race 2.35" for the front and a Rekon Race 2.25" on the back.

Ceetec is also responsible for much of Stenerhag's cockpit, with handlebars, seatpost, bottle cages, and a custom "Jennie" top cap. The saddle is created by gebioMized, a German bike fit specialist.

That cable popping out of the top down tube? WTAF!?

 

Edit: D'oh! Wrong tube.

@Odinson, ok so i've looked and relooked at the photos - no idea what you are referring to?

Headshot, May 06 2019 02:58

I think he means the shock lock out cable...

 

I think its pretty cool looking for a marathon bike, that is :-)

DJuice, May 06 2019 02:59

The storage compartment will hide the cable if added.

What is the weight?

BikeisLife, May 06 2019 03:01

Can't wait to get mine!

It's a good looking bike, no doubt, but that lockout cable is an eye sore.

What's up with that support thing up front? No bike has a support there. Is the frame that weak that they need to put in a little brace?

Support for when you #aerotuck

Wonder what the reason is for moving away from their old Sesta suspension design, apart from the obvious space for another bottle cage. The old bike looks better in my opinion.

also very keen to hear how this has improved from the sesta, other than the double cage and storage container thingy.

 

sesta looks much better!

Fugly!

BaGearA, May 06 2019 04:52

Momsen no longer have the ugliest bike...

Headshot, May 06 2019 05:55

And now no vertical shock .... wheres the Hib vertical shock dude now?!?!?!

DieselnDust, May 06 2019 07:26

The brace is there to assist with mounting the storage box as far as I could tell very elegant solution, better than a cavity in the frame that requires an extra kilo of material to claw back strength and stiffness

Andreas Brooks, May 06 2019 07:34

Looks like every few years companies need a "new" design and changes the location of the shock.

Andreas Brooks, May 06 2019 07:35

Swat storages looks the best and is the best solution IMHO. Looks stealty and offers a ton of storage.

Me rida my bicycle, May 06 2019 09:06

I have seen the prototype frame/bike and a shop ready one to.
I like it all the angles the weird shape down tube even the brace. It's bold and something completely different and the first Silverback I actually want 😊

It's vertical if you're manualing #badass. 

koukie, May 07 2019 09:08

This is for me the best looking marathon bike at the moment. I would like to test ride one.  I like the lines a lot

A headset bearing for a pivot?

Can we just pause there for a second...

Bigger and stronger?

There's a live Tech Q&A with Silverback's product designer at 12pm today.

I like it.

 

What is with all the hate RE the top/down tube brace ... no different to what spaz do on the Enduro frames.

Jacquers, May 07 2019 10:57

I like it as well, especially the carbon look. And it looks fast!

Bwahaha. The Enduro is symetrical and looks uber cool - one of the most recognized frame features ever. This is a one sided argument, sorry.
