Casey Sussman is the man from Mars Cycles of Oakland, California, a small frame building company specializing in custom fillet brazed and lugged steel racing frames. Casey has been building for a couple of years, his bikes proven at events like the Red Hook Criterium in Brooklyn and more, and now he can add a People’s Choice award for NAHBS 2015 to his accolades…

Casey’s NAHBS cyclocross / gravel bike features a mix of fillet brazed frame tubing from Columbus and KVA; Columbus Max top tube, Columbus Life seat tube and chainstays, and KVA stainless steel down tube and fork blades.

Cables on this single chainring cyclocross / gravel bike are run internally, entering beneath the downtube and running continuously through the bottom bracket shell, exiting at the rear dropout, and mid-way along the left chainstay for the rear brake.

Rear chainstays are asymmetric, allowing room for the brake, which mounts directly through the stay, negating the need for a bridge.

Mars Cycles bikes are all custom, meaning features such as external cup headsets, press fit bottom bracket bearings and anything else desired, can be chosen by the customer.

The NAHBS bike featured additional touches like hand cut, hand perforated leather handlebar tape, topped off with a custom covered Fi’zi:k saddle.

Prices begin at $1,500 USD frame only, add $250+ for a fork.

That rear derailleur housing is in such pain. I feel sorry for it.

So that’s the second 11speed system i see with a X9 derailleur. How does this work ? It is a sram 11 speed cassette ? What cassette ? A 11-32 ? The new 11-36 ? It has standard sram road shifter ?
Please give some detail 🙂

No way that thing shifts right. 11spd cassette, x9 derailleur, and than tortured housing

Antoine and Stephen, Please count the gears, its only 10 on that cassette. Sram mountain and road 10sp systems are compatable.

Other than that its actually one of the better looknig bikes I have seen come out of this show

@Dan – that is quite clearly an 11 spd Ultegra cassette. Look at the “-gra” on the lock ring. I do remember reading somewhere (Zinn maybe) that SRAM 11 spd road shifters will work with a 10 spd mountain cassette just fine, though I’ve never tried the combo myself.

He should have used an inline barrel adjuster instead. That shifter orientation gives me vertigo.

Dan, did you even count them before writing that? There are clearly 11 gears!

I counted again 4 time, there are 11 cogs. I already read somewhere there was a kind of lucky number happening on one of those combination allowing 11 speed with X9 derialleurs but i would like more details.

looking closely cassette is an ultegra 11s 11-32.

Matt, the frame a little too early nineties for my taste. Specifically the terrible looking seat stays ala Schwinns of that time period.

Hi. I made this bike. I used 11 speed rival shifters, 11 speed ultegra cassette, and “10” speed x9 rear derailleur. It’s the same cable pull, 10,11, the derailleur doesn’t know the difference.
