2017 Philly Bike Expo: Mars Cycles JRA Approved Track Bike – Jarrod Bunk

2017 Philly Bike Expo: Mars Cycles JRA Approved Track Bike
Words and photos by Jarrod Bunk

David from the Bay Area contacted Casey Sussman over at Mars Cycles (Featured here during NAHBS) for this rad track bike!  Built for everyday commuting, from Columbus Zona double OS tubing, and featuring a wrap-around seat stay cluster that morphs into the ISP with a Ritchey topper, this bike is far from ordinary.

The Deluxe 840mm Ti bar stem combo along with 45mm deep carbon Deluxe wheels should make for some fun rips through traffic on this JRA approved track bike. Other details include an ENVE fork and a Columbus tapered headtube with raw, un-filed fillet construction throughout.  I’m so stoked on the stance of this bike.

    Damn this thing is rowdy! Details on the integrated bar/stem?

  • nothingfuture

    I love the whole thing, but:

    That stem/bar combo in Ti is PURE SEX.

  • Done right.

  • Willy Don Gouda

    JRA approved, dont give a fuck!

    Thing is mint. A very well thought out and put-together package. Just ride it!

  • Jack

    This is prettier than any bike I’ve seen on any site so far. Well done Mars cycles.

    You know you’ve got close to enough bikes when this is your everyday commuter

  • I’m not much of a track bike person, but what I love about this frame is that it shows that steel can be done in a modern, even minimalist way. For those who don’t like the old fancy lugged look, this frame is fantastic, while still being clearly a steel frame. Where as a lot of modern completely smooth fillet brazed frames somehow lose the steel look. (Personal opinion here, obviously) I’m not so sold on that one piece stem/bar though. It’s neat, but I guess it is a love it or hate it look. It’s the details though. All the little details in this frame that make it special.

    Shameful to have the dropouts painted over like that. Drilled fork crown, do you even track?

    Otherwise, gorgeous.

      “Built for everyday commuting…” Do you even read? LOL (had to mess with you)
      If dropouts are not stainless, they need to be painted to protect them from corrosion. Also, this looks to be powder coated with decals, so they may not have bothered with masking (just a guess).

  • Jarrod, what is that hole and why isn’t there a picture of it.

  • AaronBenjamin

    Handlebar is the best part.

  • Christopher Peltzer

    I hope this gets ridden, such a sick build.

  • Angelo Medina

    I try to overcome this, but… compact geometry on track bikes always seem to be a -1 in my book … What can i do to make this stop¿

  • Beau

    What is that cog? Is it a freewheel? I think I see a lockring, but I can’t tell. Anybody know?

    Yes to trackish bikes. Just enough black, just enough silver. Subaru WRC blue/neon always a win in my book.
