Marin Nicasio RC Gravel Bike


Shipping Calculator

"So stylish it hurts" was the feedback given by who recently reviewed the new Marin Nicasio RC and you will quickly agree when you lay your eyes on this steed. 
Who is this bike for? well it is for if you want to commute to the office - but not on skinny rubber and certainly not with a drop bar in your hands. You fancy yourself a wanderer who often chooses the dirt path over the paved route. You’re a student on a budget who desires the luxury of a reliable bike to zip between classes without the hassle of having to regularly maintain it. You are a social butterfly who needs a stylish, two-wheeled vehicle to meet up with friends on a whim. Your mudroom currently has a vacancy for something that’s as exciting to look at as it is to ride. If you fit any of those descriptions, then this is the bike for you.
For comfort and old-school style, there is the chromoly frame and fork, swept back handlebars together with gum wall 47mm balloon tyres. You’ll even notice the customised shifter, designed to look like old friction shifters from the 80’s.

Where this bike does depart from the old school is in the high tech drivetrain. The shifter is indexed for the Shimano 8 speed nexus internal hub. It's easy to use, being able to change gears whilst stationary or whilst moving. 

The whole set up is almost maintenance free too. Being a sealed unit the nexus hub requires minimal servicing, so too the anti-corrosion chain and hydraulic disc brakes.  

When you add these to the fenders, make it rain day friendly too. And if you plan to go long, two sets of bottle bosses and mounts for both front and rear racks let you equip your new Marin with everything you need for all-day adventures.



  • Double butted chromoly steel frame and fork
  • Shimano Nexus 8-speed internally geared rear hub
  • Shimano Hydraulic Disc Brakes
  • Robust, 32-spoke, doublewall, alloy rims
  • WTB Horizon 650B Tyres
  • Full front and fender eyelets plus rear rack mounts
  • Weight: 14.5kg (54cm including pedals)

All of our bicycles come with a Free Pro Build valued at $99. This means that your bicycle will be pre built by our professional mechanics. For your convenience, safety and comfort all our bikes are fully assembled prior to delivery. The bike is then packaged back into a box for secure shipment.


When your bike arrives, all you have to attach is the front wheel, the handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, and the tyres have been pumped up (please note upon arrival, in some cases you may need to add more air to tyres).

Most companies simply sell you the bike as it comes from the factory, which will require significant know-how to get your bike on the road. Currently we are the only Australian company providing this service, and have the 14 day test ride to back it up.

All tools are provided with the bike.
