With its modern geometry, short wheelbase and light weight, the BASEMENT is the best option for those looking for a fast and agile bike. With the flip-flop hub you can switch from singlespeed to fixed gear in no time.BASEMENT is about high-quality materials and components combined to create a first-class frame construction.
Cr-Mo 4130
BASEMENT's frame construction is focused on design and comfort. That's why the frames are made with a special steel alloy of chromium-molybdenum SAE 4130, which is also used in the aviation and motorsports industries.
The frames are built with double-butted tubes of variable thickness, which allow the application of the right thickness in the right place, guaranteeing durability without adding unnecessary weight. The low stiffness results in a very comfortable ride. The resistance of chromium-molybdenum is 80% higher than that of aluminium, the latter being stiffer, less comfortable and more susceptible to damage.
Handlebars
When it comes to choosing handlebars for your bike, the question usually arises as to whether you want the comfort of riser handlebars, the aggressiveness of drop handlebars or the versatility of bullhorn handlebars? What works best for you?
But why do you have to choose just one type, just one experience?
To help you decide, RIVA has equipped the BASEMENT with all three handlebars so you can explore all the possibilities of your bike.
Singlespeed or fixed?
The BASEMENT comes with a flip-flop hub so you can quickly and conveniently switch between fixed gear and singlespeed mode.
The flip-flop hub comes with two sprockets, one on each side of the hub. There is no freewheel in fixed-gear mode. This means that when your pedals turn, your legs turn with them. The rigid gear is ideal if you really want to feel connected to the bike and the road. If you prefer a more relaxed ride, where going downhill feels like riding a regular bike, then simply reverse the rear wheel and use the sprocket with the freewheel.
No matter what you choose, fixed gear or single speed, the classic rim brakes front and rear ensure that your bike comes to a stop when needed.
