Rubber Side Down (RSD) bikes may only have been around since 2012, but the company’s history stretches back over 25 years. The Toronto-based company’s owners fell in love
with their first hardtail bikes decades ago, and as their passion for
the sport grew over the years, they decided to start building their
own. RSD is a relatively small company that only produces mountain bikes, and they design their bikes to be versatile enough to be
ridden nearly anywhere.
WHO IS IT MADE FOR?
The Mayor looks to rule the fat bike world with a campaign
built on versatility, performance and value. The Mayor may not be
the only bike in most riders’ quivers, but it is an affordable way
to jump into the fat bike world without giving up much on performance. This is far from a dedicated race bike, but we raced it. It
would be great on snowmobile trails, but we enjoyed it on the dry
and dusty summer SoCal trails as well. This is a fat bike that’s
exactly what you’d expect from looking at it. It’s not going to win
any cross-country races, nor is it going to be a downhill superstar.
Instead, the Mayor is designed for fun all the way down the trail.
WHAT IS IT MADE FROM?
RSD builds the Mayor from aluminum with hydroformed 6061
tubing. The frame sports Boost 197-millimeter rear-axle spacing,
a tapered head tube and enough tire clearance for tires up to 5
inches wide. The fork is a custom-built carbon RSD with no travel
but plenty of clearance.
WHICH COMPONENTS STAND OUT?
The price is the impressive standout here. This is a high-quality
fat bike with a carbon fork that comes in well below the $2000
mark. The components are a solid mix of Sun Ringle, SRAM,
Easton and Race Face. While it may not be the ideal kit for winning
a fat bike national championship, it’s certainly light enough for
most riders and more than reliable.
Simple but elegant: The RSD uses a simple single-ring drivetrain
with a Race Face crank and SRAM X7 derailleur. It’s not the flashiest build, but it gets the job done.
