Before every ride, it is very important to check the tire pressures. Too low of a tire pressure
will make pedaling more difficult, decrease range, and can cause pinch flats. The recommended
pressure range is printed on the drive side of every tire, so make sure to check the label on the
tire before inflating it. When removing the bike from the packaging, the tires will be at too low
of a pressure to ride safely. This is because the bike will have been inside the box for at least a
month before being delivered, and in this time the tire pressure will slowly decrease.
•
The Aero comes with 700 x 38c tires. Depending on the year and batch, the pressure should
be about 70PSI. A good rule to follow is to pump up bicycle tires to 5PSI below the max recom-
mended pressure printed on the tire. If the pressure range is 35PSI to 65PSI for example, the tire
should be pumped up to 60PSI. If riding in the rain or on off-road trails, it is a good idea to lower
the tire pressures closer to the minimum recommended pressure to maximize traction.
•
Make sure to check the tire pressures about once a week. Although tires may seem air tight,
the rubber is still a semi-permeable membrane that will slowly let air molecules through. This is
why bicycles have flat tires after being left alone for a couple months. If a tire goes flat overnight
however, the inner tube has a slow leak that will either need to be patched or replaced.
•
The Aero uses presta valve inner tubes. The rims are not compatible with tubeless tires. Espin
uses tires with the standard level of puncture protection, but for maximum puncture protection,
we recommend using either Tannus Armour Inserts or Mr. Tuffy Tire Liners. Check your tire size
and the charts on their websites to see which sizes to get. To maximize traction in icy winter
conditions, there are options available in most tire sizes for studded tires. For specific recom-
mendations for which winter tires will work with your model, contact our tech team at hello@
espinbikes.com.

INSTALL THE PEDALS
5 .1 Remove the pedals from the parts box.
One is labeled R for right (drive side) and the
other is labeled L for left (non-drive side). The
left pedal is threaded opposite from all the
other bolts, READ THESE INSTRUCTIONS THOR-
OUGHLY!
5 .2 The right pedal is threaded normal-
ly. Thread it into the crank arm clockwise.
Once it is threaded in a couple turns, it can
be quickly threaded in the rest of the way by
holding the flats of the pedal axle with the
provided tool and pedaling backwards, as
shown in Figure 12. Tighten this well.
5 .3 The left pedal has left-hand threading,
meaning it threads COUNTER-CLOCKWISE.
Once it is threaded in a couple turns, it can
be quickly threaded in the rest of the way by
holding the flats of the pedal axle with the
provided tool and pedaling backwards, as
shown in Figure 13. Tighten this well.

5 .4 Using the wrench to thread in the pedals
is just a tip for threading them in quickly. The
wrench is only necessary for the final tight-
ening of the pedals. The pedals should be
able to be threaded in all the way with just
your fingers. If screwing the pedals in be-
comes too hard after just a couple turns, STOP
and make sure that the pedals aren‘t getting
cross-threaded. If the pedal isn‘t threaded in
completely straight, the threads of the pedal
and crank arm could be getting damaged.
