USER MANUAL
Congratulations! You have purchased a piece of engineering that we, at Ridea, have made
with passion. Enjoy your rides with your Ridea component as much as we enjoyed making it.
Thank you for your purchase of a Ridea product. Please read thoroughly this user manual before
proceeding with the installation of your new Ridea crankset. Although the installation process
is easy to follow, we recommend taking your crankset to a professional bicycle mechanic with
specialized tools to perform the installation.
IMPORTANT NOTICE
Important note: Tightening to the recommended torque is important for your safety and for the
performance and durability of your bicycle. Always use a torque wrench.

Chainring installation (chainrings not included)
1. Use a 4 mm hex wrench to tighten the chainring screws to 10 N m. Do not tighten to the final
torque one screw before tightening the others. Instead, alternatively tighten each screw,
switching between them, until all of them reach the recommended torque.
Crankset installation
2. Refer to bottom bracket manufacturer’s user manual to perform its installation. The spindle
diameter of your PNEUMA crankset is indicated in the spindle: a D24 mark refers to 24 mm
spindle diameter, while a D29 refers to 29 mm. Note: Crank arm code, located in the inner
side of each crank, near the pedal interface, also references the spindle diameter. The code is
like LF29 R-175L or LF24 M-170R. The number in bold, bolded here for your reference,
indicate the diameter of your spindle in millimeters.
3. Identify the left and right crank arms. The code in the inner side of each crank will guide
you. The last letter of the code (LF29 R-175Lor LF24 M-170R, bolded here for your reference)
denotes the side of the crank: L for left and R for right crank.
4. The spider comes preinstalled in the right-side crank arm in the standard position. The spider
has three possible positions, described below.
a. Standard position: The central position (marked as “0”) is the standard and recommended
for most riders and conditions. This is the position already preinstalled. If you do not want
to change the position of your spider now, jump to step 5 after checking that the torque
of the locking ring is 30 N m.
b. Climbing position: Starting from the standard position, rotate the spider one step in
counter-clockwise direction, this position is recommended for climbers and it is marked in
the spider as “+10”.
c. Rouleur position: Starting from the standard position, rotate the spider one step in
clockwise direction. This position is recommended for rouleur riders and it is marked in
the spider as “-10”
5. Once you have chosen your desired position, apply grease to the contact areas between
the spider, the right crank arm and the locking ring, as well as the threads of the locking ring
and crank. Use the included Ridea BB tool and a 10 mm hex wrench to tighten the locking
ring to 30 N m. Clean the grease excess. Attention: if installing the SPM2 power meter
spider, the crank must always fit in the crank slot of the SPM2. Never try to install the crank in
the opposite direction.

PNEUMA CRANKSET REMOVAL
1. Loosen the preload adjuster bolt, with a 2 mm hex wrench, and hand-turn the preload adjuster
towards the crank.
2. Use an 8 mm hex wrench to remove the left crank arm. If required, use a rubber mallet to tap
the crank to help you remove it.
3. Slide the right crank arm and the spindle out of the bb shell. If required, use a rubber mallet to
tap the spindle from the non-drive side to help you remove the crankset.
6. Grease the threads and spindle-crank interface in the right side of your crankset. Fix the
spindle to the right-side crank arm. Use an 8 mm hex wrench to tighten it to 30 N m. Note:
spindle is symmetrical. Therefore, there is neither right nor left side.
7. Provisionally insert the right crank arm unit in the bottom bracket and measure the chainline. If
needed, you can adjust it with the appropriate chainline adjusters. These should be installed
in the crankset spindle, between the bottom bracket and the crankset.
8. Take the crankset out of the BB to apply grease in the bearing contact areas.
9. Insert the right crank arm unit into the BB shell with the appropriate chainline adjusters. If
required, use a rubber mallet to tap the crank to make sure that the spindle is fully inserted into
the BB shell.
10. Turn the preload adjuster of the left crank arm until it contacts the crank arm.
11. Grease the threads and spindle-crank interface in the left side of your crankset. Fix the
spindle to the left-side crank arm. Use an 8 mm hex wrench to tighten it to 30 N m.
12. Turn the preload adjuster until it contacts the bottom bracket. Hand-tighten it. Do not over
tighten it, or the cranks may not spin smoothly.
13. Tighten the preload adjuster bolt to fix preload adjuster’s position. Hex wrench 2 mm.
Maximum torque: 1.5 N m.
14. Check the crankset for play by moving the cranks laterally. Check that the cranks rotate
freely.

RIDEA SPM2POWER METER SPIDER
Getting ready
First charge
Ridea SPM2includes a partially charged internal battery. Before using your power meter on a
ride, it is recommended to perform a full charge of the battery. Check the “Battery” section to
know more about charging your unit.
Connection to a bicycle computer or smartphone
Ridea SPM2is compatible with ANT+™ and Bluetooth® LE protocols. Most cycling computers
preferably use the former, while most smartphones are only compatible with the latter.
Your power meter must be activated in order to connect to a compatible display unit. To
activate it, rotate the cranks. If the power meter is activated, the LED will flash a blue light every
eight seconds while the cranks are moving.
Follow the manufacturer´s instruction manual of your cycling computer or smartphone app for
connecting new devices.
Connection to Ridea smartphone app
Ridea SPM2app can use the Bluetooth® of your smartphone to connect both devices.
Activate the Bluetooth® function of your smartphone and open the app.
Your power meter must be activated in order to connect to your smartphone. To activate it,
rotate the cranks. If the power meter is activated, the LED will flash a blue light every eight
seconds while the cranks are moving.
Click the “+” bottom in the app to detect your SPM2unit. Select the right power meter unit
and both devices will link together.
Zero offset
A zero offset, also called calibration or zero reset, is a procedure to make sure that the data
given by your power meter unit is accurate to the current conditions.
Ridea SPM2has several technologies that allow an automatic zero offsetting without the need
of user intervention. This means that you do not normally need to perform a zero offset to obtain
precise data of your rides. Although not necessarily required, you may perform a manual zero
offset before your first ride and also after maintenance work has been done in the crankset; like
re-installation, change of chainrings and/or pedals, or retightening of bolts. You can also
perform a zero offset if you have not ridden your bicycle for a long period of time.
Ridea SPM2also adjusts itself to compensate temperature changes. In case there is a drastic
change of temperature, like when you take the bicycle out in the winter, but you still want
precise data at the very beginning of your ride, it is recommended to wait a few minutes until
the internal components of the power meter have reached the ambient temperature. Then you
can perform a manual zero offset or let the unit adjust itself automatically.

6
Performing a manual zero offset (optional)
1. Rotate the cranks to ensure the power meter is awake. A blue light will flash every eight
seconds to confirm that the unit is awake.
2. Select the zero offset, calibration or zero reset function of your bicycle computer or smartphone
app.
3. With compatible display units, you should see a confirmation message when the zero offset
is finished.
To charge the integrated battery of the SPM2, connect the included magnetic charging cable to
a 5V USB charging source and to the unit’s charging port (Caution: Make sure than the port is
clean and dry before plugging in the cable). A green light will flash briefly to confirm
connection and then the LED will turn red during charging. Once the battery is fully charged,
the LED will turn off to let you know that you can unplug the charging cable.
A full charging run can take around 3 to 4 hours. DO NOT use your power meter while
charging the battery.
The integrated battery of the SPM2allows up to 120 hours of riding after a full charge. In
compatible devices, the screen can show five levels of battery life (sometimes regarded as:
new – good – ok – low – critical). Once it reaches the “low” level, the power meter will have
several hours of normal and accurate measures. It is recommended to charge the battery before
it reaches the “critical” level to avoid measure inaccuracies.
The power meter unit will enter standby mode after five minutes of inactivity to save battery life.
To activate the unit again, rotate the cranks.

MAINTENANCE AND CARE OF THE SPM2
POWER METER SPIDER
Here there are some simple guidelines to prolong the life and to keep the performance of your
power meter:
·Use water or mild soap and a soft rag or sponge to clean your power meter.
·DO NOT use high-pressure water over your power meter to avoid water from
soaking into the unit’s electrical components.
·Avoid direct contact of degreasers or corrosive cleaning products with your power meter.
·Store your power meter at a temperature range of -20 – 50 °C.
·When not riding your bicycle, try to avoid power meter exposure to direct and strong sunrays.
·Before connecting the charging cable, please ensure that the magnetic charging port is clean
and dry.
MAINTENANCE AND CARE OF THE CRANKSET
Clean your crankset with water and mild soap.
Check your Ridea product for wear, damage of any type and looseness before every ride and
immediately after any crash or fall. DO NOT ride your bicycle if you find any damage on your
Ridea product or in any other component of your bicycle.
Maintenance intervals greatly vary with riding conditions, distance ridden and intensity of your
rides. In case of doubt about the status and condition of your crankset, please stop riding and
check with a professional mechanic to perform a maintenance service.
It is important to periodically check the tightening torques of the bolts and to check if there is
any play in the cranks (try to move the cranks laterally to feel if there is any play). If you feel any
play or if the bolts are loose, tighten them to the correct torque again.
Less often, it is recommended to perform a full removal, cleaning, inspection, re-greasing and
re-installing of your crankset and bottom bracket unit.
DISPOSAL OF ELECTRONIC DEVICES
We desire you can use your Ridea SPM2 for many years. Although eventually, you will have to
replace it. This is an electronic device, do not dispose it in general household garbage.
Dispose it accordingly to local regulations in a recycling center or other suitable facility.
