SRM SmartIT Training Bike
Introduction
Welcome to the next generation of SRM Indoor Training. The SRM Smart IT, developed by cyclists for cyclists, is the ultimate, no-compromise indoor training experience. The third generation SRM SmartIT enables many modes of operation including:
- Standalone operation by power or gear
- Interval operation by power or gear
- Control by SRM SmartIT app,
- Control by external app such as Zwift, Trainerroad.
SmartIT includes 11-speed shifting to provide realistic ride experience similar to riding on the road, enabling the greatest riding experience and training control. The kinetic energy stored in the rotating flywheel enables a lifelike and realistic simulation of real road riding, and the sturdy construction enables all-out intervals and efforts to enable the best training platform.
Important Safety Instructions
SmartIT has a number of moving parts that may cause serious injury if touched during operation. Do not touch the moving parts including spinning flywheel, gears, cranks/ pedals or chain during use. Note that the flywheel may become extremely hot during use When in use, all people other than the rider should be a safe distance (at least 1m) away from the unit. The seat-post and the handlebar post are height-adjustable and not secured by springs. While making any adjustments to the seat and bar height, be sure to hold on to the post to avoid the posts hitting the frame or pinching hand/fingers. The brake electronics are located in the black box which is attached at the back of the brake. The black box is not waterproof, so when cleaning the SmartIT, do not let water get inside the brake box. Disconnect the power and clean the box only with a damp cloth. Before cleaning make sure to disconnect the trainer from 12V DC power.
What is included
Setting up your SmartIT
Placing the SmartIT
Ensure that the SmartIT is installed on firm flooring, and is level and
balanced before use. The four extendable feet can be adjusted in and out to
accommodate small variances in the level of the floor.
Adjusting the Seat Position
The SRM SmartIT is designed for riders between 165 cm (5’5’’) and 200 cm
(6’7’’) of height. The seat height and position are fully adjustable. The
saddle and the handlebars can be adjusted continuously, as shown by the red
arrows. Two wheels make it easy for one person to move the SmartIT
Clamping the seat and handlebar sliders
Adjust the seat and handlebar position by loosening the appropriate lever,
moving the slider, and tightening the lever. Once the position is adjusted,
the levers can be moved out of the way by lifting, turning and letting them
lock into place in the desired position
Adjusting the Handlebar
The distance between the seat and the handlebar can be significantly increased
by removing the handlebar slider with stem facing backwards, and re-installing
it facing 180° so that the stem faces forwards, using the following procedure:
- Remove the handlebar from the stem (see picture)
- Remove the end-cap and take our the slider
- Rotate the slider and re-install so that the stem is facing forward.
- Re-attach the handlebar (use 4 Nm for the screws on the stem) and end-cap
Gears and Drive-train
The drive-train of the SmartIT includes an 11- speed gear shift. This allows a
realistic riding experience, since the gear can be changed as the SmartIT
Brake changes the pedalling resistance, just like if you were going up or down
hills. Set up and adjust derailleur as for a normal bike.
Installing pedals
The SmartIT is delivered without pedals. Please, install your pedals according
to the installation instructions of the pedal manufacturer.
Power Supply
Plug in the power cable into the socket to power the SmartIT. The socket is
located on the bottom side of the frame just below the fork. Lift the frame on
the front side to reach the socket. Be careful not to rest the power supply
connector on any object as it may damage the connector
Remote
Please, install the remote on the handlebar using the included cable ties. To
activate the Remote, plug in the four pole plug in the four pin socket on the
back of the remote. As soon the remote is supplied with power, it will start
to run and the current firmware version will be displayed.
Getting Started
Before using the SmartIT for the first time, some basic steps need to be completed. For more details on all available options, please refer to the respective chapters in this guide
Remote Button Definitions
- Short key press : switches between interval and normal mode
- Long key press : switches between control by power and control by resistance
- Short key press : start/stop interval (interval screen)
- Long key press : reset interval counter (interval screen) or reset total time (basic screen)
- Short key press : increases resistance or power
- Long key press : increases the increment
- Short key press : decreases resistance or power
- Long key press : decreases the increment
SmartIT Ride Modes
The SmartIT provides two different ride modes:
Ride by Gear:
Ride by gear means that you can set the resistance of the Smart brake. The
resistance ranges from 0-100% (low to high) and can be adjusted in increments
of 1%. With this mode you can easily simulate real riding conditions such as
hill-climbing, and training for time-trials or sprints.
Ride by Power:
Ride by Power means that you can set the target power of your training. The
brake will continually adjust the resistance to reach the target power at the
cadence that you are riding at. To reach your target power constantly, you
must pedal at a constant cadence. The power can be adjusted at increments of 5
Watts. This is the perfect training mode for workouts with defined power
levels, such as power zones as a percentage of your Functional Threshold Power
(FTP).
Interval by Gear or Power:
Both ride modes provide an Interval Mode. With the Interval Mode you can
set up your upper and lower resistance(Ride by Gear) or target power(Ride by
Power). To enter the Interval Mode, short press the MODE button. Set up the
lower value using the arrow keys. Press the SET button to start the interval.
Use the arrow keys to adjust the value. The interval timer shows you the time
you have spent in your current interval. The total number of intervals is
tracked by the interval counter. To reset the interval counter long press the
SET button. Refer to 6.7 “Interval Start Preferences“ to set your preference
for starting on the upper or lower interval.
Connecting to external apps (e.g.. Zwift)
Ensure that External Control is enabled from the Settings menu and pair your
sensors including Heartrate to SmartIT. You can pair SmartIT as a controllable
trainer, and also pair the cadence, heartrate and power source data. Heartrate
is only available if the external control is on a Bluetooth device. To get the
best riding experience, always pair the controllable device (SmartIT-123), NOT
the PowerMeter. The riding experience can be adjusted using a few settings on
SmartIT as well as the application. Refer to 6.4 Personalising the Brake Speed
for more information. Applications also vary the ride experience. Within Zwift
you can change the “Trainer Difficulty” within the settings menu. It is
recommended to start this at around 20% on the slider and adjust as necessary.
Connecting the SRM SmartIT Apps
The Smart IT app is available in the app store for Ipad and Android devices.
Search for “SRM” and scroll to find “SRM Smart IT”. The Smart IT app enables a
number of key capabilities, including:
- SmartIT setup, including pairing of sensors such as PowerMeter, HeartRate belt
- Firmware upgrades for the SmartIT Electronic Brake and Remote units
- Personalising SmartIT for the rider to enable accurate simulation of kinetic energy/speed, and also training zones
- Defining and using your favourite workouts
- Displaying live data
Settings Menu
To access the SmartIT settings, press MODE and SET at the same time. You can navigate with the arrow key between the individual menu entries.
Pairing the PowerMeter
Press SET to enter the PowerMeter menu. Press SET again in the serial tab to
search for the Powermeter. When the Powermeter has been found, the status will
switch to connected and serial number will be shown in the serial tab. To set
the zero offset, navigate to the Calibration Value (Cal. Value) and press SET
to search and store the received Zero Offset. The current power and cadence
(rpm) is displayed in the “Data” tab if the PowerMeter is in use. Press MODE
to go back in the main menu.
Pairing Heartrate
Navigate to Heartrate and press SET to enter the menu. Press SET again to scan
for a Heartrate device. When the Heartrate device has been found the Status
will switch to Connected and the Serial Number is displayed in the serial tab,
also the current Heartrate is displayed in the data tab. Press MODE to go back
to the main menu and save the changes
Pairing sensors to PC8
Please refer to PC8 User Manual
Personalising the Brake Speed
To personalize the brake performance you can adjust four different options:
Power Mode:
The Power Mode determines how quickly the brake reacts to a new target power.
A higher value leads to faster control. On a high setting the brake may
overshot the target power, whereas in a lower setting the brake adjusts
slower. The default setting is 4.
Gear Mode:
This determines the total power controller action in the Ride by Gear mode, so
how quickly the brake reacts to reach a new target resistance. A higher value
leads to faster control. On a high setting the brake may overshot the target
resistance, whereas in a lower setting the brake adjusts slower. The default
setting is 5.
Target Zone:
The Target Zone describes the zone around the target power value (only in
control by power). No controller actions are done when the measured power is
within this zone. This ensures a smooth ride feeling with at a steady target
power. The default setting is +/-5 %.
Steady Gain:
Steady gain relates to the Power Mode setting. After the target power has been
reached, the steady gain will dampen the brake control. This further improves
the smoothness of the ride feeling. A higher value means more continues
intervention by the brake, whereas a lower value gives more freedom with
slight power changes. The default setting is 25 %. We recommend using the
default settings.
Speed Sensor
SmartIT provides a speed calculation based on the Kinetic energy in the
flywheel, and the rider/ bike weight. The PC8 or other devices can be paired
to Smart IT to display or record Speed and Cadence. To scan for the speed
sensor in your device, refer to the manual of your head unit. Please, set the
circumference to 2095 mm. This value is used as a basis for the speed
calculation. The speed is shown in km/h. Please, set up your rider and bike
weight according to chapter 6.9 Ride Simulation Settings – Bike and Rider
Weight.
Power smoothing
Power Smoothing introduces a rolling average of individual power values for
display on the remote, with the number of individual values defined by this
setting. It does not affect the transmission of power values from SmartIT to
external apps or programs.
Interval Start Preferences
In the interval settings, the start position for the intervals can be changed:
- Man (Manual): Interval starts with the low level after switching to interval screen. You have to press SET to start the Interval.
- Auto (Auto): Interval starts with the high level after switching to interval screen. You have to press SET to stop the interval.
To edit the interval start press SET. With the arrow buttons you can switch between Auto and Man (Manual) and press SET again to set your preference.
Enabling and Disabling External Control
The SmartIT brake can be controlled by external software via Bluetooth LE
and ANT+. In the default settings all three possible connections are enabled.
In the case you do not need all connection types and you have connection
problems caused by other devices, you can disable connections you do not want.
If you don’t have problems with the connection it is highly recommended to use
the default settings and keep all connection types enabled. To enable or
disable a connection navigate to External Control and press SET to enter the
setup. Navigate with the arrow buttons between the connection types and press
SET to disable external control.
Ride Simulation Settings – Bike and Rider Weight
The ride simulation settings make a realistic riding experience possible.
Enter the rider’s weight and the bike weight via arrow and SET keys. The
rotation speed of the fly-mass allows a realistic speed can be calculated, and
is shown in the display as well as sent out via BLE and ANT+. The speed can
also be displayed in the PC 8 if paired with SmartIT. The Offset Step Size
allows the user to apply increased or decreased resistance when in external
control mode – effectively increasing/decreasing the gearing of the drive-
train.
Maintenance and Care
The components of the SmartIT meet the highest quality standards and are designed for hard workouts and heavy usage. In order to enjoy the SmartIT indoor cycling experience for a long time, please make sure you follow a regular care and maintenance program including the following steps.
Daily Care
After every workout, please clean your SmartIT with a damp cloth to remove all sweat or dust from hard training. Sweat is extremely corrosive so it is important to clean after every ride. Gently dry all parts with a soft cloth.
ATTENTION : The brake electronics are located in the black box which is attached at the back of the brake. The black box is not waterproof, so when cleaning the SmartIT, do not let water get inside the brake box. Disconnect the power and clean the box only with a damp cloth.
Monthly Care
Where necessary:
- Please clean the chain with a cloth soaked in chain-oil and wipe off excess chain-oil after cleaning
- Please check the gear shifting and adjust if necessary
- Please remove the seat-post and handlebar post and clean them from sweat and dust. Make sure to remember your saddle and handlebar position.
- Connect your Smart IT with the SmartIT IOS App and check for firmware updates.
Yearly Care
Where necessary:
- Please check for smooth and quiet operation of all moving parts
- To protect your SmartIT frame from corrosion, we recommend to treating the frame periodically with a silicone polish. Silicone polish is available in bike shops or automotive stores.
