Product Description

Smart and quiet the Saris H3 Silent turbo trainer is a great way to boost your winter training regime. Used with Zwift, your indoor cycle training can be fun as well as rewarding.

Compatible with Zwift

When it comes to indoor bike trainers, the most frequently asked question is: how quiet is it? Taking this to heart, our Wisconsin-based team put this query under the microscope and set a goal to build a trainer so quiet, that the only sound is that of your drive train.

The result? A direct drive smart trainer that touts a sound specification of 59 decibels at 20 mph. In other words, the H3 is five times quieter than previous generations, making it the quietest smart trainer to ever leave our doors.

Following the Saris direct drive smart trainer legacy, the H3 features the same reliability and durability as its predecessors. Each H3 is made from cast and machined aluminum sourced from America’s heartland. Encased inside are components meticulously calibrated to measure power, speed and cadence, as well as a precision-balanced flywheel - all built to handle 2000 watts and replicate a 20% climbing grade.

Tested to withstand heavy training, the H3’s internal cooling system will keep the electromagnetic resistance system working – and accurate – long after your legs have given out.

Product Features:

  • Quieter Than Ever: all new drive system shaves decibels off previous generations.
  • Precise Training: +/- 2% power accuracy.

Turbo Trainer Guide

 

Turbo Trainers Guide

How do turbo trainers work?

Most turbo trainers work by fixing to your bike frame with a clamp around the quick release skewer of your rear wheel. This puts your bike into a position where the rear tyre will sit on the turbo trainer’s roller drum. As you begin to pedal, your rear wheel spins and the roller drum turns.


Types of resistance

Wind resistance

Wind/Fan

Magnetic resistance

Magnetic

Fluid resistance

Fluid

Electromagnetic resistance

Electromagnetic

A great value choice if you’re looking for your first turbo trainer. 

When you pedal, the fan spins creating air resistance. Resistance is smooth and progressive for a life-like experience.

Magnetic turbo trainers are the most common. They use a spinning metal disc which spins relative to magnetic discs to generate drag. 

Most will have multiple pre-set resistance settings you can choose to make the ride harder. 

You change resistance either by manually changing the setting on the turbo trainer or with the use of a remote positioned on your handlebar.

Fluid turbo trainers offer very smooth, lifelike resistance by spinning a thick fluid within a sealed chamber. 

Fluid trainers offer progressive resistance, so the harder you pedal, the harder the resistance becomes, just like real-road riding conditions.

Electromagnetic turbo trainers are becoming more popular. 

Just like magnetic turbo trainers, these use a magnetic field to generate drag on a metal disc. However, resistance can be changed wirelessly for use with apps and devices. 

These turbo trainers give you the greatest level of control over the exact resistance you want.

  • Low budget
  • Smooth progressive resistance

 

  • Multiple resistance settings to challenge yourself
  • Max resistance settings can be very high
  • Within budget for many
  • Quietest resistance offering. Perfect to keep the family happy
  • Very smooth progressive resistance for a lifelike feel.
  • Refined resistance control
  • Use with apps and devices
  • Can generate very high resistance levels
  • Automatic resistance opens up versatile training sessions

What is a smart turbo trainer?

Every big turbo trainer brand now has a range of smart turbo trainers. They are the new big thing in the indoor cycle training market. These turbos use electromagnetic resistance and can be synced wirelessly with ANT+ and/or Bluetooth Smart to your 3rd party training apps, devices, power meters and sensors. This connectivity can greatly enhance your training regime and open up fun virtual training apps to keep you motivated.

Zwift, BKOOL and other training apps can automatically change the resistance of your turbo trainer opening up the possibility of sprint training, intervals and even simulate climbs of up to 20% gradients.

You can also use apps to pre-load a set training plan to follow or plug-in GPS data and ride famous cycling routes from around world while viewing the route on your computer or smart T.V.


Zwift virtual training app

Zwift logo


Zwift is powerful training app where you can challenge yourself against other real-world riders to a race in a 3D virtual environment. Zwift distinguishes itself from other training apps by offering a video game-like experience with immersive virtual worlds for you to ride in. As well as structured workouts, Zwift gives you the opportunity to join group rides with other riders of a similar ability and even compete in online races. It’s a great way to mix up your training and have a bit of fun.

Your power is measured by the watts you produce, which is then used to move you forward through the 3D environment. Speed is also adjusted by your height, weight and even the road gradient for added realism. You can learn with our Zwift guide

Zwift is compatible with a wide range of turbo trainers, indoor bikes and rollers with ANT+ or BLE enabled. Read our Zwift Compatibility guide for more information.


What is a direct drive turbo trainer?

Direct drive turbo trainers work in a different way to a traditional turbo trainer. Your bike is attached to the drive unit via the cassette, so you do away with the rear wheel entirely. This does mean it takes a bit longer to setup than a traditional turbo, but you get some useful benefits in return.

1

The flywheel is moved to a central position

This offers a more lifelike feel compared to a traditional turbo where the flywheel is placed behind the rear wheel.

2

Precision performance metrics

Most direct drive turbos are compatible with a range of power meters, sensors, apps and devices to let you track your performance data. With no rear wheel, there is no tyre slippage or roller drum tension to cause inconsistencies in your data.

3

Quiet operation

Direct drive turbos are much quieter than a standard turbo trainer as there is no roller or tyre friction to create noise.

4

No tyre wear

No rear wheel means no tyre. You don’t have to make that choice between wearing down your racing tyres or wrapping a spare onto your wheel to protect them.


Bolt-thru axle compatibility

For bikes that use a bolt-thru rear axle, a compatible axle must be purchased to fit your trainer. These are brand specific to the trainer, the thread pitch and diameter must be the same type used on your bike. Click here to identify your pitch thread


What accessories are available?

Training mat

Training mat

A training mat will protect your floor from marks and damage, as well as sweat. These mats help prevent you skidding around when you’re really powering through and they will soak up some noise.

Sweat towel

Sweat towel

Indoor cycle training will make you sweat. These small towels will cover your top tube to prevent damage and corrosion.

Riser blocks

Riser blocks

With a standard turbo trainer, your rear wheel will be slightly raised, giving the feeling of descending. A riser block will lift your front wheel for a more realistic cycling position.
