The Pro Series Trainer will fit most 29x2" tires, and some tires up to 29x2.35" depending on knob height and casing/rim size.Be sure to check that the tire does not rub on the floor with this setup, especially when carpet is involved.

The max rear dropout spacing is 135mm on our Pro Series. However our Classic Series frames work with our 142x12mm thru axel adapter. This adapter opens the range up to 142mm (Classic Series Only). 150 and 170mm dropouts are not accommodated on either frame style.

Syntace and Maxle/ABP are the two compatible thru axle systems that allows our 142x12mm thru axle adapter to work with our Classic Series frames only.

Good question! Check out our getting started page or our side-by-side trainer comparison guide.

When you're riding your bicycle outside, wind resistance increases exponentially according to your speed. It's more than twice as difficult to ride at 20 mph than at 10 mph. The best stationary trainers offer built-in progressive resistance: pedaling faster or shifting the gears on your bike results in increasing resistance. With linear resistance, you lose this road-feel. Pedaling faster or shifting your gears has little effect, other than spinning your rear wheel faster.

A trainer is designed to work on strength and endurance training and typically provide more resistance than rollers. Riding rollers promotes good balance and a smooth pedal stroke. Many people incorporate both in their off-season training. So, it depends on your training goals as to which one is right for you.

For all trainers, you will want to make sure that the tire does not slip on the roller when accelerating or sprinting.Also, make sure that the tire pressure is within the recommended specification labeled on the tire by the manufacture.

Black Knob (Wind & Mag/Mag+) - For trainers using our black resistance knob to move the resistance unit up against the rear tire, you will want to turn the knob 2.5 to 3 complete turns once the roller is touching the rear tire of the bicycle.

Yellow Clutch Knob - Our newly designed clutch knob works similar to a gas cap on a vehicle.Twist the Clutch Knob to the right until you hear the Clutch Knob click.Once you hear the click you are at the correct pressure between the resistance unit and rear tire.

It is possible that the quick-release skewer of your bike's rear wheel may not fit well in the trainer's cones. Use the skewer provided with the trainer for the best fit. If your bike does not have a rear wheel skewer, but uses nuts, you may need to replace the nuts with "track nuts," which have a built-in flange and can improve the fit of the bike in the trainer. For replacing or changing axle nuts, please see your local bike shop.

Yes. You can purchase new resistance units if your original trainer was manufactured after 2005. Please call your local dealer or our customer service department for details: 1-800-783-7257.

CycleOps Power utilizes ANT+ technology to ensure a robust and reliable connection between the various sensors used in our products. However, there is a limit to the number of sensors that can operate in a given environment. Practically speaking, when riding by yourself or with others using less than 30 total ANT+ sensors, you should see no more than a 1% loss in data due to communication errors in your sensors. However, in an environment with more than 30 total ANT+ sensors you may see an increase in communication errors.

All sensors operating in a group environment should be positioned at least 6.5 feet apart from each other to ensure minimal signal interference between devices. We recommend that no more than one head unit is paired to the PowerBeam, otherwise it may drop signal or act erratically.

Riding indoors on a trainer/roller will generate much morefriction than when riding outdoors because our wheels are always touching thesame spot of the roller drum, this will cause extra heat and friction thatmost tires designed to be ridden outdoors cannot handle. We recommend thatyou either use an old set of tires to prevent wearing your nice outdoor onesor look into a trainertire that is specifically designed for use on trainers only.

Absolutely, but we do recommend locking out front and rear suspension if you have the ability to.

The main benefit of a trainer tire over an inexpensive generic tire is that it's durable and able to provide the resistance curve for your trainer. Some tires have much higher or lower rolling resistance, and trainer tires will give the speed-resistance relationship that the trainer was designed for.

From a durability standpoint, it's not always easy to know which tires will be durable on a trainer before trying them.If you aren't sure what materials and manufacturing process were used to make your tire, then using a trainer tire is a good way to make sure the tire you use doesn’t wear out quickly after its purchase.

Additionally, old road tires often have grit embedded in the tread which can cause wear on the roller and make the tires slip and wear out quickly.If you're using old road tires on a trainer, it’s best to clean them and make sure to pick out all of the little pieces of dirt, stone, and glass that are embedded in the rubber before riding.

As of this posting, there appears to be an issue with Zwift that is causing the rolldown calibration of a Hammer or Magnus to fail. This is not an issue with your Hammer or Magnus trainer. Zwift is hard at work to resolve this.

Until a fix has been completed, we recommend that a rolldown calibration be done using the Rouvy software (no subscription required). There are support articles on Zwift and Rouvy to walk you through this process on Rouvy.

It is completely to fine to calibrate your trainer in Rouvy and then ride in Zwift because the calibration of the trainer is stored within the trainer; not the software.

The recommended calibration timing depends on which smart trainer you own. If you have a Hammer, a monthly calibration is all you need. If you own a Magnus, we recommend that you calibrate before each ride to ensure you’re receiving the very best data.

The 400 Pro, 420 and Phantom 5 indoor cycles will act as a progressive resistance trainer. The faster you pedal, the more difficult the resistance.

Additionally, there are three different resistance type to select between target power, target slope and gearing. To change resistance types press the joystick in. It is recommended that when doing a manual ride (i.e. not a preprogrammed workout), to stay in either target power or target slope and not switch between resistance types. When riding within target slope, be sure to change the gear.

This could be from an incorrect RU Sensor ID or the Joule display is not near the 400 Pro, 420 or Phantom 5 indoor cycle.

Make sure theindoor cycle is plugged in.

The 400 Pro, 420 or Phantom 5 indoor cycle uses a controlled resistance motor to help you target training (power or slope). Example if target watts is set to 100 and you speed up the resistance becomes much easier and if you slow down the resistance becomes much harder, because the motor is trying to keep you at that specific target power.

The yellow resistance knob doesn't move manually to adjust resistance because the resistance is adjusted electronically by the resistance button on the Joule 3.0. The resistance button is controlling an electronic motor in the down tube of the indoor cycle. On the 400 Pro, 420 or Phantom 5 indoor cycle the resistance knob only acts as an emergency brake.

Power Zones are simply ranges of wattage that you determine based on your lactate threshold (LT) value. Often, they are percentages of your LT value. Power Zones are used to control your training and gauge how hard you train. Consult a coach for more information for Power Zone training.

Due to external factors of riding a bike outside versus riding a solid indoor cycle, you may experience different values on your PowerTap. Also, with the special design of the flywheel, inertia plays much bigger role in your workout on the CycleOps indoor cycle versus riding your bike on the road. For instance, a larger effort is required to get your indoor cycle flywheel up to a certain speed, but due to inertia, the flywheel will spin much longer than a regular bicycle wheel, resulting in less work being required to maintain that predesigned speed.

The CycleOps indoor cycles are a standalone unit. They cannot be wired to other third party virtual reality software.

First be sure to double-check all electrical connections are properly attached (hub batteries, cadence and/or speed sensor batteries).

CycleOps PowerTap utilizes the ANT+ technology to ensure a robust and reliable connection between the various sensors used in our products. However, there is a limit to the number of sensors that can operate in a given environment. Practically speaking, when riding by yourself or with others using less than 30 total ANT+ sensor, you should see no more than 1% loss in data due to communication errors in your sensors. However, in an environment with more than 30 total ANT+ sensors you may see an increase in communication errors.

On the previous home models the perception of our speed was a bit high. We changed the settings in later models to make the speed more accurately feel like that of a road ride. Cadence was calculated more accurately based on gear ratio as well. Make sure you have the latest version of firmware.

Make sure you have a CycleOps indoor cycle model with a PowerTap. If there is not a PowerTap in the flywheel you will not have watts. Verify the correct power ID is learned into the display.

The display needs to be 'woken up' in order to operate. To wake up the display, simply press any button on the display (note: pressing a joystick will not wake the display).

If you have the resistance knob turned all the way to full resistance, and you still feel like you need more resistance, you should check the brake pads for alignment and wear. On the 300 PT & 200 E you may check to see if your cables have stretched. If the cables have stretched, you are not utilizing the full range of resistance available. You may also adjust the tension using the quick adjust barrel located at the rear brakes. You may check (on the previous club and current Pro Series models) to see if the brake pad needs to be adjusted. Loose the bolts and adjust the brake pad accordingly. Reference the User Guide.

The previous club models have a proprietary CycleOps USB stick that allows users to have their specific information saved onto the USB stick (heart rate and zones). The current Pro Series models work with Joule 3.0 and need the Multi User Accessory kit and allow for any off the shelf USB stick.

The height range is 4 feet 11 inches to 6 feet 6 inches. The height range is an approximate as inseam plays are large role in the fit of the indoor cycle. CycleOps offers two seat options. Contact Customer Service for options. The weight limit is 300 pounds (rider and bike combined).

The CycleOps indoor cycle flywheel weighs 48 pounds. The CycleOps indoor cycles were designed to make the unit ride and look like an actual outdoor bike. By moving the flywheel to the rear, we were able to more closely mimic not only the look of a real bike but also the feel. Finally, by locating the flywheel in the rear of the indoor cycle, we were able to keep it out of the "sweat zone"and thereby avoid contamination from sweat, leading to a longer life of the flywheel and resistance brake pad.

It is recommended that you wipe down the CycleOps indoor cycles down after each use. Do not us any harsh cleaners or chemicals. Avoid spraying any cleaners directly onto the CycleOps indoor cycles.

CycleOps indoor cycles are 48 inches x 13 inches x 34 inches (length x width x height). They weigh 140 pounds.

Currently all CycleOps indoor cycle models come with a 170mm crank arm length and a Q factor of 168mm (outside to outside). At this time, the 170mm crank arms are the only lengths available.

Yes, the CycleOps indoor cycle was designed to allow you to recreate your outdoor ride a closely as possible. To achieve this the Indoor Cycle will work with any standard bike saddle and pedals with 9/16 or 1/2 threading.

Occasionally, a rattling noise may come from the drive train of the indoor cycle. This is usually caused by incorrect chain tension. A chain that is too loose or too tight can cause noise. If you are unfamiliar with the adjustment protocol for bicycle drive trains, consult your local Authorized CycleOps Indoor Cycle Dealer to have your indoor cycle serviced.

The CycleOps indoor cycles have items on them that will need to be maintained, just like an outdoor bike. Things like: the brake pads, cables, chain, etc need to be maintained. Over time, the chain will stretch and need to be tightened in order to maximize the life of the cog as well as the chain. The chain will also need to be lubed monthly with a spray-type Teflon-based lubricant. CycleOps sells appropriate lubricant. Contact Customer Service for placing an order for part number 18087. The brake pads will wear down over time and will need to be replaced. Your local Authorized CycleOps Indoor Cycle Dealer can make all repairs.

Be sure all leveling feet on the underside of the bike are touching the ground. If the locking nuts have not been tightened, the feet could inadvertently thread up into the stabilizer, resulting in a foot that is not touching the ground.

No. Each flywheel must go through a stringent quality control checklist before it is installed on all CycleOps indoor cycles. You might experience some wobble due to the design of the PowerTap equipped flywheels. They require that all the parts be threaded onto the axle. Sometimes, if a part is not threaded perfectly, you will witness a small amount of "runout". More often than not, the flywheel may have shifted in shipping and just needs to be properly aligned in the dropouts. Contact your local Authorized CycleOps Indoor Cycle Dealer.
