The Minoura LiveRoll R720 is a triple roller trainer designed for indoor cycling, offering a realistic and smooth riding experience. This trainer is specifically engineered for standard 2-wheel bicycles with a wheelbase between 950mm and 1,080mm. It is not suitable for tandems, recumbent bikes, folding bikes, or bikes outside the specified wheelbase range.
The primary function of the LiveRoll R720 is to allow cyclists to train indoors, simulating the feel of riding on the road. Unlike stationary trainers that fix the bike in place, roller trainers require the rider to maintain balance, thereby engaging core muscles and improving bike handling skills. The trainer features large 105mm diameter roller drums, which contribute to a super smooth and quiet ride.
The trainer's design incorporates a newly developed sliding frame system that simplifies the adjustment process for various wheel sizes. This system allows for quick and easy changes to accommodate different bikes within the specified wheelbase range. The frame can be shortened to a minimum size for compact storage and then quickly extended to the desired length using quick releases, making it convenient for users with limited space.
A key aspect of the LiveRoll R720's design is its specially arranged roller layout, which aims to provide a natural riding experience in a comfortable, level position. This setup helps riders maintain a stable and balanced posture throughout their training sessions. The trainer also includes a high-quality wooden foot step, which offers a safe and convenient area for riders to dismount or touch down when needed, especially for those who find reaching the floor difficult from their riding position.
For beginners or those new to roller training, the R720 comes with a Front Wheel Guard Kit. This accessory helps prevent the front wheel from coming off the roller, which can be a common challenge for new users as their front wheel tends to move side-to-side. Installing the guard provides an added layer of safety and confidence during the initial learning phase.
Setting up the LiveRoll R720 involves a few straightforward steps. The pre-assembled frame consists of a longer rear frame and a shorter front frame. The quick lever and nut are installed on the front hole of the long hole on the rear frame, allowing for length adjustment. It's crucial to ensure the quick lever is located on the outside. The frame should initially be shortened to its minimum size, and the quick release temporarily tightened without over-tightening.
Installing the roller drums begins with the left side frame. The drums are identical and symmetric, so there's no specific direction or position. An alloy sleeve is passed through the roller axle, with its narrower diameter end facing the frame. This narrower end must fit correctly into the frame hole. A flat washer, spring washer, and dome nut are then placed on the axle, though not tightened firmly at this stage. The roller belt is then installed onto both the middle and front rollers. The same process is repeated for the right side frame, ensuring the alloy sleeve direction is correct for all rollers. It's vital that all alloy sleeves are properly inserted into the frame holes to prevent damage when tightening the nuts later.
Once the rollers are installed, the R720 should be placed on a flat and level floor. The bottom side, with its rubber feet, should face the user, and the roller belt should be positioned at the back. An alloy bar is then installed between the frames using M6 bolts and spring washers, acting as a reinforcement. It's important not to pass the alloy bar through the roller belt, as this will impede the belt line and cause damage.
The final step in assembly involves tightening all dome nuts firmly. However, it's crucial not to over-tighten them, as this can cause serious damage to the frame, axle threads, and alloy sleeves. The recommended tightening torque is 10 N.m, which is lighter than one might expect.
The wooden foot step can be installed either on the inside or outside of the left side frame, depending on user preference. For installation on the inside, the step is placed over the frame with its legs facing inward, and the shorter legs are attached from the outside, with the bolt inserted and the nut tightened from the inside. For outside installation, the step legs face outward, and the shorter legs are attached from the frame's outside, with the bolt inserted and the nut tightened from the inside. When installing the foot step, it's essential to ensure the roller belt is on the opposite side of the step to avoid disturbing the belt line.
Adjusting the front roller position is critical for bike stability and overall performance. The R720 features a bracket in a long hole on each rear frame, which serves as a wheelbase setting gauge. By loosening the bolt (without removing it) and sliding the bracket to the desired wheelbase size indicated by its tip, the front roller can be precisely positioned. For instance, a 980mm wheelbase bike would require setting the indicator at "980," which positions the front roller 10mm ahead of the front wheel axle—an ideal setting for most riders. It's important to set both side indicators to the same position to prevent the front roller from being angled, which can make riding straight difficult. The available wheelbase range for the R720 is 950mm to 1,080mm. Bikes shorter than 950mm may have the front roller too far forward, affecting handling, while bikes longer than 1,080mm could cause the rider to fall off forward. The front roller position influences bike handling; a shorter distance makes handling quicker, suitable for advanced riders, while a longer distance can make handling sluggish.
Before use, the quick release levers need to be properly adjusted so that the front frame can be firmly fixed by simply bending the lever. This adjustment should be done while the frame is retracted, by precisely adjusting the backside nut until resistance is felt when the lever is horizontal. This process should be done on both sides. It's important to use only the nut for tightening, not the lever.
When extending the frame, ensure the roller belt is not resting on the frame to prevent it from getting caught. The front frame is pulled out until it reaches the stopper, and the quick release lever is then tightened firmly, directed towards the floor. The roller belt is then hooked into the grooves on the rollers. Rotating the rollers helps seat the belt properly, and care should be taken not to pinch fingers. It's not recommended to hook the roller belt before extending the front frame, as this requires holding the R720 by pressing the rear roller with a foot to prevent it from snapping back due to belt tension, which could cause injury. Firmly tightening the quick levers is crucial, as loose levers could cause the front frame to retract during rough riding, leading to a fall.
The LiveRoll R720 is designed for durability, but proper care ensures its longevity and optimal performance. Regular checks of the quick release levers are important to ensure they remain firmly tightened, preventing any unexpected retraction of the front frame during use.
The product comes with a 1-year limited warranty from the date of purchase for the original owner, provided it was purchased in brand-new condition from a Minoura authorized dealer. This warranty covers manufacturer's defects but does not extend to natural wear or other problems not caused by manufacturing flaws. Any strange noises or smells detected during use should prompt immediate cessation of exercise and consultation with the shop where the R720 was purchased. Users should not attempt to disassemble or modify the product without prior approval from Minoura.
It's recommended to use a mat between the rollers and the floor, as rubber roller parts and sweat can cause stains. This not only protects the floor but also helps maintain the cleanliness of the trainer.
For those with longer wheelbase bikes, such as 29ers, an optional "Long Slide Rail" (SKU: 400-3702-00) is available. This accessory allows for an extension of the wheelbase capacity by 100mm, changing the applicable wheelbase size from 950 – 1,080mm to 1,050 – 1,180mm. This feature enhances the trainer's versatility for a wider range of bicycles.
It's important to note that accessories designed for other Minoura rollers are not compatible with the R720. This includes other foot steps, front wheel guards, Mag units, or carrying bags, emphasizing the need to use only R720-specific accessories.
When transporting the trainer, care should be taken to avoid dropping, bumping, or otherwise abusing the frame, as this can cause damage. The frame's ability to break down into a compact package aids in safe storage and transport.
For any questions or requests, users are advised to refer to the supplied "Minoura Limited Warranty Policy" card and contact the original purchase shop or the distributor in their country. Contact information for Minoura North America and Minoura Japan is provided for customer support.
