M80-R minoura trainer new 2010

M80-R minoura trainer new 2010

High performance new basic series

M-series is the light-duty magnetic tire drive trainer line mainly for daily exercise. M80-R is the top model in the new M-series with a machined 0.8 kgs flywheel.

New M-series has the newly designed U-shape frame. It's made of 38mm diameter steel round tubing to be clean, simple, lightweight but enough durable to support the bike stiffly.

M80-R features a convenient quick release type hub clamping system that allows you to mount/dismount the bike very quickly. Just pushing down or pulling up the lever then the right side coupling slides to engage/release the acorn nut of the rear hub. You can save the setting up time and it becomes much easier to take the bike to outside after workout.

The Eddy Current magnetic unit generates great resistance to allow you full-fledged training. The maximum power at 40 km/h is 440 watts. It's very close to our top-end GYRO series power.

The flywheel is made of machined steel, not just a steel disc like M70 or M60, so it spins very smoothly without any vibration for makeing your pedaling comfortable and natural.

The resistance level can be adjusted from 7 levels via a handlebar or stem mounted remote shifter device. You don't need to stop pedaling and get off the bike to change the resistance level. It allows you to train with various patterns easily.

Features on M80-R

* Newly designed U-shaped frame
* Quick type hub clamping system
* 29mm diameter legs
* 0.8 kgs machined flywheel
* Transparent flywheel cover
* 7 levels resistance
* Oversize handlebar compatible remote shifter
eddy current system
Quiet and controllable magnetic resistance system

We Minoura is the pioneer of magnetic resistance system on indoor bike trainers.
At that time, there were only two ways to generate resistance; Wind fan and Roller pressure.
Fan type was really loud even though its exponential power curve was very realistic. Roller type was very short life and uncontrollable.
Our patented system was really welcomed to the people in '80s who wanted quiet and smooth resistance system.

The basic mechanism of Eddy Current System is simple.
There are two magnets facing each other, and an alloy disc is located between the magnets.
The magnets pulls or pushes each other depends on the sitting position. N–N or S–S pushes, and S–N pulls. Lines of magnetic force get stronger when the magnets pull each other. At this time, the alloy rotor cuts the lines then generates the resistance power.

One side magnet is fixed on the housing and another magnet can be rotated. By this mechanism, the resistance level can be easily controlled from low to high by changing the angle of the movable magnet.

The current unit has almost same mechanism, but each parts has been tuned up to improve the quality.
magnetic V.S fluid
If you want resistance control, Mag is the best choice

Fluid system was originally developed by CycleOps. Its mechanism is quite simple.
A turbine with fins spins in the chamber, and some liquid (fluid) are filled in the chamber. This system gets the power when the fan blade comes through the fluid.

Fluid system needs to be fully sealed in order to avoid fluid leakage, so it should be quiet but some poor quality models are loud.
The disadvantages on fluid system are 1) Oil may leak and 2) Resistance control is almost impossible.

The basic mechanism how to adjust the resistance power on fluid system is just changing the fluid level by moving the chamber's side wall. If the blades sink in the fluid deeper, the resistance should be greater.
However, in the real world, the fluid will not stay in the chamber as a pool once the turbine starts spin. All fluid will move to outer edge of the chamber like a ring, and the blades just touch the fluid even if the level is changed.
If they add more oil in the chamber to solve this problem, they will have to face oil leakage problem. As it is easily understandable, any churned liquid will have to intumesce due to the heat. It will increase the inside air pressure then finally the oil will start leaking. So they are not allowed to fill so much oil in the chamber.

As the result, the total range of resistance control on fluid system is much poorer than magnetic system.
remote shifter device
Convenient device to control the resistance level

The remote shifter allows you to adjust the resistance level during training without getting off the bike. It is a highly recommended feature for making your training as effective as possible to simulate various patterns of training easily.
Adjusting resistance may be able to be done by shifting gears on bike, but it is different from your desired condition that you want to train in your favorite gear combination. And also too wide gear ratio often makes pedaling jerky due to too much pedaling torque difference.

The clamp band is constructed with two parts; clamp band arm and removable shim. The shim is installed on each arm.
By putting the shims on or off to/from the arm, you can adjust the inner diameter to fit any size of handlebar including oversized one and also round dimension stem (square dimension stem is not compatible).

You can choose the resistance level from wide 7 positions by simply twisting the lever.
New U-shaped main frame
Lightweight new steel frame

M80-R adopts the newly designed U-shaped main frame. It is the lightest frame in our line for easier transportation.
It is made of simple 38mm diameter round tubing but the durability is strong enough to support up to 120 kgs weight (including bike weight).

The frame fits up to 700x40c.

When using 26x1.5" or smaller tire, you must install the supplied Z-shaped adaptor between the Mag unit and the base plate. The minimum wheel size is 24".
Quick hub clamping system
For minimizing your bike installation/removal time

We adopted a thread type hub clamping system on trainers for long time. The large handle helps the operation so it is not so difficult, but it has to take longer time than quick release system when you install or remove the bike on/from the trainer.
And also you must keep holding the bike with another hand during this job.

New M-series adopts the long-awaited quick hub clamping system on the right side (rear cog side). Just pushing down the lever, the coupling slides inward to catch the hub acorn in a second. You can release the bike from the trainer with just pulling up the lever.

The adjustment of coupling distance is done on the left side coupling. It is made of very durable single-piece solid bolt, and it has a lock ring to fix its position.

Please Note:
New M-series's coupling design is compatible with the supplied quick release skewer only. Any other skewers will not fit our coupling design.
When using the bike with plain nut type hub axle, you will not use the supplied skewer.

M80-R fits the rear hub width from 120mm to 145mm
Important Notice

* Mag resistance unit may become HOT while workout. Do NOT touch it during and at least for 15 minutes after finishing session.
* The rear wheel spins very fast and will cause serious injury if touch them. Keep children and pets away from trainer while using.
* The maximum load of M80-R is 120 kgs including bike weight.
* The couplings fit the supplied quick release skewer only. You cannot use your own skewer on Minoura trainer. You must replace the skewer before use.
* Hub nut type bike should have fitting problem. The inner diameter on coupling is larger than the standard hub nut so we cannot guarantee the stability. Replace the left side coupling to the optional special one.
* Any bike with internal transmission type hub cannot be used.
* M80-R does NOT have the Foot-Step. It's the normal knob bolt style.
