RIM DRIVE
Rim drive system is Minoura's world patent. The only
one solution for MTB's knobby tire.
The resistance unit is driven by the rubber roller touching
the rim side wall via a V-belt.
The rollers are pushed strongly toward the rim by internal
springs to avoid slippage, so any width of rim can be
used.
Good:
• Never touch the tire, so any type of tire can
be used without replacing
• Good for knobby tire or roughly tread patterned
tire
• Also good for road racers for warming-up &
cooling-down without worrying about expensive tire
Bad:
• Some slippage must occur between roller and
rim due to less friction
• Less natural pedal feel because the virtual
wheel diameter is smaller than tire drive
• Disc brake specialized rim with slanted side
wall design cannot be used on the current system
