Make sure the Steel Collar is inserted from outside on the left side frame,
!
but from inside on the right side frame, because both frames are common
and exactly same.
• The left and right side frame are exactly the same. The left side hole is always larger than the right
side one. The Steel Collar is inserted from the larger hole.
• Do not tighten the Cap Nut without the colllar, otherwise the alloy frame will have to be deformed.
• The nuts on both roller drum end work for holding the bearing in correct position. It's already precisely
adjusted in the factory. You don't need to maintain this nut basically.

Open the frame (don't straighten yet) to install the roller drums.
(see Fig. A)
The roller drum has no fixed direction. You can use any roller on
any position.
Remember the Steel Collar insertion direction is different on right
and left side frame as described above.
Measure the actual wheelbase (the distance between the front and
2
rear wheel axle) of your bike. Set the front drum at correct hole by
referring the wheelbase indicator on the front frame. (see Fig. B)
If you set the rear roller drum to the forward hole for 24"/650c sized wheel, the bike will move
20mm forward (a half of the hole distance). Please calculate the wheelbase size 20mm shorter
than the indicated numbers.
