RS5000 repair Stand

Full spec lightweight alloy workstand

RS-5000 is a full spec bike maintenance stand that allows you to reach anywhere you need to access while lifting up the bike.
Setting up is quite easy. Open the folded V-shape legs, extend the pillar, and raise up the clamp jaws. That's all.

Bike will be clamped at seat-post or top-tube by the clamp jaws, and the jaws are angle adjustable to hold the bike at your favorite angle.
Clamp height is fully adjustable between 940 and 1,510 mm from ground.

RS-5000 is mostly made of light alloy to be anti-rust, lightweight and compactly foldable for easy transportation. Folding and opening can be done quickly by the quick release levers. It doesn't require any tool.

The jaws can open to clamp up to 65 mm diameter tube, and open/shut the jaws and micro-adjustment can be done via just one lever.

The optional Tool Tray will be installed on the mid section of the pillar to put the removed parts and tools.

About Body design

Collaboration with Boeing engineer

There are many copies of RS-5000's V-shape leg design in the market, but it was originally developed by Minoura and Boeing.

Tri-pod design is too wide and each leg is lifted up from the floor, so it is often impeditive and your leg may be caught when passing along. But V-shape leg design just lay flat on the floor and won't disturb you.
Also you can tread upon the leg when you need more stability.
There is no rear part of V-shape leg so you can set RS-5000 just next to a wall to save the working space.

RS-5000 places the bike in the center of the triangle that the legs make for good stability.
The pillar is slanted to avoid hitting the pedal while maintenance.

Open/close legs and pillar height adjustment are done quickly by the quick release levers.
For more compact storage, the clamp jaws is also foldable.

Clamp jaws

Convenient single lever operation

You can open/close and micro-adjust the clamp jaws with just one lever. It is the modified type to prevent from damaging your fragile carbon or super thin alloy frame.

Push down the lever, the jaws will open. Pull up the lever, the jaws will close.
While keeping this closed condition, turn the knob on the lever clockwise to tighten the jaws to clamp the frame.

The jaws can clamp the diameter up to 65 mm and can be rotated 360 degrees in every 15 degrees step. With these functions, you can hold the bike at your favorite height and angle for easier job.

The previous clamp jaws with small and black knob that was used on RS-4000 or older models had sometimes lost the connection between the lever and roll-nut if you had loosened the knob too much. It was difficult to re-assemble, but the current clamp jaws on RS-5000 has anti-removal mechanism to avoid such problem.

compatibility with carbon frame

Cautions when mounting carbon monocoque frame

Basically, RS-5000 has no problem to use on carbon monocoque frame and thin alloy tubing frame bikes. But you should be aware of the following points before use;

1. Keep correct clamping process

The clamp jaws mechanism on RS-5000 is different from the one on RS-4000 or older models. You need to shut the jaws first, then tighten the knob to finish clamping the bike.

On the old system, your process is;
1) Pre-adjust the clamp jaws opening precisely
2) Pull up the lever to close the jaws
3) Finally, jaws hold the bike firmly after the link plate is set beyond the virtual pivot point.
However, if you had set the jaws opening too tight, it will cause crashing the thin tube by its strong lever power. The new mechanism adopted on RS-5000 solves this problem.

The process on the new clamp system is;
1) Pre-adjust the clamp jaws opening wider than necessary
2) Pull up the lever to close the jaws
3) Finally, turn the knob on the lever clockwise to clamp the bike.
This can avoid tube crashing problem due to too strong lever power, and you can manually adjust the clamping power.

2. There are some areas where you should not clamp

Carbon monocoque frame design is different from ordinary steel or alloy frame; the top-tube is not straight and parallel. It's usually that the center part of tubing is smaller than the ends. This is for expecting maximum strength with lightest weight.

We believe it's a quite rare case that the clamping point may be shifted to different point from the original point due to the vibration or shocks during maintenance job. It means the clamping power could become weaker than original.
It could make some troubles like that the bike will suddenly slide off when you lift up the bike, or the bike will suddenly turn and hit your body. It's dangerous.
To avoid this kind of problem, you should clamp the narrowest center part of the top-tube.

In addition, carbon monocoque technique can easily have strange dimension frame like as rectangle or triangle rather than normal round dimension. But every clamp jaws on workstand cannot hold such frame stably.
If your seat-post dimension is round type, clamp it instead of frame for your safety.

Be sure that any aerodynamic shape seat-post cannot be clamped.

3. Do not clamp the cables

Not just the issue on RS-5000, if you have clamped the top-tube together with brake or shifting cables, it will cause scratching problem to your bike frame.
It can be one of the solutions to escape from this problem that you put the cables on the jaws, not clamping together, but it will cause another problem that you cannot maintain the cable tension adjustment properly.

The clamp jaws on RS-5000 has a 10mm width groove on both top and bottom. You should set the cables in this groove to avoid scratching problem.
Also, the jaws will not touch each other when clamping bike frame, so there is enough space between the jaws. You can align the cable to this area if the cables are located on side.

When you maintain the cable tension adjustment, you should not clamp the frame and just put the frame on the lower jaw. At this moment, be careful about balance.


There is another type of workstand which can solve above problems. RS-1600 holds the bike without clamping the frame, but holds the bike with the front fork end and bottom bracket.
RS-1600 cannot locate the bike at tall point or change the bike angle dramatically like RS-5000 does, but it is completely free from frame clamping.

optional tools tray

Swivel useful tool tray

The tool tray for RS-5000 is its own special model. There is no compatibility with any other workstand.
Tray frame is inserted into the holes on the mid pillar joint.

Tray is separated into 4 blocks that is convenient to organize the removed parts or tools.
There are totally 24 slots and holes around the tray to hook the tools.

The plastic tray is swivel on the steel frame side to side to allow you to adjust the position for easier approach.

Important Notices

* RS-5000 is a portable workstand so it's not good to use it for heavy-duty job such as tightening bottom bracket.
* Use on flat and level floor or ground. Using it on slanted condition may cause falling down problem.
* Fully open the legs. RS-5000 is designed to keep the correct angle and balance when the legs are fully opened.
* Make sure you tighten the quick levers. If loosened, the pillar may slide down suddenly when you put a bike on.
* Close the clamp jaws by pulling up the lever then tighten to knob for clamping. The cam power is much stronger than we imagine. If you clamp the jaws by just pulling up the lever, it may give damage to the bike frame, especially fragile carbon or thin alloy ones.
* Not suitable to keep the bike vertical due to the balance problem. Do not place the bike upper than clamping point.
