Minoura Japan – True-Pro Combo 2

Bike wheel is constructed with many spokes coming from the hub, and the nipples hold the spokes on the rim. Nipple has thread inside, and it will pull the spoke when it's turned.

Prior to wheel truing maintenance, you should check if each spoke tension is OK or not.
Loosened spoke tension will happen the wheel deformation again shortly, and too tight spoke tension will break the spoke if you get hard shock. The spoke tension is measured by a special spoke tension meter.

Next, rotate the wheel slowly (do not spin fast) and check the clearance between the rim surface and the gauge.
If the wheel has been deformed, you will see the clearance is not equal. Wheel truing means to make every clearance equal.

You should keep the basic theory to expect correct result;
1. Keep the correct spoke tension
2. Tighten the nipple coming from opposite side of shaking
(For example, if the rim shakes rightward than the center, you must tighten the nipple on the spoke coming from left side)
3. Do not loosen the nipple

For more detailed information about this maintenance, refer the guide books or ask to the skilled mechanic.

The bike wheel truing stand is usually constructed with two pillars to support wheel and a gauge to check shaking.
There is a single arm type truing stand available, but it's not good for beginners.

Cheap truing stand fixes either pillar to the base, and another pillar moves.
If you mount different hub width wheels on this stand, of course, the gauge position must be adjusted because the hub width (wheel center) is different.
So you must have a wheel dishing too to check the wheel left-right symmetry.

Both pillars on True Pro 2 move together to keep any wheel in the virtual center no matter what the hub width is. This will help you to have almost centered wheel even without dishing tool.
(CAUTION: We don't guarantee you can get exactly centered wheel by using TruePro2. To expect the proper symmetry, you must use dishing tool.)

The pillar top part which supports wheel axle is angle adjustable in order to fit any size of hub width as tightly as possible. If the wheel has been installed on the stand angled, you cannot expect any proper result.

True Pro 2 has a couple of gauge arms to check side shaking and a rod type gauge to check vertical shaking.

Turn the knob then both arms will open/close together. So you can do centering the wheel by just making both clearance equal.
Each arm can be opened widely and locked, so it's very easy to change the wheel even with tire (it's fatter than the rim only) while keeping the same rim width.

The vertical gauge is foldable so you can keep it away from the wheel when not in use.
Turn the middle ring then you can adjust the gauge length to face to the rim at ideal angle.

Even though TruePro2 holds the wheel correctly, if the gauge set has been sit in wrong position, you cannot expect any proper result. It's not funny that you were able to solve every shaking but the wheel is not symmetrical.

Check the gauge position prior to setting the wheel on stand.
T-Gauge 2 is much longer than the previous Tri-Gauge. This is for allowing you to check the gauge position at the exact position you do wheel truing.
Set T-Gauge2 on the stand and place the tip between the side shaking gauge arms. If both right and left side clearance are equal, it means the gauge is set in correct position. if not, adjust the gauge position by loosening the backside screws.

• SKU 430-3310-00
• Applicable Wheel Size up to 29-inch
• Applicable Hub Width 85 - 150 mm
• Dimensions L 470 x W 200 x D 70 mm (folded)
• Color Silver
• Material Steel (body) / Alloy (pillar)
• Net Weight 2.6 kgs (set)

• TruePro2 is just a portable wheel truing stand for ordinary people. The quality, stability and assuredness are lower than the professional model.
• We don't guarantee you can get precisely symmetrical wheel by using TruePro2 only. You must use the wheel dishing tool.
• Only for the wheels with 9mm quick release or hub nut type hubs. Any thru axle type hub is not compatible.
• When setting wheel on TruePro2, tighten the quick lever while pushing down the axle. If the wheel has been slanted, you cannot expect correct job. Especially when tightening the lever, be careful the wheel doesn't move.
• Rotate the wheel slowly to prevent vibration. It is meaningless if you spin fast.
• Use T-Gauge2 to check the gauge center position before use.
• Wheel is one of the most important parts on your safety as well as the brake. If you are not confident to do proper maintenance job or if you have limited skill only, you should ask to the skilled mechanics for the technique.
• Wheel truing must be done at your own risk. We won't be responsible to any result your job makes.
