Inputs

First: Wheel information

Data entry: in mm

Wheel diameter (in)

Wheel mass (g)

Arbor + adapter + ring mass (g)

Everything that spins that isn't the wheel: BS-8 arbor, Sopko adapter, balancing ring, screws. Weigh once, reuse.

✓ Flip Checked!

Second: Use TTB Method and report

Read every hole at the 12-o'clock (top) position.

Light-side hole — at 12 o'clock when the wheel rests

Let the wheel settle. The light side floats to the top; read the hole at 12 o'clock. This tells the tool which end of the axis is light — a rough read is fine.

TTB reversal holes — at 12 o'clock at each reversal

Set the wheel rocking. At each reversal (the instant it stops and reverses), read the hole at 12 o'clock — one per side. These fix the balance axis precisely.

TTB Period (s) TTB Goal (s)

Goal: period > 25 s. Goal range 25–60 s; higher is a tighter balance.

Results

Ring map

Setscrew & logo at top (light side). Hole 0 opposite, at bottom. Filled holes are colored by screw type. The arrow points to the light side — where correction weight goes — and its length shows the residual imbalance (g·in).

Prescription

Fill in the wheel, the reversal holes, the light-side hole, and the period — then calculate.

Flip Check

Before balancing, confirm the ring can actually pull the wheel into balance. This is the Flip Test: a quick, measurement-free go/no-go check.

1 · Wheel at rest — light side up

Properly mount the wheel on the hub, if not already done. If you are mounting a wheel onto the hub just prior to this test, it is recommended that you true the wheel on your grinder first. This removes any gross concentricity errors from the manufacturing process. Insert the arbor, place on the balancing stand, and let it settle to find the light side at 12-o'clock. Mark the light side with a pencil mark on the side. Mount the B-200 Balancing Ring on the hub with the logo and the mounting screw aligned with the light-side mark. Replace the wheel onto the balancing stand. If it flips, you're successful. If not, continue.

2 · Still no flip? Load the light side

If the ring alone didn't flip it, fill the six holes nearest the top — E, F, G, 5, 6, 7 — with your heaviest available screws, split around the mounting screw. This piles correction weight onto the light side.

If the wheel does NOT flip, change the ring mounting screws from a setscrew to a socket-head cap screw (SHCS). This adds more weight, and is a last-ditch effort to show that you are able to balance this wheel. If you have not trued the wheel yet, that may also be a problem.

If the wheel now flips — the light side swings down to become the new heavy side — the correction you can apply brackets the correction you need. You're within the ring's range. Remove the screws you added for this test. Proceed to balancing.

Did the wheel flip?

Try truing your wheel first, then return for the balancing process. Make sure the truing pass gets 100% coverage.

M = mounting setscrew (top, 12 o'clock) — reading position only, never a weight station. Mark the holes you fill. 15 weight holes at 22.5° spacing, bolt circle R0.950″.

Reading convention — Read every hole at the 12-o'clock (top) position. At rest the light side floats to the top: that hole is the light-side reading. Set the wheel rocking; at each reversal (the instant it stops and reverses) read the hole at 12 o'clock — one per side. Install the prescribed screws, run TTB again, and record the new period. Repeat until the period clears the goal.
