Order GT Superlace BMX Hubs Race Cassette Hubset New Pair

GT Superlace BMX Hubs Pro 120 point cassette hub set, F/R 3/8″ female axles with thread in bolts, 36 hole F/R, Includes 16T chromoly cog, spacers and lock-ring. The 9T RSD driver sitting next to the hubs is also included. These same style retro GT hubs were sold back in the 1980s. GT started making these again in 2017.

NOTE: The outer flanges may have some tiny marks on it from the extra parts in the box rubbing on it. The spokes will mainly cover it up. We repackage so it wont keep happening. See image of the scratch/mark. Lately we see no marks.

Here is the hub Specs needed for determining spoke length with a online spoke length Calculator.

Front Hub in Millimeters

LCF 34.5
RCF 34.5

LFD 61
RFD 61

Rear Hub in Millimeters

LCF 25
RCF 27

LFD 56
RFD 56

Get your Rims ERD and use these specs in a spoke length calculator and you will have the spoke length needed. If your spokes are plus or minus 2 millimeters you will be OK as long as all the spokes are the same length.

The ERD on say a Sun Rhynolite rim is 395mm for one example. I typed in the dimensions with the online Spoke calculater with 3 cross lacing pattern and got 186mm for both hubs. This size is pretty common so it makes sense too! The most common mistake people make when building their own wheels is the spoke direction. You can see the mistake at the valve hole when the spokes to flow away from the hole making less room for the tube valve.
