T47 Bottom Bracket Dust Cover for 30mm Spindle

Bottom Bracket Type: T47

Recommended Material: ASA

Spindle Width: 30mm

I bought a T47 ceramic bottom bracket and the OEM dust covers were too wide for the 85.5mm-86.5mm bottom bracket shell. As a result when I tried to install the crankset without any spacers without adjusting any preload there was loads of friction. I created this dust cover based on the OEM dust cover that came with the ceramic BB, except these are 1mm shorter in width which results in 2mm shorter net when taking into account the left and right bottom bracket cups. After installing these, I was able to install the crankset without issue, I added a 1mm spacer on the spindle and was able to properly adjust pre-load from there. 

I have not tested this however this I BELIEVE should be able to work for a BB386 evo 30mm bottom bracket, as they are the same width shell, just one is pressfit while other is threaded.
