My bike Btwin fitness 1.
There was some play in my bottom bracket and I opened regreased and tightened it.
The brand is a Vp .
Thought I should install a shimano instead.
Following is the specification with images:
After checking the measurements with a scale and reading the sticker , i realised that the available shimano bb are of 68x 118, 68x122 and 68x 122.5.
Since i need a 68 x 120 , which size would be appropriate, I am unable to source the same size.
What does the BC 1.37x24T stand for ?
Should there be any other specifications that I need for a bottom bracket sizing.
