Cheer, Since moving to Brockley, I realised there's lots of untapped hill that is ripe to explore.
My colleague gonna give me his old wheel with a fixed/fixed hubs to give me two ratios (64GI and 61GI), almost came to a full stop on Fox Hill with 67GI.
Very useful!
You could add Taymount Rise and Grassmount with almost no extra distance.
