Universal BB's would be smart . And fuck Nigel Sylvester !
In terms of parts maybe tires that use a more durable compound , like something motorcycles use ( not exactly , but along that line ) . Just so they last longer , and I save money ! Same with grips too , thin ones feel amazing by get ripped fast unless made my ODI
More thin pedals WITH knurling , it seems a lot of pedals now don't have it and I find personally find it very beneficial .
I think most frames now should have a 5mm dropout as a STANDARD . For example the new Volume Voyager has 4mm dropouts so I commented on the video asking why , and they basically said they're strong enough . But people like WTP and Stranger make 7-8mm dropouts , literally double the size . If 4mm is "strong" enough , why not just make it 5 so it's even better ? Like Billy Perry does fucked up grind combos , I think he'd agree that it should be a bit thicker
