Bottom bracket for DUB cranks in 42 mm bore BB30 shells (bearings seat in the frame via cups). sram.com shows an MSRP range of $45 to $290 (two offers: standard and ceramic bearings); list_price_usd is the low end, the standard bearing version. SRAM's road map also names a BB30 73-A version for asymmetric Cannondale shells. DUB spindles are 28.99 mm. SRAM states that DUB MTB Wide and Road Wide cranks use the same bottom bracket with wider spacers, so there is no separate DUB Wide bottom bracket. First year left null: the earliest SRAM document found that references DUB bottom bracket parts is the 2019 spare parts catalog (DUB spacer and preload kits), and no first party launch date was reached.
