Deal near Yishun MRT.

B30 was designed to make the bike lighter: no cups, threading, or redundant metal, plus a lighter, stiffer crank. That’s why the crank spindle is 30mm, which was a big jump up from narrow square-taper spindles.

There are two widths, road=68mm, MTB=73mm. Specify so we can provide the proper grease.

There are three grades of grease. TT and Track, All Round, and LongLife. The first is the least drag, the last is the most durable. All Round comes in road bearings, LongLife in MTB. Change the grease to tune performance.

CeramicSpeed standard bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. That’s thanks to balls that are 100% smoother and 15% harder than the ceramic competition. The bearings last at least three times longer than other bearings.
