Bottom brackets are like America’s waistline, they keep getting bigger and wider
@sgluckman showed up for Sunday’s Green River Killer ride with some new kit, an EVO BB with K-Force crank. I spotted the massive bearings and he said “…noticed the difference immediately. The bike is zoomier and responsive.” Like a set of fast wheels, EVO is a worthwhile upgrade to consider for your bike. Is it “yet another BB standard?” Sort of, I asked Mark and he replied
BB386EVO is like a BB30 crank with a wider spindle but same Q-factor. It’s a crank that fits BB30 (direct-fit or PressFit) frames with a spacer on each side, but it can also fit regular English-threaded BB with threaded external bearing BB cups. It’s one, light, stiff crank that’ll fit the majority of BB standards out there.
Standards in this industry amount to more than one manufacturer making something. When a mechanic asks if you measured your bars “center to center, inside to inside, or outside to outside,” you’ll know what I mean. EVO gets you a stiffer crank and fits your current bike. The next standard will come along after you’ve worn out the EVO chain rings and you can consider what to do then. For now, if you want a quicker bike, we recommend it. Ask your local bike shop about EVO and the cost. For more on EVO v. BB30, see this comment thread, where I ask Mark who are the assholes changing BB standards all the time?…
