There's a ton of talk right now about motor gear units (MGUs) coming out of Eurobike, but we haven't found content with enough depth to satisfy our questions. So in this episode, Dane and Josh go deep on MGUs, comparing five major players — Gobao, Avinox, Pinion, Owuru, and IntraDrive — and explaining how the different types of MGUs (stepped gearbox, CVT, and eCVT) actually work.

The guys cover both sides of the MGU topic in detail, and argue over a few points along the way. On the positive side, they may: be way easier to maintain, facilitate better battery range, offer wider gear ranges than cassettes, allow shifting anytime, and move weight toward the center of the bike (lowering the center of gravity and moving mass from unsprung to sprung - which could mean better suspension performance). On the negative side, they may have: extra pedal drag, a wider Q factor (think pedal strikes), and real uncertainty about repair/replacement when the whole drivetrain is one sealed unit. 

If you want the real detailed MGU breakdown behind the Eurobike headlines, not just another "derailleur is dead" hot take, this episode delivers it.
