This section collects the options we stock, with the specification details that decide whether a part will work on a given bike listed on each product page rather than buried in a manual.
Axle compatibility, maximum wattage and the protocol used to connect to training software are listed. Where a listing covers several variants, the differences are stated in the title and the attribute table so the correct one can be selected before ordering.
Stock is held in the United States. Orders over $39 ship free, tracking is emailed as soon as the parcel is scanned, and unused items in original packaging can be returned within 30 days.
