New and discontinued wheels, by month
On the first day of each month we compare every wheel record on this site, and every Amazon listing we link to, against the previous check. A month is published only when at least two things changed. Every line comes from a wheel record or an Amazon listing.
No monthly update has been published yet. The catalogue is checked on the first day of each month, and the first update will appear here once at least two changes have been recorded. Meanwhile, the full wheel table is kept current.
