Six weights
The widest single-listing range in this family, and the reason to buy from
here rather than from a set.
A collection is rarely short of 10 kg plates. It is short of the step between
the loading that works and the one that does not — and this listing covers
1.25, 2.5, 5, 7.5, 10 and 15 kg.
1.25 kg is the smallest plate on this shelf, a figure one other listing
publishes too. A pair adds two and a half
kilograms to a bar, which is half the step most home collections can manage.
Thirty, or thirty-one
The bore is published as a range.
That is more useful than a single figure. Home bars vary, and a plate machined
for exactly 30.0 mm can bind on a 31 mm sleeve — stating that both work is a
tolerance, not a vagueness.
On this site these fit the Maxxiva at Ø 30/31 mm.
Cement in plastic
The core and the sheath, both named, with the floor given as the reason.
Cement is less dense than iron, so a cement plate of a given weight is thicker
and wider than a cast iron one. What it buys is quiet and a floor that survives
a dropped plate.
Three plates in this family are built this way. The other four are iron: one
under rubber, one with a hammered finish, and two that publish no coating at
all.
Left off the listing
The thickness or the outer diameter — for any of the six sizes.
Across a range this wide that is a real gap: it is exactly the listing where a
buyer would want to know how much sleeve a 15 kg plate uses against a 5 kg one.
Availability
From 40 € to 60 € across the German, French and Italian Amazon stores, on the one reading this page rests on.
The Spanish Amazon store was asking more than 1.6× the cheapest country. A gap that wide normally means stock shipped in rather than a seller on the ground, so that figure sits outside the range above.
The British Amazon catalogue lists the reference with nobody selling behind it.
The American Amazon store returned nothing at all, so the buy button there opens a search rather than an empty page.
These figures are what Keepa returned on the day this page was last written. Stock and prices move without notice.
