Fincci Conna 700x25C folding, pair

Fincci’s pack is the most fully specified road tire on this shelf, and it is sold in the quantity people actually need.

What the manufacturer publishes

A black Conna tire in 700x25c with ETRTO 25-622, supplied as a two-pack. Each tire weighs 7.1 oz (200 g) with a TPI of 120, balancing weight and durability. A 1 mm (0.04 in) protection layer. Construction in nylon and rubber compound with a Kevlar bead for reinforcement. A tread described as offering good traction, suited to city and racing use.

Why publishing the protection thickness matters

Every tire manufacturer names its protection belt — V-Guard, K-Guard, GatorSkin — and none of those names tell you anything comparable. A millimeter figure does. It is not the whole story, since material and construction matter too, but it is a number rather than a trademark.

The 120 TPI position

Between the supple 180 TPI casings and the tough 60 TPI ones. For a training tire carrying a protection layer, that is the sensible place to be — a very supple casing under an armored tread is a contradiction.

Two hundred grams

Light for a protected tire. For comparison, a heavily armored commuting tire in this size is often 300 to 400 g (10.6 to 14.1 oz).

The pair

Tires wear at different rates — the rear far faster — but replacing both at once means matched grip front and rear, which is what you want when the road is wet.
