Co-op Cycles ADV 2.1 Tires: Separate Wire Beads from Tubeless-Ready Rims

Co-op Cycles ADV 2.1 tires and rims carry different descriptions in the saved item 254161 specification. Kenda Piedmont wire-bead tires accompany tubeless-ready WTB rims. Reading the rim label alone therefore cannot establish that the complete bicycle was supplied as a tubeless system or that its listed tires have tubeless approval.

Identify the Co-op Cycles ADV 2.1 tires first

The tire row names Kenda Piedmont, 700c x 45 mm, 30 tpi and wire bead. The separate Tire Width field also says 45 millimeters. Those are the published identifiers to retain when asking what was originally specified. A tire fitted by a later owner needs its own markings recorded.

Wire bead is the source's construction description. This entry does not add an express tubeless-ready statement to that tire. Avoid importing such approval from the adjacent wheel information or from a different tire sharing the same nominal width.

Rim readiness is a separate entry

REI lists WTB ST i21 TCS 2.0 rims, 29 in./700c, thirty-two holes and tubeless-ready. The features likewise describe tubeless-ready double-wall rims for riders considering an upgrade. Neither passage inventories installed tape, valves or sealant, and this reference supplies no conversion procedure.

If a used bicycle is advertised as tubeless, ask which actual tire and rim combination it now uses and what documentation applies. The original table can identify a starting wheel record; it cannot inspect an altered assembly merely because the bicycle still has an ADV badge.

Keep the fender condition with the clearance number

The saved features say tires up to 45 mm wide fit with fenders, which are not included. The fork row also retains the with-fender qualification. That is not a published maximum for every bare-frame tire arrangement or a measurement of an inflated replacement tire. Preserve the condition rather than quoting only the number.

The yellow historical photograph is family context, without a verified tire size. The Co-op range guide and brand topic help locate the right model before a wheel enquiry.

FAQ

Does the tire entry say tubeless ready?

No. It lists wire bead without that additional approval.

Are the rims described as tubeless ready?

Yes. That description belongs specifically to the WTB rim record.

Does 45 mm omit the fender condition?

No. The cited clearance statement explicitly includes that condition.
