State Bicycle Co. 4130 Road v2 Tires: Keep the Stock 38mm Label Separate from the Suggested Maximum
State Bicycle Co. 4130 Road v2 tires have a stock 700 x 38c label and a separate suggested maximum of 40mm in the PDF. These are different statements. The first identifies the documented tyre package; the second does not measure the clearance or installed tyre width on a particular bicycle.
Read the State Bicycle Co. 4130 Road v2 tires by name
The product page names CST Metropolitan Escape, 700 x 38c. Retain the complete model name alongside the size when checking what a bicycle is wearing. A generic “700c tyre” description discards information that the manufacturer actually supplies, while an owner’s replacement may need its own markings recorded.
The PDF overview includes Presta valve wording with the 700 x 38c entry. Keep that detail attached to this published tyre and tube record. It does not establish every valve arrangement, tube choice or replacement wheel that could be used on another generation or a modified bicycle.
Separate the stock label from the suggested maximum
The PDF’s detailed tyre section names the same CST model and lists “Suggested Max Tire: 40mm”. Preserve the word suggested and the scope of that document. It is not a measurement of an inflated tyre and does not state a mudguard allowance, clearance under every riding condition or approval for an unnamed alternative tyre.
The existing Black & Tan Road v2 listing gives a specific bicycle identity to pair with this reference. Its catalogue title should not be shortened to a generic State 4130 when checking a tyre question. The catalogue listing is State Bicycle Co. 4130 Road v2 - Black & Tan - (8-Speed).
Keep the wheel measurements out of the tyre-width field
The wheel entries describe a 700c aluminum wheelset and a double-wall 27mm height record. The product specification describes the rim’s 27mm depth. That figure is separate from the tyre’s 38mm size label and should not replace it in a comparison note. No additional rim-width measurement is invented here.
For a wider-tyre enquiry, supply the actual bicycle identity, fitted tyre and intended change, then have the remaining match confirmed. This specification alone offers no tyre-pressure prescription or tubeless approval. The photograph shows a historical Contender owner build, so its visible tyres cannot establish Road v2 clearance.
Use the existing State introduction for family background alongside these tyre-specific entries. State Bicycle Co. topic; existing State introduction.
