Product Details

Overview & Technology

Evo's Schrader 700x18-25C inner tube is built from a premium butyl rubber compound and engineered with a 0.85mm wall thickness to balance puncture resistance, airtightness and weight. The tube uses a 48mm non-threaded Schrader valve that fits standard pump heads and most aftermarket floor pumps without adaptors. The manufacturing process emphasizes uniform wall thickness and clean valve seating to reduce slow leaks and improve long-term pressure retention. Although not marked as thorn-resistant, the thicker 0.85mm construction gives added durability over ultra-light tubes, making it a dependable spare or everyday replacement for road riders.

Key Features

Designed for dependable road performance: • Wall thickness: 0.85mm butyl — a middle ground between lightweight and heavy-duty tubes for everyday road use. • Valve: 48mm Schrader (non-threaded shaft) — easy to inflate with most pumps and compatible with common presta adaptors for interim use. • Size compatibility: Optimized for 700x18-25C tires (ISO 630mm wheel diameter). • Lightweight packaging: Shipping weight 0.24 lb and compact dimensions for carrying a spare on rides or stocking in the shop. These features make the Evo Schrader tube a practical, no-fuss choice for riders who want a reliable tube that balances durability and weight.

Fit & Compatibility

The Evo Schrader tube is sized for 700C wheels and specifically fits 700x18–25C tires. For riders using 27" (ISO 630mm) tires the common conversions are: 700x18–25C = 27x1. The tube's 48mm Schrader valve suits most standard road rims and many mid-depth aerodynamic rims; if your rim is deep (>40–50mm) you should measure valve length requirements before purchase. Valve shaft is non-threaded, so it accepts push-on Schrader pump heads and universal floor pumps. It is not thorn-resistant—if you regularly ride rough, debris-strewn roads or gravel you may prefer a tube with added puncture protection or a tubeless setup.

Who It's For

This tube is ideal for recreational and commuter road cyclists, club riders, and shops needing a reliable, affordable spare. It suits riders who value durability and easy inflation over the last grams of weight savings offered by ultra-light tubes. Not recommended as a primary choice for competitive racers seeking maximum weight savings or for off-road/gravel riders who need reinforced thorn protection. For everyday road use and reliable roadside replacements, the Evo Schrader 700x18-25C is a practical go-to.

Frequently Asked Questions

What tires is this tube compatible with?

This Evo Schrader tube is sized for 700x18–25C tires on 700C (ISO 630mm) wheels. It also maps to the 27" conversion 700x18–25C = 27x1. Check your tire sidewall if you're unsure of the exact sizing.

Will the 48mm Schrader valve fit my rim?

A 48mm valve works with most standard road rims and many mid-depth rims. If you use deep-section aerodynamic rims (>40–50mm depth), confirm required valve length for a flush fit or choose a longer valve tube.

Is this tube puncture or thorn resistant?

No — this tube is not marketed as thorn-resistant. The 0.85mm butyl wall offers improved durability over ultra-light tubes but doesn't replace dedicated puncture-resistant or reinforced models.

Can I patch this tube if it gets a puncture?

Yes. The butyl construction is fully patchable using standard vulcanizing or self-adhesive patches. For larger cuts or damaged valve stems, replacement is recommended.

Will this valve work with my pump?

The non-threaded Schrader valve accepts push-on Schrader heads and all standard floor pumps. If your pump is Presta-only, you'll need a Presta-to-Schrader adaptor to use this tube.

How heavy is the tube and how compact is it to carry?

The shipment weight is about 0.24 lb and the package measures roughly 4" x 3" x 1.5", making it compact and easy to stow in a saddle bag or jersey pocket as a spare.

Buying Guide

When choosing an inner tube, match three things first: tube size (tire width and wheel diameter), valve type and valve length, and desired protection level. For typical road use, a butyl tube with 0.7–1.0mm wall thickness — like this Evo 0.85mm tube — offers a good compromise between weight and puncture resistance. If you run deep rims, measure rim depth to ensure the valve length is sufficient; for off-road or debris-prone routes, consider thorn-resistant models or a tubeless setup. Finally, choose a valve type (Presta vs Schrader) that matches your pump and rim valve hole — adaptors can bridge the gap but a correct valve length is harder to substitute.
