CYCLAMI TPU 700C Inner Tube 2-Pack, 80mm Valve Removable Core, Ultra-Light 38 g

These CYCLAMI TPU inner tubes are built for riders who want a lightweight, compact spare without sacrificing airtight performance. Constructed from thermoplastic polyurethane (TPU), each tube weighs about 38 g and packs much smaller than standard butyl tubes, making them ideal for race days, training rides and on-the-road repairs. The removable metal Presta valve core (80 mm) lets you service or replace the core quickly, and the TPU material offers enhanced sealing and shock absorption compared with conventional inner tubes.

Which tyre sizes and valve specifications fit this tube?

These tubes are made for 700C road bike rims and accommodate a range of tyre widths from 18C up to 32C. They come with an 80 mm metal Presta valve and a removable valve core for easy maintenance.

• Compatible tyre sizes: 700 x 18C, 23C, 25C, 28C, 30C, 32C
• Valve type: Presta (metal) with removable core
• Valve length: 80 mm suitable for deep-section rims
• Pack: two tubes per set for quick replacement on the road

How does the removable valve core help me as a rider?

The removable core allows you to replace a damaged core without swapping the whole tube, and it simplifies adding sealant if you choose to use it. It also makes pumping faster by removing flow restriction during CO2 or hand-pump inflation.

• Replace a worn or bent core without changing the tube
• Easier and faster inflation with CO2 canisters or high-flow pumps
• Simplifies adding liquid sealant when desired
• Spare cores are commonly available and easy to install

What are the benefits of TPU material compared with butyl tubes?

TPU tubes are notably lighter and more compact while providing strong sealing and good shock absorption. They can reduce pack volume and weight substantially, which matters for racers and lightweight touring riders.

• Weight: approximately 38 g per tube — up to 70% lighter than butyl alternatives
• Space: about 50% less storage space in a saddle bag or jersey pocket
• Performance: improved airtight sealing and better vibration damping
• Durability: resilient TPU construction with good tear resistance under typical road use

How should I install, inflate and care for these CYCLAMI tubes?

Install with care to avoid pinching: lightly pre-inflate before tucking the tube into the tyre and keep the rim bed and tyre interior clean. Follow the recommended pre-inflation and tire pressure guidelines to reduce puncture risk.

• Pre-inflate to max 0.5 bar (8 psi) before installation to prevent twisting
• Ensure rim tape, rim bed and tyre interior are free of debris
• Seat the tyre bead fully before reaching riding pressure
• Check valve core seating; tighten the removable core if necessary

Who this is for: The CYCLAMI 2 Pack TPU 700C inner tubes suit road cyclists who prioritize low weight and compact spares — racers, climbers, light-pack commuters and weekend athletes who want a reliable, serviceable replacement tube. If you routinely use deep-section rims, carry minimal kit, or value fast CO2 inflation and easy valve servicing, these tubes are an efficient choice. For riders who prefer maximum puncture protection or run very wide tyres, consider whether TPU tubes meet your puncture-resistance preferences before purchase.
