PANARACER PURPLE LITE TPU 700 × 23–32C Inner Tube – Presta 85 mm, Ultralight 36 g, Purple (TW723-32F85-PL)

PANARACER PURPLE LITE TPU 700 × 23–32C is an ultralight road bike inner tube crafted from modern thermoplastic polyurethane (TPU). Weighing just 36 grams, it offers significant weight savings compared to traditional butyl tubes, outstanding packability, and convenience for both enthusiast and competitive road cycling.

This version features an 85 mm Presta valve, making it ideally suited for road bikes with deep-section rims. Its compact design allows it to be easily packed away as a spare in a saddle bag or jersey pocket.

PURPLE LITE – Advanced TPU Technology

The PURPLE LITE inner tube utilizes thermoplastic polyurethane, combining light weight, elasticity, and durability.

Compared to conventional butyl tubes, it substantially reduces the rotating mass of your wheels. This is particularly valuable for cyclists looking to optimize bike weight without replacing tires or wheelsets.

The TPU material also packs down exceptionally small, taking up minimal space in transit.

Just 36 Grams

The main highlight of the PURPLE LITE is its exceptionally low weight.

A weight of only 36 g delivers a considerable weight advantage over standard butyl road tubes.

For comparison, Panaracer references a standard road tube weighing 114 g. PURPLE LITE lets you shed tens of grams from each wheel.

Reduced rotational weight provides a noticeable benefit during acceleration and aggressive riding.

85 mm Presta Valve for Deep-Section Rims

The tube comes equipped with an 85 mm Presta valve.

The extended valve length is well-suited for high-profile aero rims where standard shorter valves cannot offer sufficient clearance for pump head attachment.

Always verify valve length compatibility with your specific rims before purchasing.

The valve features a two-piece construction consisting of a polymer base and a metal tip.

The metallic section enhances resistance to heat generated by portable electric tire inflators.

Securing Locknut and Spacer Washer

The valve design includes a locknut and spacer washer.

These components keep the valve securely centered in the rim hole, reducing movement and preventing annoying rattles while riding.

The locknut also makes it easier to seat pump heads securely when inflating.

Compact Dimensions for Easy Transport

TPU allows the tube to fold into a remarkably small package.

As a result, it easily fits into a saddle bag, jersey pocket, or frame storage box.

This makes the PURPLE LITE ideal not only as your primary performance inner tube, but also as a lightweight, space-saving spare on long rides and race days.

Compatibility with 700 × 23–32C Tires

This tube is engineered for road tires ranging from 700 × 23C to 700 × 32C.

It is compatible with 622 mm (700C / 28") rim diameters and tire widths between 23 and 32 mm.

Suitable tire sizes include 700 × 23C, 700 × 25C, 700 × 28C, 700 × 30C, and 700 × 32C.

Always adhere to the manufacturer-specified tire dimension range.

Installation Guidelines for TPU Tubes

TPU inner tubes require more careful handling than standard butyl tubes.

During installation, ensure the tube does not get pinched between the tire bead and the rim, and follow the manufacturer's guidance closely.

When inflating outside the tire, pressure must remain below 35 kPa (0.35 bar / 5 psi). Full operating pressure should only be applied once the tube is completely mounted inside the tire.

The manufacturer also notes that this inner tube is not intended to be repaired in the event of a puncture.
