Master 23 SPS


Master 23 SPS open tubulars are designed for bicycle training and racing.

As they are extremely lightweight (only 205 gr) Master 23 SPS open tubulars are suitable for any kind of purpose and are able to offer greater performance than one would normally expect from an ordinary clincher tire. Thus, they are called ‘open tubulars’.

Master 23 SPS open tubular 23 mm section guarantees lower rolling resistance and unrivalled sprint for acceleration.

Master 23 SPS are made with the same 320 TPI (thread per inch) casing as Veloflex tubulars to offer lower rolling resistance and greater flexibility.

Master 23 SPS use SPS technology (Sidewall Protection System): a further sidewall protection system that makes the clincher tires suitable for all carbon rims available on the market, regardless of the type or brand.

They are perfect for training and racing as they combine the excellent performance of a tubular and the comfortable mounting and fitting of a clincher tire while guaranteeing great handling when cornering in all weather conditions.

All Master SPS tubular sidewalls have a unique gum colour, which gives them a classic look, and are made with superior material processed with the latest technology.

Like all Veloflex products, Master 23 SPS open bicycle tubulars are handmade with artisan processing and in limited quantity in Italy.
