Master 25 SPS


Master 25 SPS open tubulars are designed for bicycle training and racing.

They are lightweight (220 gr) and suitable for any kind of purpose to offer greater performance than a clincher tire and this is why we call them ‘open tubulars’.


Master 25 SPS open tubulars have a 25 mm section that provides an extraordinary combination of comfort and performance.

Master 25 SPS are made with the same 320 TPI (thread per inch) casing as Veloflex tubulars to offer lower rolling resistance and greater flexibility.

Master 25 SPS tubulars 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 suitable 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 during 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 SPS open bicycle tubulars are handmade in Italy with artisan processing and in limited quantity.
