About this deal

Your wheels are only as good as your bicycle inner tubes, so it’s good advice to get the best you can afford.

Forgiato e ottimizzato nella forma con macchinario CNC per garantire leggerezza (-30% rispetto alle MAD-Tecno). L'incrocio dei raggi permette di gestire in modo piú performante la torsione dovuta alla frenata che viene trasmessa dal mozzo al cerchio.

A Schrader valve bike pump, for instance, contains a pin in the pump head to be inserted onto the check valve. It is best broadly speaking, to stick to manufacturers recommended guidelines to get the best performance. As an alternative to butyl, there are latex inner tubes, that are more elastic, significantly plus there’s less friction against the tyre, resulting in lower rolling resistance. Schrader valves have a diameter of , larger than Presta valves which are 6 mm: normally air guns and compressors have a connection compatible with Schrader valves but not with Presta.

The former are the most common, have a normalized thickness and are used on a myriad of wheels of different diameters and widths. The Presta was developed for the high pressures that are usually used on racing bikes (10 bar 145 PSI), are a little more awkward to use and not necessary for the pressures used on the unicycle. Un'ultima considerazione va fatta sul concetto componenti da gara, l'alluminio utilizzato (Ergal 7075) ha delle caratteristiche meccaniche che permettono di realizzare in sicurezza pezzi piuttosto leggeri.We're constantly expanding our ranges to help as many riders as possible and if you can't find what you're looking for, please get in touch, we'd love to hear from you and hopefully we can get what you need (or we may already have it! Il prezzo comprende già le migliori scelte in ambito mozzo (Mad4One Disc ISIS), pedivelle (ISIS MAD-Tecno 2 fori), cerchio (rinforzato) e pneumatico, ma il telaio è quello degli URC, fatto in lega di acciaio al cromo molibdeno Cr-Mo-4130, la migliore lega in acciaio oggi disponibile, che garantisce una maggiore resistenza al carico, un peso specifico inferiore e una migliore resistenza alla trazione rispetto agli acciai comuni al carbonio.
