PROLOGO DIMENSION NDR TIROX CPC

Railed it
Tirox is the name Prologo use for the titanium tubing employed on the Dimension. The Prologo rails’ shape and fixing points offer around a centimetre more fore-aft adjustment than the Specialized, which is to be expected, as at 245mm long the Dimension is 5mm longer than the Power Arc.
Down to hull
Prologo uses carbon fibre for its hull construction, the rail fittings on the Dimension are wider at the rear and the hull itself changes thickness, getting significantly thinner towards the central channel. The stepped-down nose has a box section underneath into which the rails are bonded. At the rear, Prologo uses its U-Clip system where you can add a mount point for a variety of accessories.
Padding around
The NDR in the name means this version comes with deeper high-density padding. It was developed for mountain bike cross-country world champion Manuel Fumic, but is aimed at on and off road.
Even with the extra padding, the 207.1g weight is suitably light. The P.A.S. channel is one of the best designs around – wide, wellshaped and running the full length of the saddle.
The real winner here is the CPC cover – the tiny volcanoshaped rubberised tubes offer incredible grip in the wet and give the surface a more fluid feel. In hot weather the separation from the saddle surface keeps you comfortable. The Dimension is only available in 143mm width, but if it fits your sit bones then we’d highly recommend it.
