What they say: Dimension Nack is at the cutting edge of Prologo’s vision, making it the most advanced and anatomically comfortable saddle ever.
What we say: At 245 mm long it’s around 30 mm shorter than most, making it part of the new generation of shorter-nosed saddles. This feature saves weight and gives more room when climbing aggressively, with the result that the Dimension weighs just 160 g.
The Nack part of the name signifies the braided monocoque carbon rails that measure 7 mm wide by 9.3 mm high. Available in 143 mm width only, the central hole is quite prominent and the top relatively flat in cross-section.
Conclusion: As cutting edge as they come in terms of design and construction.
