RATIO road components – First look

Carbon and alloy road components from an industry veteran

RATIO are a new company started by Italian bike industry veteran Pancrazio Centola, who has previously worked for the likes of 3T and Deda Elementi. As well as some promising-looking carbon fibre road frames and forks, they’re launching a range of Taiwanese-made components and accessories, and we’ve been given an exclusive first look by UK distributors Hotlines.


The range is split into two halves: Tacto, which is carbon fibre or carbon-wrapped kit, and Ineo, made from 7050 aluminium alloy. There’s a choice of bars and stems, plus carbon posts, a bottle cage, front derailleur clamp, seat clamp and headset, as well as various tool/pump/CO2 cartridge holders. Here’s a quick look at some of the key products.

Tacto ISD integrated seatpost

The product that most grabbed our attention was the mini carbon post for integrated seatmasts. A series of nine 3mm spacers let you adjust your seat height in the same way you’d adjust your stem, and you can also change the offset of the forged alloy head from 18-30mm and the saddle angle by +/-15°. Titanium bolts are used to shave grams, and the 190mm-long post weighs in at a claimed 173g. RRP £99.99.

This full-length seatpost is also available, with the same features as the integrated version (minus the spacers and expander wedge), in 250-400mm lengths. Claimed weight is 185g (350mm). It’s only available for 31.6mm seat tubes. RRP £99.99.

Tacto carbon stem

RATIO’s Tacto stem is made from carbon-wrapped 7050-T6 alloy, with titanium screws. Available in lengths from 50-120mm, it weighs in at a claimed 115g (100mm). It takes a 31.8mm (oversize) bar and standard 1-1/8in (28.6mm) fork. RRP £104.99.

3K carbon bottle cage
