ORRO TERRA 105 GRAVEL SE DISC
£1499.99 > Gravel by name and nature?
Orro’s Terra Gravel features a triple-butted, part hydroformed aluminium frame with a carbon fork, rack and mudguard mounts, hydraulic discs and a tidy component spec. As supplied the 50/34 chainrings and 11-28 cassette are roadorientated – you’ll climb most things on the lowest gear, but away from the tarmac we found ourselves in the big ring and biggest sprockets too often.
The bike will take mudguards with the 28mm Vittoria Zaffiro tyres fitted, or 32mm rubber alone, which would improve things off road, as the higher pressures needed for 28mm tyre security on rough stuff makes for a choppy ride. Shimano’s 105 with RS505 levers ensure reliability and good performance, and Fulcrum’s R700 wheelset is wide and keen to spin, if not particularly rapid. Deda’s bar and stem, and Prologo saddle complete a nice but slightly weighty package, which hurts swift progress.
Most road bikes have settled on 160mm disc rotors up front, so having a pair of 140mm rotors here is unusual. Demon descenders and bigger riders may prefer to swap the disc for peace of mind.
The Terra Gravel doesn’t enjoy an especially light feel on tarmac with 60psi in the tyres, and dropping to 50psi for long, potholed gravel stretches, the ride was accurate and composed, but not that refined.
