Terra S is made from Orro’s own specification 4130 Chromoly steel, which is custom drawn and triple butted to offer a versatile combination of strength and low weight. It's paired with a full carbon fibre fork and the latest in gravel componentry. Boasting mounts galore, the Terra S is an ideal gravel bike for fully loaded adventures with bottle cage mounts in all the right places. The two triple braze on bosses in the mainframe accommodate a wealth of new cargo-carrying solutions, as well as provide alternative positions for the classic two-bolt bidon cage. Tough Gravel Bike with a Steel Frame The durability of steel has been proven over centuries of bicycle frame development. Undoubtedly, a steel bike is heavier than its carbon composite or aluminium alloy equivalents can be made to be. However, its high-tensile strength means that it dents instead of cracking, it bends instead of snapping. It is for these reasons that steel is especially popular with touring cyclists. Despite the old-school appearance Terra S is simultaneously modern in its design with features such as: semi-internal cable routing, a tapered headtube, and thru axles. Load it up. Treat it rough. This bike is ready for demanding routes. Although the frame tubes of Terra S maintain the characteristic round and narrow profile of steel, Orro has a slightly oval-shaped top tube to improve the stability of any bike packing bags which have been strapped onto it. And when the next journey is just the commute, dedicated rack and mudguard mounts allow for more comfortable daily cruising. Shimano GRX Gears The Shimano GRX 600 1x11 drivetrain on this model is ideally suited to off-road riding where the single front chain ring reduces mechanical complexity and the chance of chain derailment. The wide ratio 11-42T cassette provides big gear jumps for fast and effective shifting on undulating terrain. Hydraulic disc brakes ensure power and control are always at your fingertips. Built, Tuned and Ready to Ride Rest assured that each bike is fully built and tuned by Wiggle's team of qualified bike mechanics to ensure your bike arrives in perfect condition.

The 100% Aircraft 2 Helmet sets the standard for high performance protection. With its shell constructed from carbon fibre it's both incredibly strong and lightweight. A full carbon fibre shell features Patent Pending injection molded chin bar integration that strengthens the front area, it also features chinbar rear support for additional reinforcement. The entire helmet is lined with Dual Density EPS foam, injection molded with polycarbonate designed to absorb heavy impacts. As well as the EPS foam lining the Aircraft 2, 100% have added their proprietary SmartShock system which utilises 14 small rubber elastomers suspending the helmet around the head to better absorb linear and rotational impact energy. Ventilation across the Aircraft 2 is an absolute game changer, vents along the chinbar, forehead and top of the helmet pull in plenty of air while massive vents towards the rear of the helmet vent air out to ensure you stay dry and cool. Washable, moisture-wicking anti-microbial liners are comfortable on skin and easily removable for cleaning straight after a heavy session. The multi-point adjustable visor on the Aircraft 2 is designed to give you maximum vision without obstructing your goggles. Finally a sturdy D-ring buckle secures the helmet comfortably in place even when it's tightened right up. The Aircraft 2 is tested and certified according to ASTM (F1952-15), CPSC (16 CFR 1203), CE (EN 1078:2012+A1:2012), and AS/NZS (2063:2008) Bicycle Standards.
