Anyway, you’ll find the STC layup in the tubing throughout the frame, with the paint job exposing it on the underside of the downtube, toptube, seattube and chainstays, as well as a similar-looking pattern in the fork.
Geometry is key as far the Gold STC is concerned. It may be Orro’s flagship frame but, in line with the brand’s DNA, the Gold’s geometry is aimed at the endurance rider. For our medium model, that means you get a 554mm toptube and a 174mm headtube, for a stack and reach of 572mm and 384mm respectively. The long 1005cm wheelbase means the bike feels fairly relaxed beneath you, responding to inputs with a calmness and stability, while the 71.4 degree steerer angle pushes the trail forwards to give a relaxed feeling through the front of the frameset.
Downstairs the frame houses a PressFit BB30 bottom bracket, although the frame is relatively slender around the area compared to some race-endurance bikes. If Orro’s claims ring true, the STC layup should help compensate for this. The seatstays also follow this trend and follow a slim design before joining into a flat, leafspring-like shape at the seattube junction.
The ride – gran fondo pedigree with a racy instinct
The one area where the Gold STC really flies is in how it seemingly glides over the road with such little resistance. Naturally, this is partly down to the rolling stock, which we’ll cover more later, but the frame does its part by providing a stiff and responsive platform on which to put the power down.
Reminiscent of bikes with a racier focus, there’s no discernible flex or lag beneath you – a characteristic you might expect more of with a bike that has to distribute power input across a long wheelbase. Instead, on rolling terrain, you can really get down to the business of powering over short climbs out of the saddle, giving the Gold STC a rewarding feeling when you chuck it around beneath you, helped by the low overall weight. The Gold STC may be aimed at the gran fondo market, but it’s ideal for those riders who want to set a quick time.
The long wheelbase naturally means the frame isn’t as immediate in its feedback as pure-race-bred machines, but as soon as you sit down and settle into the all-day kind of riding Orro expect you to do with the Gold STC it sings, effortlessly and smoothly progressing up the climb. No, it’s not all things to all climbers, but it’s a great middleground for the endurance rider.
