I feel odd posting in defence of Orange, but here goes…
Being a small British company, one thing Orange are very good at is innovation. That is not to say that everything reaches production, that can often be too risky, but I’ve seen dozens of “Strange” badges prototypes over the years, and is bet many more than I’ve seen exist. Orange have quickly brought many new designs of frame onto the market in their range other than the 5, and sometimes they have worked and stayed in the range for a while, and sometimes they haven’t and they’ve been axed quickly to make way for a new product. All the while though, the 5 has always been a key seller regardless. And as BMW, VW, Porsche etc. will all tell you, when you have a product that works and sells itself year in and year out without you having to market it or reduce the price, YOU DO NOT make big changes to it when you update the range unless you want to risk financial suicide!
Love em or loathe em, the Orange 5 is popular for a reason. And it probably goes a long way to ensuring the financial success of the company, which whilst its working, you don’t mess with! Porsche have constantly made small evolutions to the 911 for decades, and it still sells. Had it stopped selling they’d have axed it and brought out a new design to replace it, but whilst it has continued to sell well, it has allowed Porsche to invest heavily in other models and technology’s elsewhere in the market place. The very reason they didn’t make the Boxster any more powerful or better handling (they could have done and still undercut the 911 price by £20k) is because they didn’t want to be a competitor to themselves and risk losing money doing so.
The Orange 5 isn’t for me (aside from being expensive for what it is, it doesn’t appeal), but it is very popular. Putting 650b wheels on it is plenty big enough a change given the company’s reliance on the model in the scheme of things. I wouldn’t be surprised if the 650b 5 is sold alongside the 26″ and 29er versions of the 5, at least for a year or so, cos I know some 5 owners that will he happy they’ve recently bought a new one, or will be rushing out to buy an existing model before they run out, cos they want to stick with 26″ wheels indefinitely.
