Talking about OEM- I’ve seen plenty of examples where manufacturers produce the same product but with less quality materials. Tyres and forks are the main culprits.
If you look at ’14 Revs, I’ve got an OEM set that came on a bike with less adjustments than an RL and painted in a horrible gloss black. You wouldn’t be able to buy these separately in a shop. When I took them out for a service I noticed that they are heavier and the internals feel/look cheaper than the retail forks.
Orange spec OEM forks on their line up, hence the gloss black, however they do use the same internals as the normal forks. Not sure about steerer material.
Same goes for tyres, Nobby Nics are a good example, the OEM tyres on lots of bikes are made from the worst compound imaginable. It feels like solid plastic.
You wouldn’t be able to tell the difference visually with either forks or tyres unless you actually take time to look at them. I think manufacturers are often buying the image, rather than a good functioning product.
Anyway, I prefer the looks of the ’14/’15 Five. The brace and straight TT suit the Alpine more.
