Bike frame design is heading in some exciting directions with new materials and manufacturing techniques. One of the first things in this new wave of technology was the introduction of 15 and 20mm rear drop outs. The idea behind this at a simplified engineering level is ‘bigger & stiffer’. In the real world this means less flex and greater power transfer to the ground. I have 15mm reared Dkoi & 20mm DK Race Bikes and both these frames come with adapters to take them down to your ‘normal’ 3/8 axle. They have worked great but as soon as I spotted the prototype of the Profile 15/20 hubs in a U.S. magazine I knew I wanted them, to use my frames as the designers intended. I’ve run a 20mm Alius hub and fork combo for around a year so couldn’t wait to do the same at the back of the bike.
I was very lucky to have one of the initial sets to land in the UK and I have to say when I opened the box my first impression was amazing. The engineering and attention to detail was of the highest level, exactly what you expect from Profile Racing products. BMX Talk team rider Harley Taylor was also one of the lucky ones to get hold of a set so expect further updates from us on real world long-term tests.
Pro’s / Cons
Pro: The tried and tested Elite hub with its 204 points of engagement; not an instant engagement but VERY close.
Con: This isn’t really a con just an observation; the front 20mm Profile hub has 2 ‘traditional’ bolts rather than a through axle. My Alius Hub & Fork combo has adopted the through axle approach and installation is a very quick and easy process so we shall see how life is with 2 bolts again.
