Trials unis are becoming more and more specialized as we speak. Just look at the XTP! .
Street should move on as well, I think, it’s the way forward for any discipline that wants to become successful.
A long time ago, several decades infact, BMXs and 20" trials bikes were practically the same, the trials bikes were copies of the old 60’s and 70’s styles of BMX bikes. But, as the years moved on, the two different types of 20" bikes became more and more different to eachother, and now they are almost perfect for their respective riding styles.
BMX/Trials bikes from the 70s-ish were almost identical, now:
BMX:
-Tough, short, steel frames, with 14mm dropouts for the needed strength.
-steel hollow cranks with multi-splines (think KH Onza/Profile style stuff) as well as the steel pinch-bolt type cranks with 8 or 10 splines (think Qu-Ax/KH 2004).
-chunky flat pedals (Odyssey JC pedals are a typical example)
- wing-style handlebars, almost always steel.
-short, fat stems.
-sometimes BMX frames and forks don’t have any brake mounts for brakeless riding.
Trials bikes:
-Reasonably tough, long, aluminium frames, with 10mm dropouts.
-aluminium solid cranks, normally square taper or ISIS (never Profile/KHOnza type stuff).
-caged low-profile grippy pedals built for strong grip.
-either ‘flat’ or ‘riser’ handlebars, almost always aluminium
-very long stems.
-almost all frames and forks have 4-bolt magura mounts, or disc brake mounts
Just see how different those two have got, and the two sports have gotten so good as a result of the bikes becoming more and more specific over the years. If BMXs and trials bikes remained relatively similar like Trials unis and so called ‘street’ unis do, then BMX and biketrials would never really be as big or successful as they are now.
I think the Koxx XTP is the first of many CNC machined aluminium unicycle frames, soon other brands like Onza, Qu-ax, and KHU will be catching on. Flat crowns will probably start to disappear on trials uni frames, and CNC’d curved crowns will start to become standard.
If trials is evolving so much already, why shouldn’t street? 2007-2010 are probably going to be the years we see unicycle components really become specific to disciplines. We may even see a dramatic difference arise between Freeride and XC unis. Of course different disciplines overlap eachother here and there, but having a specific uni for a specific discipline helps loads: just how much better are freestyle unis for freestyle than trials unis? Just how much better are munis than 24" commuters at mountain unicycling?
Just my thoughts, put into debating-mode :o . More street riders should be brave about this, and do what Spencer has done, like when you next break something on your trials wheel, get yourself together a GOOD 20" BMX-orientated uni wheel, and see the difference.
