More done
Got my usual arsenal of things back on now:
Front light - Magicshine MJ808 with battery pack above.
Rear light - Knog skink behind battery pack.
Cycle computer - Cateye strada wireless.
and a modified KH spooner (didn’t want to hack into the nice brake lever)
More pics on my G+:
Now for a proper review on the brake setup as I’ve ridden it a bit more.
The nimbus hub looks great, very similar to the current KH hubs but with a larger centre - thankfully they’re glued and pinned now to stop the creaking experienced on the first new style KH moment hubs and the prototype disk hubs.
The spoke holes are a bit smaller than the moment hub holes and not very chamfered on either side. This made some of my spokes rather tighter than they should have been and made me a little concerned when building the wheel up but so far ir’s all good - partly as the hub flanges are aluminium so softer than the spokes.
Apart from the spoke holes seemingly having being designed for 15g spokes the wheelbuild went pretty smoothly - 2mm difference in spokes is pretty much perfect but with my DT comps I could have probably gone with another mm due to the shorter nipples.
Getting the disk on was easy enough, the second bearing was a very snug fit (even with a little extra lubrication) and I’m not looking foward to the day when I have to take it off again.
The wheel then went in the frame perfectly and the machined d-brake also fitted on the bearing like a glove.
Adjusting the brake took quite a while to get it perfect but the mounts on the hub and on the d’brake are definitely spot on.
You are going to need to shorten the brake hose, whatever hydraulic brake you get, so I’d suggest you make sure you’ve got the tools to do it before you start - also having the tools and fluid to bleed the system would be a good idea.
After modification of a spooner, braking felt fantastic and the modulation and smoothness really has to be tried to understand how much nicer it is than HS33s on a rim.
In mud and water (it’s been raining a lot here so had no issues finding some to ride in), the performance felt as good as it had been in the dry but my pads aren’t bedded in yet so that will only get better. Having a constant grinding sound coming from the disk was a little annoying (on my HS33s they were adjusted far enough away so that if I started to get a noise, a quick press on the brakes for a rotation to remove the mud and it was gone) but as braking performance didn’t seem to be reduced it’s something I can live with.
For someone who’s used to rim brakes, quick braking on a disk is a bit weird, it does feel different, not just due to the modulation but due to the wheel twisting a bit as you brake - perhaps rim brakes are less harsh on your spokes… I trust my lacing abilities
The unicycle as a whole obviously looks awesome but there is a slight gain in weight - with the 203mm disk and slightly heavier hub etc I’d guess at a few hundred grams, which I suppose is a lot, it’s worth it though.
