I have seen threads like this in the past but nothing recent. Take a picture of one (or more!) of your currently used unicycles and post a picture, so we can see the range of what unicycles look like these days. Maybe talk a little bit about the parts. I can start.
This is my 26er. The oldest parts of this (the wheelset, including the hub) are from a unicycle I bought in response to one of my first postings on this forum. Since that time I have replaced or tweaked various parts for different reasons. The frame was a result of not looking after the original Nimbus frame. The short (89mm) cranks are to give me some speed as I am currently using it for road usage. Similarly the fat frank road tyre, instead of a more aggressively treaded tyre. The green seat post clamp and pedals are actually intended to be with my URC 24 (which has a green frame) but I put them on here for fun contrast against the red frame (well unless you are colour blind, in which case perhaps the contrast will not be obvious at all ). No brakes. The frame has a brake mount but I would need to rebuild the wheelset with a hub that supports a disk to make use of that. Perhaps one day in the future.
