This may be a stupid question, but are you sure there are no steel or otherwise rustable parts that the water may corrode? Or… is it all plastic-lined inside the hose? The thought of using water sounds great! 
And… re: the prices, I’ll do my best! Thanks.
In all honesty - I’m not sure. However, I’ve read several threads in here (cba to search now though) that say trials riders swear by water, and lots of links to trials riders forums to back it up. It may be that in a couple of years time I’ll be eating my words (or tarmac) but I’m prepared to give it a go.

Looks awesome!
After looking at all the types of trips I want to do, I’ve realized that I want a geared 20", 24", 29" and 36". I have 3 non-geared uni now but for the 29" geared the one you have would be the way to go (except I prefer not having a brake and this might change once a ride more with a geared hub).
Sweet!
Hmm…nice Uni STM! I have one just like it.
I spoke to Dmitry at the time about making a Ti handle. It’s doable, I just didnt’ get around to emailing him the specs. I would have made a lower down handle than the T-7, but if Triton was still producing it would have been easy to do a few runs once I’ve perfected the handle I was happy with. I spoke to him about seat-bases too…but the thing is that Ti probably won’t work any better than other materials for flat objects.
The only thing I’d change is the MG-1s. It’s the lightest platform pedal out there, but I hate them. It feels like your standing on nothing. Gimme my Snafus anyday!
Good to see the carpet matching the curtains.
Nice Uni.
That has to be the most customised unicycle I have seen on the forum. It would be worth getting a custom T7 made for it, with a set up like that you could justify the price I think.
Good luck with RTL.

You have “the dream unicycle” period
In my humble opinion, you have “The dream unicycle” (Frame, hub, rim, and brakes). Best of all it’s a 29".
If I were to start from scratch and say money is no object that would be it except id change (tire, seat, pedals)
Nano Rapture tire
KH Fusion freeride seat
Snafu pedals
Vetta cyclometer computer
You are a lucky person. Its definately a keeper.
Why not put in some longer pins? I’ve had to do that on all of my pedals.
Wah Wah - My next pedal.
Low profile and light 478 g, $79 MSRP.
Loving the 29er Semach. I’d have to say this is pretty close to the ultimate touring machine for me as well.
The only thing that might make the uni more practical/lighter for me, would be a handle that mounts on the four bolts under the seat. Something like Corbin’s set-up (not sure if his mounts there, but it is definetely more practical in terms of the amount of metal used.)
Sweeeeeet build!
I would want the KH hub (well, it is what I have!); I’ve twisted/bent too many square tapered cranks.
I also would want it in the 36" size. A 29"er isn’t the ideal touring machine, even geared. (IMHO). More often than not, you’ll find yourself in the high gear. The lower gear is only good for really steep stuff. But, that’s just my opinion!

I think the 29er is a better touring machine, because it’s a lot easier to travel with or ship. Nice setup, certainly.
Can’t you guys read? What makes this unicycle even sweeter than a 29" is that it is a 28".
I was thinking ultimately I would put a 700c x 23mm tire on like road bikes and have a lightweight rim to match- keeping the rotational weight to a minimum and optimising hill climbing efficiency. The cost of cutting back weight would be puncture resistance and also bump absorption, but would allow extremely high P.S.I. and smooth rolling while the road is smooth without glass. T-7 is not ideal as it would weigh as much as your frame, but it will do until something better comes out or if you can be bothered making something custom. I’m not sure what saddle I would consider ideal but lately I’ve been fairly happy with the standard Fusion freeride. It’s been so long since I used my CF airseat- but I doubt it would be more comfortable for long hauls. Awesome cycle! I’d ride with plastic (Oddessey Twisted PC) pedals cos they are cheap and light, but your ones look good too.
I heard back from Florian that the only weight difference between the road and muni hubs was 100 grams! It seems little price to pay for a sturdier product.
Awesome machine! I switched to M-1 pedals a couple of weeks ago and I love them.
I’d go road pedals + half clips, a little less weight, and better at keeping feet on pedals.
I’d dump the T7, go for a stock KH seat + non rail seatpost.
Coincidentally that is pretty much what I have.
If I was wanting to build an absolutely just road unicycle, whilst I wouldn’t go as mental as rowan suggested, as I’ve ridden mikefules 23mm unicycle and it really does suck as a general riding around unicycle, I’d use a less wide rim like say a velocity dyad (315g weight savings), and maybe even try a Schwalbe Marathon Racer 38mm tyre (200g weight savings), although I don’t know if the 38mm tyre might be a bit too much of a gear drop to make up for the 0.5kg less weight on the wheel.
Or, for a multi-purpose unicycle, I’d consider changing to the muni hub + KH29er frame, so I could run the double drilled 150/125mm cranks, giving me something that was good for road or muni without crank swapping. I’m thinking if I win the lottery / do any random bits of contract work etc. I’d like a 24 or 26" geared KH to use as a muni + travel machine.
By the way, the tyre/tube change is a real surprise after the big apple eh? I’m quite pleased I discovered that tyre.
Joe
I don’t know yet. the tyre only arrived yesterday (the Thompson post the day before), so I’ve not had a chance to test them out yet. It’s been a couple of months since I’ve had a Big Apple on there, so not sure if I’ll really notice the difference - but I’ll take your word for it.

When I read up on water filling Magura’s people had problems with the seals corroding but if you add some antifreeze this helps reduce corrosion and should your uni be in a cold place it’ll reduce the chance of freezing. Personally I’ve only used Magura blood (I’ve still got a bit left from my original bottle) but I would use water in an emergency.
I would give this a go - well I will when I get round to it - as when I’ve seen the likes of Joe, John, Sam etc. using them it looks like the way to go (a bad UPD is still a little worrying though)
Nice looking uni but the…snip 
spencer - do you actually use the back bar on the t7? You could hacksaw it off and see if it makes a big weight difference.
If it really messes things up, you can always borrow mine until you get a replacement.
By the way, I’m sure you’ve looked this up too, but magura fluid is pretty similar to citroen suspension fluid, which you can buy in halfords.
I think it’ll be interesting to see what the water does to your brakes - if it lasts a few years, then it doesn’t really matter too much, as maguras aren’t super expensive. It does feel a bit different with the water in them I noticed at the weekend.
they’re the same thing 28" = 29" = 700c. At least on modern bikes and unicycles it is.

Water in the brakes
Even a tiny air bubble can make brakes feel spongy. On trials bikes, where instant solid brakes are real important, they use water because it makes it easy to bleed the brakes. If you are using water, you just put the whole brakes in a bucket and work it, tap and turn, to get out that last tiny bubble.
However, proper brake fluid will feel just as good, if they have zero air in them. It just takes more skill then the “bleeding them in a bucket of water” method, to get all the air out.
I see one other possible advantage. Brake fluid absorbs water from the air. On motorcycles, we change the fluid every year to avoid wheel lock, if the water contaminant boils. But then again, I guess the brakes on uni’s and bikes don’t get as hot. If they did you couldn’t use water.
They can be the same rim but the tires are different. 28" tires are narrower and 29" are fatter in my understanding. They are both 700c to be confusing.
I can’t find an adjective to describe this uni, it’s just too perfect!
The only thing I would change would be a seat like this guy’s
Although you need a carbon fiber base for it.
