You could just get a trials and use it for MUni… Its harder because of the small tire, but thats what i do. 
Should there be any problem with using that rim with brakes?
Nope, I’ve got that rim and its fine, I use it with a magura. It is compadible with rim brakes.
I only ask because it says its the same as a KH only without the “brake grove” and branding. I wasn’t sure what a brake grove was.
I dont know what brand unicycle this is haha
Frame: Impact Gravity
Rim: K1 drilled
Hub: K1 reinforced
Cranks: KH 125mm
Pedals: JC/PC
Seat: KH free ride with CF base
Tire: some what balded Luna <3
Total weight: 11.25lbs 
also like to thank Joe and Will for making my new unicycle possible:)
Dang dude, I thought my seat was low! Looks niiiice though.
I actually raised my seat an inch or so in the past month haha
thanks though:)
I’m getting white Odyssey pedals soon but this is what my unicycle looks like right now:
Specs
Seat: Velo with KH foam, turquoise drawstring and allen bolts
Post: Qu-ax Aluminum
Clamp: Sun Alloy Quick Release - Black
Frame: 2008 Red Nimbus
Rim: Black Nimbus Trials
Hub: Nimbus ISIS
Cranks: 125mm Nimbus Ventures
Pedals: Blue Black-Ops Gummy
Tire: Luna
My flatland setup:
KH 08 street seat with cf.
UDC post
Ajata freestyle frame
Ajata cromo square taper hub
Nimbus ventures 100mm
Sapim double butted spokes
Primo 7005 balance rim
Lightweight tube
Revenge 2.1" kevlar tire
DK plastic pedals, pins replaced with griptape, and i curved the corners a bit.
The cranks are decent for rolls. The ‘rolly’ bit is the same diameter as moments, but not as wide. I’m a bit dubious about the hub. Hopefully the fact that im only using it for flat, the short crank length, me not being very heavy, and the solid axle will mean it holds up.
Its very smooth to ride and pretty light at about 4.6kg. And it’s shiny!
yeah luke!! thats awesome man. looks so so nice. the cranks look amazing, and not to mention the - pedals, seat, tyre!? and the shinyness! haha 
we should go on a flatland ride sometime, just go to the museum and film flat stuff!
looks heavy i would upgrade some things on it but nice uni
I got the new frame in, swapped over the wheel and seat. The mount for the lever is on. Now I just need the mounts to attach the brakes to the frame. I was a dumbass and forgot to order them with the other stuff. Hopefully I’ll have it before the weekend though. I’ll post pics once its all together.
Snapshot
This is the current status:
KH 36 Schlumpf w/ brake (150 mm cranks)
KH 29 Schlumpf w/ brake (137 mm cranks)
QU-AX 28 Cross (114 mm cranks)
QU-AX 24 Muni w/ brake (137 mm cranks)
QU-AX 20 Luxus (114 mm cranks)
QU-AX 20 Trials (137 mm cranks)
These white things on the spokes ate reflecting, so I’m a bit safer when I ride in the dark.
what excatley are they?
Pee-wee is my newest unicycle. He’s got a 12" wheel!
Unless you use some strange lacing pattern, when you upgrade rims you’ll have to use one w/ 48 holes (I think only Qu-Ax make the good ones, they make a wider one than this but I can’t find it).
I’d try not to destroy the rim while I save up for a whole new Muni wheel-set w/ 36 holes (I’d get a KH for the wider rim) and remate the Nimbus frame and wheel, then use that uni for cruising & teaching friends to ride.
Actually, he has a better selection of wide rims than if he had a 36 hole hub. With a 48 hole hub you can use a 32 hole trials rim and it’s a straight forward build. You just skip every third hole in your hub, but other wise the pattern is normal, and you don’t need to deal with different spoke lengths. Until 32 hole uni hubs become more widely available the 48 hole hub is an excellent option for expanding your rim choices.
Not a great photo but I got some new parts and decked my Nimbus X out with blue accents (tire, pedals, saddle, seat post clamp, die valve cap) and 75mm cranks. I need to take a photo in the sun to do it justice.
