i’m hoping to get into the trials aspect of unicycling and i have a question i couldn’t find the answer to anywhere else. first off, let me tell you about my uni if it makes any difference. it’s a cyclepro 24" wheel with square tapered hubs. my question is: if i want to do jumps and stuff, what should the air pressure in the tire be? i’d assume it shouldn’t be too full because it wouldn’t give much but if it’s too empty it could damage the rim. any input?
how wide is your tire?
well first off you shouldn’t be using that for very heavy trials :).
Its all about compromise, you want a fairly low pressure for jumping/hopping but a fairly high pressure for jumping off stuff/not damaging your rim…so therfore you must find YOUR ideal tYre pressure, there is no number that i can give you because it depends on heaps of varaibles (tyre, your weight, style of riding, atmospheric pressure…etc). Just pump it up and see what feels good, too hard to hop then lower it a bit, if your hiting your rim (you will definetly be able to feel this) then pump it up.
P.S. I dont have a pressure gauge on my pump anyway
thanks. my tire is 1.75 width i think. something like that … oh and it’s only 20", not 24".
I would not do hard stuff(Drops higher than 1/2 metre)with that small tyre.
That is exactly the way how I killed my first uni.
I also wouldn’t jump too high. A friend of mine cracked his first uni when he jumped up 8 inches or so.
- Don’t drop more than half metre!!
- Don’t jump up more than 8 inches!!
Generally you shouldn’t do hard Stuff on such a Babyuni.
IT IS DANGEROUS IF YOU BREAK A CRANK OR A PEDAL WHILE YOU DO THAT HARD STUFF! SAVE MONEY, GET REAL TRIAL OR A MUNI, THEN YOU CAN DO WHATEVER YOU WANT WITHOUT BEEING AFRAID! IT IS EASY TO BREAK A UNI LIKE YOURS!
haha my mate’s first uni was just a 1.75 x 20" learners uni and it survived awesome for a few months…he was doing 1m - 1.5m drops, grinding and generally thrashing it.
tis all about technique
my very first uni was some junk unicycle out of a kids magazine with lollipop bearings and a plastic rim and 3 big plastic spokes, the other day i decided to get it out and see what it could handle, i got up to roll hopping down a 5 stair before the rim was crushed…anyways back on topic.
fill your tire up to the recommended air pressure to start with and then lower the air pressure until you find your “sweet spot”
thats what i did.
yeah… or is you have some money just get a 2.175 bmx tire(thats about all you rim will hold) i did that and ran it around 40psi but im 230lbs. now i run a luna trials tire at around 22-25psi. great bounce!
dang thats low, i thought i was running it low at 35psi. (i weigh 190 lbs.)
At 35psi on big drops i will feel the rim tap the ground, but if i go any higher then it bounces me way hard when i do a big drop, and thats never any fun.
its honestly better to get a 20"
a 24" will bend really easy unless u have a muni and evan then it will still not take to much of a beating(not as much as a trials…)
