I enjoy riding with my tyre at around 15 PSI much more than having it hard. This, for me, is quite soft and bouncy which gets me more height hopping up things and a nicer landing dropping down.
I know I should have it harder for the health of my uni, but I was just wondering what the worst was than I could do by dropping off say <1.5m Obstacles, other than maybe puncturing my inner tube and wearing down my tyre quicker.
Yould get flat spots in your rim and your spokes could end up taking more of the impact on your spokes, why not try say 20 and see if you can notice the difference much? Also can i just ask when you hop sideways at such a low pressure does your tyre go all werd and like fold sidewards? mune does at anything less than 30 but it is a 20" trials tyre not a 19" trials tyre.
My tyre does not go sideways, however it folds downwards [this will obviously wear it out]. My tyre on my old learner uni did this cos I had a normal sized (thinner)rim [I assume].
The seat which came with it cracked sumwhere and that made it all bendy bu stayed in shap for a while, then i got a seat with a handle, aslo the seatpost tabs at the top bent slightly with the seat but straightened them out now and its fine with the stronger seat on it, apart from that its all fine, and ive done about 2 ft drops with some harsh landings and i weigh 12 stone the seat broke just scrwing up on freestyle though, unfortunatly i dont know where you can get the 2.5 tyre from but ill get the make later, it came stock on my trials bike and im just robing it off that! Oh yeah the plastic pedal axels are slightly bent but its hardly noticable and the cranks are still true!its an excellent uni! ive had it a year and yesterday was the first time the cranks came loose, but that was due to me changing the pedals earlier on.
About the uni frame, could you get me a price for postage please and ill get ym dad to pay for it via paypal
