Tyre Pressure

[Boerklong]

I read somewhere you must ask 2 buddies to feel your tyres. One will say too hard and one will say too soft, then go in between.

I dropped the pressure today for my OR Tambo ride to 2bar front and 2.5 bar rear . It felt a bit bouncy when i started off and i thought it was going to bump through but no it was good . It took a few corners to get used to the better  grip it gives . . I could now go in faster and brake later sometimes locking the bad wheel and sliding into a bend and catching it on the way out with a hard acceleration . It definitely   is better for handling . I improved my time by 4 minutes for the 2 laps . Tomorrow im going to try the same pressures on the road and will report my findings .

As mentioned in the previous post i would try the lower pressure on the road ,well what a difference . I kept the 2 bar front and 2.5 rear and i did a 20  km circuit in my area in 47.30 min giving me an average of 25.26kph which by the way is my best so far . . I was able to corner quicker and then speed up faster because of my exit speed . ( sounds like im describing a racing car experience ha ha ) . Ill try .5 up on my ride tomorrow and feel the difference . There really is a advantage /disadvantage to tyre pressure on a MTB . When i rode road it was max pressure for the least resistance on tar . The narrower and smaller the foot print the better .

The best pressure for off road is just before you get a rim strike .On tar i used to pump my crossmarks to 2,5 bar for a road race on my mtb .Currently i am using a wide stans arch M3 rim with 2x 35 width tyre ,that i can run at 1,5 bar comfortably before a rim strike .I weigh 100kg
