Yesterday my g36 ride was nice but in most of the last 1/3 I was feeling the camber of the curbs so bad.
On this g36 I have a King George tire on a nimbus stealth2 rim (42mm), kh frame.
On my ungeared 36er I have a nightrider tire on a old qu-ax thin rim that has pretty much a V shape. The frame is an old chromed qu-ax frame.
I feel camber more on the g36 than on the ungeared 36er, I don’t know why : tire? Rim? Tube? Schlumpf hub? frame? Rim brakes?
I have a kh freeride saddle and long and short handlebar on both, I hold my handlebars with both hands 99% of the time when I ride.
Before getting the hang of holding a handlebar with both hands, when I rode with my arms free I used them for balance purpose and I was twisted all the time, with or without actual camber.
now when I ride with my hands free I don’t use my arms for balance and I am no more twisted.
Back to my yesterday ride: near the end I was encountering cambers a lot more than on the other parts of the ride and felt it pretty much when holding the handlebar, short or long one, but when I released the bar (free arms) it was a bit better.
I also played with the amount of air. With both 36ers but I don’t have any conclusion for now.
I tried max PSI on the KG tire but still felt the camber, maybe less than when I removed some air latter in the ride.
I suspect the larger rim, but i’d have to swap tires between my two 36ers to be sure it doesn’t come from the tire.
Another detail: I use a schwalbe 29er tube on the qu-ax ungeared 36er and a michelin butyl (even lighter :170gm) on the g36.
The michelin tube is not supposed to fit a 2.25" tire, it’s a 29x35/47 tube. 47mm=1.85"
I don’t know if it plays a role in the behavior of the tire.
of course it inflates to the tire’s dimension but is it torn or something more than the schwalbe tube when a roar/curb is cambered? I don’t know
The schwalbe tube (on the 36er that is less prone to road camber) is a AV19 60-622 compatible, so it fits 2.35" tires.
Edit: and here is the King George 36x2.25 tire:
less square than the NR, but less round than the Cocker.
now, when I’m seating on my uni, even with max PSI (50 PSI) the surface in contact with the floor is flat anyway.
When inflated to the max I feel like it’s ok with reasonably cambered surfaces, but beyond a certain degree it suddenly become sensitive to camber.
contrary to the cocker tire that is round everywhere, the KG and NR has limited area where it’s more or less round, but then there is a gap .
