True on the above guysPulleys expand with heat,
I rotate my belt to find the loosest spot, the way we used to do with chains( remember them?)
Mark loosest spot with a dab of white paint for future reference.
Then with the loosest spot midway between pulleys , I then poke the belt upwards with my finger.
It'll move up about an inch.
To double check when the bikes hot give it the same poke upwards and the belt won't move much at all.
It'll have a little movement , not much and not tight right.
That's as simple as I can explain it.
Once they're set, that's it, ...no need to mess with it at tyre swaps.
Way Vic's are designed the alignment and tension stays the same as long as it not messed with.
Keep it simple.
BP6666VR's method will yield the same result.
Finger poke or belt twist or buy the tool and do it that way, Your choice.
Just don't have it too tight.
Better a bit loose that overtight.
"yella terra" good name, ha ha, i like it ...@BP6666VR ....shouldn't be long now mate till the Yella Terra arrives, I'll call in at A to Z Imports on the way home and see.
Last I heard it was bound for Auckland then either Sydney or Brisbane, if it skips Sydney it'll be sooner than if not .
Went to ride the XC today and it felt super heavy to move, Flat read tire, Damn!!!
And it's almost worn out anyway, has a nail in it!
So I rang Andrew and ordered an E4 and rode the Vegas instead.
Pumped 50psi into the nailed Tyre and checked it an hour later it was 38 so I know when the E4 arrives I can cram another 50psi in and ride the 20 mins to the Tyre shop.
I'll remove the hard bags at my place to make it easier for them to change tyres.
They're good at it and know not to screw with adjustments.
Thank youKevlar is one of the few exceptions to the rule.
It has a slightly negative coefficient of thermal expansion as unusual as that is. So belts do shrink slightly as they come up to running temperature. Everything else expands as Vin mentioned so the belts get a lot tighter as things warm up.
What's bird chip ?Bit loose, but centered, Centered is critical to avoid the bird chirp.
