Anyone adjust cart set up due to ambient temperature changes?

My cart body was dragging slightly, so I contacted the manufacture. It is 2 years old.

I got a response within a few hours, and they asked if ambient temperature had increased by more than 4-5 degrees recently.

It has - where I live usual summer weather is a bit late, and the max temp in the house has increased by about 8 degrees. (we try to avoid using aircon).

They recommended decreasing normal down force from 1.9g, to 1.7 or 1.5 (min), and increasing VTA slightly.

-0.2g & + 2mm VTA solved the issue. Back in business sounding great.

It was new news to me and I avoided an overseas evaluation and possible repair.

Anyone else adjust due to temperature changes?

Could you tell which did the most good, changing VTF or raising the pivot? Any way , I don’t know what your baseline ambient temperature is, but an increase of 8 degrees F in our house would drive me away.

@lewm

The plan was to experiment first with the smallest change to down force. Then see if that, combined with a small change in VTA did the trick. If these small adjustments didn’t solve the issue then I was to send the cart in for evaluation.

-0.2g was just enough to do the trick but the VTA increase made the rake angle look a bit better.

so to try and answer your question, I guess downforce.

CORRECTION: the VTA adjustment was 2 playing cards so more like +0.5mm NOT 2mm

I live near the SoCal coast so 68-72 is common, but it can warm up quite quicky if the marine layer dissipates and the wind shifts the house can get to 78 or more if especially if we are not home.
