Just wondering if I will get fling off the chain.
It’s solid at room temp, so no, it won’t fling. Far less likely to do so than liquid lube. However – the first time you ride it bits of excess wax are scrubbed out of the chain, and they are visible on the surface. There’s a slim chance these could drop off on your carpet. But you can remove these with a rag with WD40 or similar sprayed on it, then your chain is clean as anything. You could always try it with some plastic or paper under the bike just to be sure.
However, I am not sure it’s necessary for an indoor bike, since it’s not getting mud and dirt. On the other hand, if you did wax it, you’d probably never need to do it again.
starting to spray some GT85 on agter washing but unsure if that’s acting as a solvent and washing away the wax….
Don’t spray it on the chain – spray it on a rag and wipe the chain down.
