• Are there any environmental concerns with sealant?

    If you want to be strictly on-point, avoid the glitter trick (microplastics). The rest of the goop is pretty harmless, it's mostly water and most of the rest is natural latex, which is food for microbes. You're probably doing more harm with the wear particles from your synthetic rubber tread.

  • Yeah I wouldn't roll a turd in glitter. In that case what's the test approved sealant? I've never had issues with Stans so far mind, except for maybe it not lasting all that long.

  • Caffe Latex is good IME, Stans is my default simply because its the most widely available, Orange sealant I haven't got on with as well as Stans, the Finish Line stuff is absolutely useless.

  • what's the test approved sealant?

    I'm using Schwalbe, which is apparently the same as Stan's but it was cheaper at the time of purchase. On the other hand, don't ask me, I literally haven't ridden either of my tubeless bikes this year, and I don't ride them much any year.

  • I’ve used Stans based on availability, schwalbe blue dot since I got it with my schwalbe tyres and now on caffelatex fro @thecycleclinic I must admit they’ve all sealed pretty well and I’ve never been worried which one is in the tyre. I probably won’t go back to Stans though. Not sure why which isn’t that helpful.
