BeElite Chamois Cream
This is excellent chamois cream for long rides, as long as you don't mind that menthol tingle. It is also almost eternally half price.
This is a thick, almost solid cream that needs a bit of effort to get it moving to spread over your shorts liner – it helps to store it somewhere warm to make it easier to spread – but once in place it stays there. The practical upshot is that it's nicely slippery and stays that way for ages, whether you're out on the road all day or doing a long turbo session.
If BeElite Chamois Cream has a significant drawback it's that it contains menthol, always a controversial ingredient. Do you want to be spreading that around downstairs? We'll leave you to decide for yourself.
If you don't mind the tingle, this is a great option.
