Pant leg sprocket interference

Plenty of casual riders will tuck the pant leg into the sock to keep it out of harm's way.
It is not a critical application. Rubber bands will work, as will tape. There are even special bicycle pant clips https://www.google.se/search?site=&source=hp&ei=YwZEWfI4hZfoBJq9gMgL&q=bicycle+pant+clip&oq=bicycle+pant+&gs_l=mobile-gws-hp.1.0.0i19k1l4j0i22i30i19k1.2695.13186.0.14521.15.14.1.0.0.0.105.1141.11j2.13.0....0...1.1.64.mobile-gws-hp..1.14.1154.3..0j35i39k1j0i131k1j0i22i30k1.iYQsqtbaL50 that you can buy for the purpose.
Or get a bike with a chain case.
Or fit a crank protector to the crank.

It's a real conundrum on the style bike that i ride.If you can't peddle thru you have to find something to lean against or a soft spot to do a controlled crash that is in coasting distance.

Wear shorts, problem solved.

Your displayed Avatar looks like you are actually posing for attention with the Sports Car rather than being serious about a cycling related dilemma and the seemingly unnecessary question can nevertheless be answered by using either a cycle clip or riding naked for even more attention.

Cycle clips are cheap enough :--

This issue is on here quite regularly and I am beginning to think that the various posters perhaps suffer with some form of Attention Deficit Syndrome.
Perhaps they should print off the various responses and keep them in a folder for future reference.

More correctly the post title should read Pant leg Chain-ring Interference as the sprockets are on the rear of the bike and on whichever cassette is being used.
