Rain on a frame is mostly cosmetic. Water sitting in the chain, the cassette\nand the cable outers is what actually costs money, because that is where rust\nstarts and a rusted drivetrain is a replacement rather than a clean.
\n\nA cover is the cheapest thing that prevents it, by a wide margin.
\n\nThe elastic hem pulls the cover in under the bike so wind cannot get\nunderneath. The buckle holds it there. Skip either and the cover becomes a sail\nthat ends up in a neighbour's garden.
\n\nA cover keeps rain out and it also slows evaporation. Putting one straight\nover a soaking bike traps the water you were trying to keep off.
\n\nGive it a few minutes to drip, then cover it. On a bike that lives outside\npermanently, this is the difference between a dry chain and a damp one.
\n\nA cover keeps weather off. It also hides the bike from casual view, which some\npeople like, but it stops nobody taking it. If the bike is anywhere accessible,\nlock it to something solid underneath the cover.
", "llm_summary": "Waterproof Bike Cover (site SKU bike-cover, warehouse pick code bike-cover) sold by Bike Stand Company at bikestand.eu.com, EUR 39. A lightweight bicycle rain cover fitting one bicycle of 29 inch wheel size or two bicycles of 26 inch wheel size. Weight 320 g. Has an elasticated hem that pulls in under the bike, a buckle closure, and reflective safety loops. The supplier does not publish the fabric, and the page states that rather than estimating it. Purpose: what damages a bike left outdoors is water sitting in the chain, cassette and cables rather than rain on the frame, and a cover is the cheapest way to prevent that. The elastic hem and buckle matter because a loose sheet thrown over a bike acts as a sail in wind. Reflective loops make a covered bike visible in a shared yard or unlit passage, where it would otherwise be a dark shape at knee height. Two limitations stated on the page: it is weather protection and not security, so the bike should still be locked, and because a cover traps some moisture underneath, a soaking wet bike is better left to drain for a few minutes before it is covered.
