New bike rusty chain

I bought a new mtb for my son in middle of feb 18.
I noticed 3 weeks ago that the chain was showing signs of rust already so I've applied some wet lube.
The bike hasn't been used a great amount, occasionally getting wet, but always kept in the house. Admittedly, we didn't put anything on the chain until 3 weeks ago but I would have expected it to come from the shop with sufficient protection to last more than 6 weeks of light use without rusting.
Would I have grounds to complain?


  • Don't think you can blame the shop for that one.

    Given the rubbish weather earlier this year, the councils put a lot of salt on the roads. This dissolves in the rain and splashes up on the bike and attacks pretty much anything exposed. That will eat through any lube on the chain in no time. Must have been a particularly bad year for it given the way the alloy brake calipers on my hybrid furred up.

    Regardless of age and use good regular maintenance is required. I ride at least once a week maybe more and with the winter conditions I've had to wet lube and clean the bike down a lot to stop the chain and cassette from locking up.

    Presumably following some wet lube it rode fine?

    I put a new decent quality chain on my bike and rode it for one commute return and next morning had some signs of rust, just lubed it up.

    If the bike's wet from use you should always give the drivetrain a spray with a water displacer like GT85 after use, especially if you dont clean it straight after. It will help prevent rust.

    No you shouldn't because it will strip the lube out of the rollers. Just wipe it down. Surface rust just comes off when you ride anyway.

    A good wipe down after a messy ride and occasional wet lube when required. That's what I do and it seems to keep the bike rolling pretty well.

  • Yeah, thought that might be the general response. Been doing some research on the web re. chain maintenance and people are very polarised on how much maintenance is required, from clean it weekly to just whack a bit of wet lube on occasionally.
    It's been a while since I rode much but in my university days I rode daily all year round, rain or shine. I just whacked a bit of oil on whenever it was looking a bit dried out (probably every few months) and never had a problem. But then I was based in a coastal area where they never needed to grit the roads. As one of you said, it could be the salt on the roads that makes the difference.

    Visual inspection after a ride should tell you whether to put more lube on or not, the wetter /muddier the ride, the more chance it needs attention after that ride. If the weather is dry, you could probably go a few weeks without maintenance depending on what lube you use.

    Depends on the bike.

    You can buy a chain for £ 70 and for £ 100 more a complete bike. You cannot expect the chain on that bike to be anywhere near the quality of the expensive chain.

    How much was the bike?

    Better quality chains are chrome plated or Ti nitride coated, cheap one aren't so will rust unless slavered with oil, which then will hold dirt that will wear it quicker.
