    DIY Chainring Guard

    Well, here's more fodder for the group.
    ----
    From time to time, I've caught the bottom of my jeans in my chainring, even though I wear an ankle strap.
    Unfortunately, there isn't much available in the way of chainring guards.
    I did look at the Kool Stop Chain Disk, but it wasn't what I wanted.
    So, I bought a 52T chainring off ebay for $9.99 and custom fit it to my 44-32-22 crankset.
    With this setup there is no interference with the derailleur shifting to all three chainrings.
    And I personally think it looks better than some plastic disc.
    And it works great.
    ----
    Oh, and for those who are curious about the grey PVC.
    That's my DIY fool-proof chain jump stop.
    No more granny gear chain hops.

    I like that DIY chain jump stop and grey PVC blends in with the color scheme.

    I don't see any teeth on that 52T chainring.

    Here in Oregon people are open to everyone doing their own thing.
    All the upright bicyclists are quite friendly to me and always wave.
    As for the jeans, I always wear whatever I'm wearing at the time.
    Whenever I feel like going for a bike ride, I get my water and helmet and go.
    For cool mornings I have my jeans on.
    For hot afternoons I have my shorts on.
    I've never worn any of those fancy bike clothes.

    +1 on the no fancy bike clothes, they do nothing for my cadence or speed either. Like your homemade chain guard, something I would do too.

    I've seen some HPV racers do something similar by cutting appropriately-sized disks out of plexiglas. That way, they can get any size they want or need.

    In place of the home-made chain jump fix, try the N-Gear Jump Stop, $12.40 shipped (using paypal to pay) and the seller is awesome to deal with.

    Driveline chainring guards on eBay are another alternative

    Over a year ago I (based on postings by another recumbent rider either here or on BentRiderOnline) purchased a different item from eBay. Driveline (made in China) sells recumbent-sized (50+ tooth sized) chainring guards. I received a very nice CNC'ed chainring guard complete with mounting spacers and correct length chainring bolts. Being a smooth chainring guard, there aren't any teeth to embed into anything you crash in to or catch your clothing. These are still available on eBay. For example, there is one sized to to guard a 53T, BCD 130mm chainring (a common recumbent chainring size) for $17.99 + $8 shipping from gobike88:

    If you prefer a made-in-the-USA guard of the proper size, they are available (even with custom CNC engraving) for roughly twice that price. For example, I think Purely Custom made them in the size you want (although not presently listed on their web site I'd still contact them), custom engrave if desired, and among their "Bash Guards" model lines offered, one has (although I do not know if it is available in a 53T size):
    Soft Touch:The new standard in bashguards is the Soft Touch. This revolutionary product is unlike any other. It's thermoplastic polyurethane outer rim protects not only your bash guard, but the obstacles you come into contact with as well.
