    Hitting WATER DRAINS (in San Francisco, Market street)

    I always knew to avoid water drains because our skinny tires could get stuck, but those are only for water drains big and long enough to get stuck in. I usually go over ones that have tiny holes that can't do any damage.

    Riding down market street in SF I knew there were some huge water drains (are they even drains? they're huge, anyways...). I biked over a few water drains which were fine for my tires since the holes were tiny and they ran perpendicular to my tires, not parallel.

    So i overgeneralized and headed towards another drain only to see that these holes were much larger and they ran parallel to my tires. They weren't huge so i didn't get stuck but they were big enough to cause pinch flats.. flatSSSSS.

    I tried going diagonal over them and lifting the weight off my front/rear tires but it was already too late.

    Anything similar happen to anybody else before?

    An example of how bike unfriendly/ uncoconscious things really can be.
    I believe those are vents for BART..or so i thought.

    They have these in my city. I ate **** on one and got a pretty
    gnarly scar on my eyelid from the event. Later, I was working
    when the mayor came into my business. I told him how ****ed
    up those drains were, and I had some pretty serious wounds on
    my face to prove it. He was sympathetic, but hasn't done ****
    about it, despite his efforts to make our city more bike friendly.

    I broke a rear wheel on one when riding home after work... It spanned the width of the street and was probably only 2" long. I hopped the front wheel over without issue but since i suck at t3h bunny hop the back wheel dropped right into the slots. Pinch flatted and b0rk3d the wheel (it was way out of true and the braking surface has a nice fat dent in it). I didn't fall but i did have to call my girlfriend and get a ride home from her.

    Needless to say, i avoid that road nowdays.

    in b-more we have some really bad drains where if they are parrallel to your tire they can totally swallow your whole tire. it's pretty easy to see them coming if you are paying attention, though sometimes they can be hard to avoid in heavy traffic, but i was riding last winter in the snow and while most drains were a little melted through and still visible, one was totally covered and i plowed right into it. luckily i wasn't going too fast (12mph-ish) since i was in the snow but boy that sucked. obviously pinch flatted my tire. to its credit, my deep v got a slight bend in the lip, but overall stayed totall true

    p.s. the worst thing is that the drains are square, so the grate can be placed horizontally just as easily as it can be placed vertically... EASY fix

    for a while there was a city council member running around town ordering that all of those drains got turned so they were perpendicular with traffic. that was nice. i normally just go around. i really hate the huge metal grates on market (i think those are the bart vents), especially when its raining. also the bridge by the baseball park is pretty awful. im so scared of crashing on it.

    The bridge at giants ballpark is fine for 25 width tires. I've also rode over the bart vents (center lanes on market) and that sh&t is not good for your wheels at all (bent rim).

    what about those tracks for the silly-a$$ trolleys ya have running up and down market--
    they were easy to skip over on my cyclocross bike during the critical mass ride but I thought
    they were a bit treacherous.

    I hit one of those coming across the 10th st bridge(not sf, pgh) balls out when a car would not move over and had a wonderful 3 course meal of stem, side of car and pavement. I was able to get up and make it home atleast. Crazy.
    this bike is a pipecleaner

    To be more specific, I was biking at night so it was even hard to see those large 'bart vents'

    And yes, I had to hope over those damn tracks also. Coincidentally, I was actually talking to someone today about biking on market and he actually showed me his scars from a broken wrist + elbow from those tracks.

    crazyyyyy

    Stay in the bike lane on market everyone.

    Our local flavour is intersections where N/S/E/W streecar tracks converge for straight-through traffic as well as alternate turning tracks for each direction. Hello, deathtrap ... especially when every driver around you is switching "lanes" in the middle of the intersection and gunning it to try to get around the parked cars up the street.

    I've avoided those for about 17yrs now.....ever since I trashed a rear wheel when I hit one taking a corner.


    Wasn't in SF nor was it on a SS/fixie, so I guess it doesn't matter.
    Who cares what your bike weighs, just ride it!

    someone from santiago, chile (i think) posted a pic of a drain that had long enough holes to fit the entire bottom half of the wheel up to the fork. i think it was in the expat shames thread
