Underwater pedalling bad for bottom bracket?

My commute this morning was wet to say the least. It included chancing it through a couple of "road closed" sections from flooded fields. No big deal but I did find myself on each occasion pedalling with my feet submerged on the downstroke and the bottom bracket just underwater.

I'm thinking that this is all run-of-the-mill stuff in the life of a CX rider, but do I need to get my nearly-new 105 bottom bracket checked/regreased?

    I did the same in the summer on a BB30 bike, i took the crank out, dried, cleaned and regreased it. There was plenty of moisture in there and for the sake of ten minutes effort it was worth it.

    If you leave the water in there, expect to replace the BB sooner rather than later. Even if you just take the cranks out, lie the frame on it's side and allow it to trickle out
    Make mine an Italian, with Campagnolo on the side..
  • Nightmare - I wouldn't have done that myself. The seals might have kept the water out but if not I bet there were a lot of particulates in the water that could have deposited themselves on the bearing surfaces. I'd get it cleaned out if I were you.
  • Thanks for the advice, chaps!
  • Huh? Bike engineering must have declined recently. Are you seriously saying that we cant ride through puddles anymore?

    My BB was under water for 200 metres so I was expecting water to get in there. I had water running out of my RS80 rims too, all because I was too lazy(wet and knackered) to take a four mile diversion

    Unless you are sure they stayed dry I'd also check the wheel hubs. Not doing so cost me for a new front wheel a few years back.

    I'd second that - I had to upgrade my wheels a couple of months back as the originals were ruined by water ingress. What a shame.

    the rims will have a small drainage hole somewhere just take them off the bike an lay them on the floor with the drainage hole at the lowest point.
