    bang from Wednesday rear hub

    Went to loft the front wheel yesterday and there was a bang like a gun shot that came from the bike.

    I spun the rear wheel, and now it makes 2 distinct clicking noises while costing. It has the normal click most of the revolution, but a different crack sound about 3 times during the revolution.

    Not sure what happened - any ideas?

    Someone shot your tire, but your sealant sealed up the hole. The noise you're hearing is the bullet bouncing around.

    Take it in and have it looked at, unless you feel you can take the hub apart yourself. Pull off the freewheel, clean and inspect. I'm not sure, but I think that's a formula hub with sealed bearings? So, perhaps a broken pawl or maybe a broken tooth in the hub body (that would be not so good)? Is there any side-to-side play in the hub? Could be something not so good, but could be something fixable.
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    Replace it with a Bike Hub Store or Hope Fatsno after you figure out what happened to it.

    That "bang" or "snap" sound is the ratchet pawl either slipping off of or onto the drive ring. It seems to happen to a lot of wide hubs and to low-cost standard hubs. I think it has been an issue for a long time. I am betting that there is a little play or flex in your hub when under heavy load and the ratchet pawls don't all engage at exactly the same time, leading one of them to slip or miss.

    If you opened it up you would probably find some ratchet tooth marks where there shouldn't be any, and maybe some of the sharpest edges chipped off the pawls. It'll still work, but the engagement is a little less because of the chipped edges.

    Make sure there is no play in your hub. That'll extend its life.

    It's never easier - you just go faster.

    This^^^^^^^^. Surly should have really marketed the advantages of the offset rear using 135mm hubs but for some reason they decided to jump on the bandwagon. As others noted though, a Hope hub should work better. Are you a heavier rider? I go over 220 and have I think I am on my fourth 170mm hub, lost count to be honest. I have a great lbs which makes it less painful but still a hassle walking a few miles in snow when your "modern" hub decides to call it quits mid ride.....

    I am 150lbs. I just turned over 300 miles on the Wednesday the day it popped - got it in January.

    Taking it to the LBS sometime in the next week.
