    I had to diagnose an S&M BTM frame I had. It was making noise when I pedaled so I figured it was the mid bearings. I put the new mid ones in the bb and noticed it wasn’t fitting in there right. So whoever had it before me had taken the bearings out too much or something bc I had never seen a frame that bad before. Making a clunk clunk sound every time you pedal but in the cold it didn’t make noise at all. I’m an older rider so I take care of my bikes as much as I can. That wasn’t the only thing wrong with it sadly. The head tube was messed up too bc my steering didn’t spin right. It had a big dent in the down tube and bunch of dents in the chainstay. The guy must have thought the frame was the pegs bc this thing was wrecked. I got it for free so I rode it for a while but I was glad to get rid of it.

    I don't think it's the bash guard of the sprocket either

    • @Peculiarsafe83
      @Peculiarsafe83 3 года назад +1

      I’ve had multiple custom bikes since I started riding. I don’t ride much anymore, but I can tell you from experience that majority of the time it’s not the chain or the driver from the hub. The only way it would crackle because of the chain is alignment being off. I figured out it was the bottom bracket bearings. It did that in all of my bikes. I replaced the bearings meaning I had to hammer out the old ones and replace them, once I did that the popping and cracking noises went away. And if you run a guard sprocket, make sure it’s aligned straight because if you don’t the chain will eat up all of the teeth on the sprocket especially if it’s a shadow halflink.

I just flipped my bike upside down and turned the pedals quickly forward and then medium speed and then suuuuper slow to find the exact spots it was Happening during my pedal rotation and I saw the issue immediately pedaking super close I upside down, the chain was wobbling left to right for some reason… even when it’s tight… idk what’s up with that I guess ima have to just get a half link and really be sure to size it nice and perfect

    for people wondering is there a fix... i just rebuilt a WTP arcade, it was happening to a brand new chain and sprocket. swapped the wheel for another wheel and it wasnt happening.. went back to the salt rim and happening again. was driving me fooking nuts. tried loosening the sprocket holder bolt and tried to free the tension at the tenser part, but nothing changed. put the bike down and rode it and it doesnt happen. for me anyway, it only happens when theres no load on the bike... thats why hes saying dont worry about it. so get out there and shred.

    It's a bit late but happy birthday. Hopefully you have learned not to use power tools on your bike to tighten bolts. I'm sure you have plenty of experience using them and have enough knowledge to not ruin the treads or stretch the bolts and such, but I know you know that using power tools is like gambling, you can easily spend money on lottery tickets and know you have a exponentially better chance at losing than winning. Do you like winning? If that means breaking a bolt in a female hub using a impact wrench over and over to eventually cause some serious issues like a broken bolt that you now have to remove?
