    Crankset movement/play

    I just noticed after checking my chainring bolts that I have a bit of play going on. The crankset rocks back and forth up and down barely. Not sure if I just need to tighten down the crankset more, whether the bottom bracket is messed up or what.

    Any help would be appreciated.

    Bike in question:


    Parts:

    Schwinn 1984 Le Tour - Chicago factory 58cm
    Velocity Aerohead Wheels 700c
    Shimano 105 front hub
    Surly flip flop rear track hub
    18t Surly Cog
    19t EAS cog
    Sugino RD crankset
    TA Industries 47tooth chainring
    Brooks B-17 Imperial Saddle
    Planet X Rear rack
    KMC Devil 101 Chain
    MKS pedals
    Goldfinger front brake


    65-68.5 GI
    They say that Obama could be my president but really InI don't care
    They say Biden makes my decisions but he don't, so I'm just not there
    and I'm gonna see the same lies coming in the next 4 years,
    So pardon me if I don't cry when your election goes the way it did

    What crankset/BB are you using?

    Ha! Did you edit to include all the details or am I just blind?

    I'm assuming - unless the square taper interface on your crank arms is damaged from overtightening or riding around with the bolts too loose - the play is coming from the BB.

    Thats what it looks like. I just wanted a affirmation of some sort. I was only riding on loose bolts for ~.5 miles and it was quickly fixed, not skid stops or anything while they were loose too so I doubt its crankset damage.

    Been riding the same cranks and BB for several years without anything until now. Any thoughts on a nice BB? And while I'm at it the only other stock part is the headset. I was thinking a Chris King but I've been out of the game on parts for quite a while.....

    To get a good chainline with that crankset you'll need to use a Sugino 103mm BB (model CBB-103).

    Right on, any thoughts on headsets?

    Tange Levin always works. Velo Orange makes a nice threaded headset too if you want to be a little more fancy without breaking the bank.
