    Slippage

    I ride a 29 GT SSpeed
    I have noticed riding downhill that there seems to be some slipping or so seems like it each revolution
    When I put direct firmer pressure on the pedals, I dont feel it but when I lift some of the weight off the pedals l feel some slipping. This I noticed is always on a paved road surface.
    My question is:
    Is it the rear hub? or is it slipping in the pedals?
    Dont notice any of that on the trails going up hill etc.
    Chain is adjusted correctly lock ring against the hub is tight.

    Any thoughts?

    What feels like it's slipping? The crank? The hub?

    Slippage

    Upon further investigation I found it is coming from the rear hub under light pedal pressure When I am firm on the pedals I do not feel it but when I let up on the pedals I get it do it

    Any advice?

    Can't get what u r trying to explain. It's hard to understand. What hubs are u running? To me u are describing poor engagement on the rear hub?

    What we're not getting is what exactly is slipping. Is it a jerk or a slow sliding? If it's not happening under heavy load then I doubt it's anything to do with the chain skipping a tooth.

    Protip: Use punctuation; it helps.
    All of the true things I'm about to tell you are shameless lies.

    Slipping

    On the forward motion of the pedals each side there is a slight slipping feeling going on when I dont have alot of weight on the pedal
    However when I put a more direct pressure on the pedals forward pedaling I not feel the slipping????

    I watch down at the rear hub and think it is there The crank and bottom bracket seem fine
    The chain seems the correct tension

    Can it be in the rear hub lacking in grease or ?

    I think what u are refaring to is play on the engagement of the hub. This normal in a lot of hubs with conventional engagement systems. Run ir over to ur LBS and have them look at it.

    Rear Hubs

    So if I understand correctly this is Normal?

    What is the correct term for the hub I have?

    It is a single speed and engages forward and free wheels back ward

    Maybe it has been like this since the beginning but never noticed it being this sloppy or slipping like

    It has never resulted in me being able to pedal forward tho

    Thought maybe there would be some light main grease or ? I could do

    Thanks

    Ok conventional hubs ei (xt,hope, AC, etc) have convetional engaging mechanisms with 24 points of engagement. This allows for a litle play on the hub when you pedal forward. Now CK and Hadley have 72 poe(points of engagement) and I9 have even more. Meaning it allowes foe little to no play when u pedal. This is particulary advantageous on SS bikes specially when ridding technical stuff. Now there's also a possibility that ur hub has a problem. That's y I mention to run it to ur lbs and have them look at it. I can tell u this. I own both CK and I9 and I can never go back to a convetional hub after getting used to the quick engagement. CK are fast but I9 is sick fast. 0 play on them. I could noticed the diff(very little but still there) from my I9 to my kings. so good luck hopefully there's nothing wrong with it.

    AFAIK, the only zero lash hubs in wide use are fixed gear hubs. That's fine, as long you don't like to coast. It is, in effect, the play, or lash in the hub that allows it to coast between engagment points. Of course, that doesn't happen on a fixed gear which has "virtual" engagement roughly equal to the congruence of the chain to the tangents of the chainring and cog. ("Engagement" approaches infinite with proper chain tension).

    There was some noise being made years back about a freewheeling roller clutch hub from a company whose name I can't remember, probably because I've never seen one, and never seen a ride report about one in a mountain context. Preserving the ability to coast with virtually infinite engagement points sounds like the holy grail.

    Perhaps it is cold out? And the grease may be a little heavy for the temp.
