Shez.sheridan Posted February 13, 2006 Report Share Posted February 13, 2006 I run a Monty mod with a profile hub. I bought my bike last year off a guy who'd jut fitted a new chain..Originally as you can expect, there was an acceptable amount of chain slack, although now (probably after the chains stretched a bit) it had got to the point where you could touch both sides of the chainstay with the chain, at the same time. To resolve this, as the engagement is still good, but not as immediate as it once was; I moved the wheel back a tad with the monty tensioners (by one notch each side)..now I'm not too sure whether it's over tightened.The engagements instant i.e. the chain is tight, I can only push it up 10mm max with my fingers..& with my hands, if I spin the cranks as fast as I can, it will only backpedal just under 2 full crank revolutions before it stops. However my profile hub still runs fine (although I'm sure there is a larger load placed on it)..Is this too tight?Cheers Derv. Quote Link to comment Share on other sites More sharing options...
Swize Posted February 13, 2006 Report Share Posted February 13, 2006 I would say that is about fine.It should be just on the line of being tentioned if you get me ? Perfect would be if there was a tiny amount of slack but because you are using cams you won't be able to get it like that.Sam Quote Link to comment Share on other sites More sharing options...
Technical Tom Posted February 13, 2006 Report Share Posted February 13, 2006 I think it should be fine, as long as when you spin your cranks backwards quite fast they stay spinning for a bit and is not stopped immediately by the chains tightness Tom.

Davetrials Posted February 13, 2006 Report Share Posted February 13, 2006 It doesnt matter to much unless your running a freewheel. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted February 13, 2006 Report Share Posted February 13, 2006 It doesnt matter to much unless your running a freewheel.Or a cassette hub 10 mm is good at most id say 15mm and min would be about 7mmAlthough at the moment mine is like 2mm lol Quote Link to comment Share on other sites More sharing options...
Jez Posted February 13, 2006 Report Share Posted February 13, 2006 Or a cassette hub 10 mm is good at most id say 15mm and min would be about 7mmAlthough at the moment mine is like 2mm lolI generally do mine up so that I can *just* touch one side of the chainstay. But I've run it looser than that with no problems (you get used to it after a bit, I'm not too fussy on bike setup to to be honest as long as my brakes lock...)And for those who run their chain well tight...I bet you go through more freewheels in a year than the rest of us I also find it harder to align the rear wheel properly when I've got a chain at ridiculously high tension.Just my 10p.

ogre Posted February 13, 2006 Report Share Posted February 13, 2006 I run mine realy tight so i can get 5mm from each side of the chain, i don't like loose chains They scare me (because my mates chain was loose when i snaped it, So i blame the loose chain!)

joewhite Posted February 13, 2006 Report Share Posted February 13, 2006 Hey well i was running mine majorly tight (like the cranks span while i pushed my bike) then my freewheel split when i kickhopped and i could just watch the bearings pour out. so just make sure ur not running it to tight. Ive gone from one extreme to the other as im now running a super slack chain. cheers joe Quote Link to comment Share on other sites More sharing options...
