echo_rob Posted June 25, 2008 Report Share Posted June 25, 2008 hey there, Are deng freehubs (adamant, echo, Gu, czar etc) decent? I see that they're cheap but is that because the quality is low? thanks rob Quote Link to comment Share on other sites More sharing options...

Mat Smith! Posted June 25, 2008 Report Share Posted June 25, 2008 no there not. close the topic lol. Matx Quote Link to comment Share on other sites More sharing options...
psycholist Posted June 25, 2008 Report Share Posted June 25, 2008 A friend of mine had one fail when the ratchet ring inside the hub started to spin forward under power. It was so loose you could turn the sprocket forward by hand within minutes of the slip first being noticeable. Got a warranty replacement, so hopefully that will last better.

Skoze Posted June 25, 2008 Report Share Posted June 25, 2008 On a scale of 1-10, how much do you value your face? Some seem to be ok, just what seems to be the majority skip/implode very quickly. Quote Link to comment Share on other sites More sharing options...
The Duck Posted June 25, 2008 Report Share Posted June 25, 2008 Countless topics on this already. A mate of mine has had one for over a year now on his mod. It just doesn't skip, its always been fine and he doesn't even maintain it. Its been taken apart and cleaned out once since hes had it.

J Trials 31 Posted June 25, 2008 Report Share Posted June 25, 2008 They are good if you get the freewheel hub. Got one of those works awesome! The wheel is for sale if you live in the US. Probably not though huh. Quote Link to comment Share on other sites More sharing options...

Bearded Midget Posted June 25, 2008 Report Share Posted June 25, 2008 you might get one thats good you might get one thats bad...but theyve all got crap amount of engagements! Quote Link to comment Share on other sites More sharing options...
psycholist Posted June 25, 2008 Report Share Posted June 25, 2008 I wouldn't call 48 engagements crap really... Quote Link to comment Share on other sites More sharing options...
Mat Smith! Posted June 25, 2008 Report Share Posted June 25, 2008 you might get one thats good you might get one thats bad...but theyve all got crap amount of engagements! same as a profile/pro 2/tensile freewheel? Matx Quote Link to comment Share on other sites More sharing options...
J Trials 31 Posted June 25, 2008 Report Share Posted June 25, 2008 Luvin the avatar matey Yeah, looks as though you stole it from me!! same as a profile/pro 2/tensile freewheel? Matx Actually it's better than a tensile. I've got both and the Echo is smoother. Quote Link to comment Share on other sites More sharing options...
The Duck Posted June 25, 2008 Report Share Posted June 25, 2008 Yeah, looks as though you stole it from me!! Actually it's better than a tensile. I've got both and the Echo is smoother. Yeah, its actually equivalent to a freewheel with 72EPs. Because EPs on the back = (EPs on the front x 1.5) Quote Link to comment Share on other sites More sharing options...
basher Posted June 25, 2008 Report Share Posted June 25, 2008 Yeah, its actually equivalent to a freewheel with 72EPs. Because EPs on the back = (EPs on the front x 1.5) How does that works out, ffw = freewheel engages -> chain slack taken up -> fixed cog -> power is put down to the ground freehub = fixed cog -> chain slack -> freehub engages -> power to ground So the pick up is exactly the same, may feel different due to the order it all happens but that preference.

psycholist Posted June 25, 2008 Report Share Posted June 25, 2008 Yeah, its actually equivalent to a freewheel with 72EPs. Because EPs on the back = (EPs on the front x 1.5) It's exactly the opposite (Assuming you've got a 1.5:1 gear that is). 72 engagement points on the front (An ENO for example) with an 18:15 gear is the same as having a rear wheel with 72*15/18 = 60 engagements on the rear...

JonMack Posted June 25, 2008 Report Share Posted June 25, 2008 Yeah, its actually equivalent to a freewheel with 72EPs. Because EPs on the back = (EPs on the front x 1.5) Nope. It's dependant on ratio. CK on rear = 72 EP Ratio = 18:12 = 1.5 72*1.5 = 108 So for a mod with a CK the engagements at the pedals is 108. If you're running a Profile with 18:12 then it's 72 EP at pedals, but if you're running a Pro 2 with 18:15 then it's 57.6 EP at pedals. All dependant on ratios Quote Link to comment Share on other sites More sharing options...

bollo you ball-bag Posted June 26, 2008 Report Share Posted June 26, 2008 (edited) huh surely a hub or freewheel can only engage a set omunt for example, a hope pro 2 uses ratchets. im not sure but say it has 24 ratchets inside, offset into 2 groups of 2. The the hub can only engage 48 times, no more no lesss, unless a pair of ratchets fail. the gear ratio doesnt affect how many time a hub engages, it just affects how many time the rear wheel is forced to turn as a result of one full turnof the cranks. for example you run an 18:12 setup and your rding up a steep gradient. for every 360 degrees you turn the cranks you'r rear wheel will turn 540 degrees. i have used a gradient in the example as on flat ground the rear wheel is likely to freeewheel.

BenLeacock™ Posted June 26, 2008 Report Share Posted June 26, 2008 am thinking of getting one on a spare wheel incase something hapens to my wheel i have now again. are they worth buying for a spare or not ? Why not just buy spares for your king have them ready ? So you could like do a quick swop ? Quote Link to comment Share on other sites More sharing options...
psycholist Posted June 26, 2008 Report Share Posted June 26, 2008 the gear ratio doesnt affect how many time a hub engages It does when you're comparing front freewheels and rear freehubs and trying to decide which gives the least crank movement before engaging. If you're on a front freewheel the number of clicks divided into 360 will give you the number of degrees the cranks can move before engaging (5 degrees for a 72 EP freewheel). If you're running a rear hub, the gear ratio is acting on the rear hub through the cranks (And if the gear ratio is greater than 1:1) the same number of clicks on the back hub will leave less angular movement in the cranks before the drive engages (18:15 driving a 72 click Chris King will give 4.1667 degrees before drive engages). This is not 100% correct as there is a certain amount of backlash before most freewheel mechanisms engage, which will add to the angular movement required, but it's still a damned sight better than a standard Shimano 16 click hub, where the same gear ratio gives 18.75 degrees movement before engaging...
