Azarathal Posted December 10, 2012 Report Share Posted December 10, 2012 Heya guys, so everyone knows about stretching the spring on a Chris King hub and how it makes it slightly louder, less prone to skipping (if done correctly) and also have a crisper feel to the engagements. I recently modded a Nerf gun for a friend of mine and rather than stretch the spring behind the air chamber I used 4x 1p coins to add more spring tension. This got me thinking, behind the spring there is a spring retention ring, could I use multiple retention rings / have a 1.5-2mm space made up to go behind the ring and replicate the effect or stretching the spring but without the risk of deforming the spring (Deforming it means the drive/driven rings wont sit in the spring properly causing it to skip). Thoughts? Quote Link to comment Share on other sites More sharing options...
SamKidney Posted December 11, 2012 Report Share Posted December 11, 2012 In my head, it works. Im not 100% knowledgable when it comes to a King hubs internals. Quote Link to comment Share on other sites More sharing options...

Azarathal Posted December 11, 2012 Author Report Share Posted December 11, 2012 It's more theory work at the moment Jack, probably going to never try it. I was just thinking it would stop a lot of stretched spring related damage and skips whilst still giving the bonus'. You could even have a company such as JAF making these in small quantities.

Bigman Posted December 11, 2012 Report Share Posted December 11, 2012 Stretching the spring in a King is actualy a REALLY bad idea, I can't remember exactly the reason why (Hopefully someone from tartybikes will chime in) but I remember my first King had a stretched spring and it tried to kill me on more than one occasion, I replaced it with a new spring and it was spot on for years!!

Alex Dark Posted December 11, 2012 Report Share Posted December 11, 2012 When you stretch a spring if youre not careful you increase the diameter causing it to bind against the hub shell. If youre very careful and twist it inwards the diameter stays the same or decreases negating this problem. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted December 11, 2012 Report Share Posted December 11, 2012 could I use multiple retention rings No. But you could make something to do the same job by spacing out the drive ring. Not that it would be recommended. When you stretch a spring if youre not careful you increase the diameter causing it to bind against the hub shell. If youre very careful and twist it inwards the diameter stays the same or decreases negating this problem. Yep, but nobody seems to do that correctly...!

manuel Posted December 11, 2012 Report Share Posted December 11, 2012 I was just thinking it would stop a lot of stretched spring related damage and skips whilst still giving the bonus'. Wouldn't it be better if people stopped trying to needlessly modify one of the best and the most expensive rear hubs on the market ? Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted December 11, 2012 Report Share Posted December 11, 2012 Manuel: Definitely, but people will tinker with trials bikes. I wouldn't stretch a spring for no reason, or just for the noise factor. Quote Link to comment Share on other sites More sharing options...
Azarathal Posted December 11, 2012 Author Report Share Posted December 11, 2012 No it wouldn't manuel, if it caused irreversible damage 100% of the time then yes, I'd recommend to leave them alone but that isn't the case, you can safely stretch a spring with positive benefits.

dave33 Posted December 11, 2012 Report Share Posted December 11, 2012 They did make 5 different spring tensions over the year if I remember right. Just the stronger spring Quote Link to comment Share on other sites More sharing options...

I don't really understand the benefits in that case, the hub is either engaging or it isn't ? The way I understood the king engages means unless its skipping a tooth or two which you would know about means there isn't really any other benefit other than noise ?

With a higher tension spring you can use thicker grease which will still allow full engagement but lower the rolling resistance. Also the temperature range which the hub is used at will be increased. Not really trials related but heh Quote Link to comment Share on other sites More sharing options...
