JHS preload top caps for curvy and springs.
I'm currently sorting out my front end and had a couple of questions.
When looking through some bits on the JHS website I saw the adjustable preload top caps and spacer/shim kit... http://www.jhsracing.co.uk/~jhsracin...susp_steer.htm Has anyone used or know anyone who has used these and are they worth the cash? I also thought I'd add a poll on the thread as I've heard a lot of mixed feelings about progressive and linear springs, I thought this would be the easiest way to find out peoples thoughts on the subject In advance... Thanks |

I have linears with 15W oil and a set of caps from robinsons, there dialed in about half way, and the whole front end feels a million times firmer

Re: JHS preload top caps for curvy and springs.
Preload adjusters aren't necessary, once you've decided on a setting you probably won't change it, just use some suitable tube for your spacer, which you'll likely need to cut to an appropriate size anyway as most springs aren't supplied with spacers, and from your question I imagine you're considering changing springs.

next week I'll be putting new springs in. I've heard a lot of mixed opinions on what people prefer. I changed the fork oil the other week as it's never been done in over 20,000 miles. I put in 15w oil but it feels horrible. It seems like theres not enough rebound or something? |

Re: JHS preload top caps for curvy and springs.
Spacer length will depend on the springs you fit. I'd assume you are fitting springs with resistance (dunno proper term) suitable for your weight? If that's the case, try the standard spacers first and see how the pre-load is with those - you can decide after trying this if you need longer or shorter spacers.
Pre-load is used to set the amount the bike sags under your weight, so there is no hard and fast rule on spacer length required. You are aiming to have a few mm (5-10?) of sag in the suspension under the bikes weight and 35-40 with you on board in full kit. Those are the numbers I favour for road riding, others use different numbers depending on riding style / preference. |

Re: JHS preload top caps for curvy and springs.
Progressive springs if your going to be happy to leave it at that, if you want to do more to the forks ie emulators, then you need linear as you cant set the damping for a variable spring rate.
Progressive springs are good at what they are intended for ie their progressiveness makes up for when there is poor damping and a cost effective fix, but ultimatelt linear and correct damping will perform better. |
