What fork springs? brand and type.
 

looking for some fork spring about £70-80 but haven't a clue what to look for apart from i know i need 90kg fork springs according to racetech

i can get K-tech for £80 but not sure about any others ? and what fork oil would i need? 10w ? and what size spacers would i need, and how much oil is needed per fork leg ?

im 108kg with just t shirt and boxers (racetech say weight without gear)

looking to get these done soon :)

Hagon Prgressives.

whats 108 kg in stones.....you skinny then?

Re: What fork springs ? brand and type
 

Unless he's 8ft tall, I'm going to say no! :)

17stone or so.

lol, I'm old, I don't do kilos ;-)

Thats a bit heavy then :-)

Re: What fork springs ? brand and type
 

Well im 6'1" and quite built and weigh about 100 kilos which is about 15 stone 8 pound.
So yeah quite heavy lol

all right all right i like pies ...... lmao, trust me im losing it lol 20min run every other day about 2.75km

anyyyy wayyy i keep seeing progressive springs are not any good and to go with linear

btw im just under 17stone was 16 start of last year

Re: What fork springs ? brand and type
 

ok so going to go with linear 90kg (reading most of the spring threads say that they are best (correct me if im wrong))

now what most suggest 12.5w MOTUL oil for the front but have head that 15w is ok as well ? 1 litter will be enough for both sides apparently but how much each side exactly ?

and then spacers do you use the standard spacers or cut new one, i have no idea if spacers are included ? and what length would i need to use ?

I fitted K-tech linears in my curvey SK1 and they were direct replacements for the OE, used std spacers. Don't know if that'll be the same for the K3, the suplier should be able to advise.

As for oil, it depends a bit on the make/type, have a gander at the white table halfway down here which lists the viscosities and VI for a load of oils. As a general guide you want an oil with a high VI, in other words the viscosity isn't highly sensitive to temperature.

I've switched to Silkolene PRO RSF, and so far I'm very happy with it. The actual viscosity you use will depend on the weight and the spring stiffness, but I'd guess something round 40-45cSt at 40C would be a start. I use PRO RSF 7.5W which is 37cSt and similar to most 10W oils, but I'm 76kg and use 0.8kg/mm springs. Pick an oil in your chosen range and give it a try.

^ thats complicated :\ lol

and the k-tech ones say direct replacment on the k3 so that's that sorted :)

now just the oil thats confusing me to death lol

Re: What fork springs ? brand and type
 

ok so looking again at the motul oil 15w seems to have ok number of 77.90 at 40c with my weight in mind i supose i would need heavy oil

PS never going to be less than 16 stone, as i do weights as well so muscle will add weight eventually
