Fork Springs

Post by Luders »

Just giving my forks a service and my springs are now at their service limit.

Does anyone know if they are still available and how much they cost?

I'm going to be replacing my forks sooner or later, so may just do the seals and oil and leave the springs as they are.

Not sure of KR prices but RGV Genuines are about £100 per spring whereas a hyperpro kit is about £99 for the pair and Hagon even cheaper making them less than half price. You can save on springs as they are just a spring, however don't scrimp on oil and seals. Use good brands, preffereably genuine seals or seals you know others use with no issues. There is some real crap pattern stuff out there as well as some good.

The frustrating thing about pattern is quality can vary and and you don't find the problem until it's all back together costing you all that time and new oil.

No point re-sealing if the chrome sliders are chipped though. You'll need that re-coating or grinding if not too bad.

If you do the forks properly now you may be able to sell them as fully serviced and get a better price for them.

I'll probably end up keeping them as they are perfectly good forks, despite the springs being at their service limit.

I'm probably going to buy and knackered RGV and break it for spares, fitting the bits I want to my KR and selling the rest off on eBay.

I am sure some of the guys here on the forum could comment on the quality?

Cheers,

Understanding what progressive springs are. Were the standard springs not progressive? If I took a photo of my current springs, would you be able to tell if they are standard?

the original's certainly aren't lineair. can't remember out of my head if they are full-progressive, or "twice-lineair" (meaning a "combination off 2 lineair springs into one spring").

Progressive are much tighter wound at one end so the spring becomes harder as coils become bound. Easy to spot.

I think off hand, mine are tighter wound at both ends, but I'll upload a picture when I get in.

As they were not past their service limit, I changed the seals and reassembled them with these springs.

They feel worlds different to what they were, probably mainly because of the oil.
