Thanks to all for the comments & suggestions. Sorry I didn’t respond sooner but I had a lot to digest.
Versy, which Intruder shocks, the VS800 or the VS1400. I suspect the 800. New VS800 shocks run about $700 bucks; eBay has some for very reasonable prices but I’m not too keen on used shock absorbers. I guess ya gotta keep your options open. How long are the Intruder shocks?
Hiko, I googled the White shocks (SA0029014). Looks like I would have to procure those through an outlet in NZ or Aus. The NZ exchange rate makes those a real bargain provided the shipping to Hawaii isn’t too awful expensive. I can’t find any info on the spring rate, length, etc. Do you happen to know what the spring rate is?
Gary, exceedingly good posts on the suspension. My compliments. I have some questions for you.
You set the free sag on the forks at 10mm, which is 8% of the 127mm travel. Is it OK to also set the free sag on the rear shocks to 8% of the travel? For instance, the stock rear wheel travel is exactly 2.69”. That would work out to free sag = .215” (5.5mm), very close to your estimate. Once I replace the rear shocks the wheel travel should increase so I want to know if 8% is a good target.
I’m baffled on the free sag guidance, if less than recommended you need heavier spring, if more than recommended you need a lighter spring. That seems counterintuitive. I saw similar guidance on an Aussie website. I’m missing something. Can you elaborate?
Please tell me if I have the procedure correct. Step 1, determine baseline. Step 2, establish and set correct race sag for given travel. Step 3, check free sag to verify proper spring rate.
Tocsik & Dave, I agree that the belt tension might be a problem and I think Dave’s suggestion to stick with the adjustment established with stock shocks is a good suggestion. I simulated geometry with stock shocks (10.6” eye-to-eye), 11” shocks, 11.5” shocks, and 12” shocks. With 12” suspenders that belt is mighty loose. I don’t know how folks run it with 13” shocks.
Ohiomoto, I tried to get more info on the Hagen shocks. Dime City Cycle seems to sell them, but their website doesn’t provide any specifics. Looks to me like I could probably call them and see what they can provided. Currently, it doesn’t look like they have any 11” or 11.5”, and they have no info on spring rates.
