surfnsnow Posted March 8, 2009 Report Share Posted March 8, 2009 I'm thinking about buying BTS springs for my Raichle AF 600s and am interested in input from those who may have already purchased them. I'm thinking about going soft (yellow) on the toeside and medium (blue) on the heelside. A few facts about myself and skill level may help with any feedback: (1) I weigh 165 lbs; (2) I ride an f2 Silberpfeil 80% of the time with my f2 Speedster coming out of the quiver on those true hardpack days; (3) While I'd like to say I'm in the advanced category of carvers :), intermediate would be more truthful; (4) I've got my Raichles set with forward flex and no heelside flex. Any and all input would be appreciated. Good turns! Quote Link to comment Share on other sites More sharing options...
Jack M Posted March 8, 2009 Report Share Posted March 8, 2009 go yellow/yellow. Quote Link to comment Share on other sites More sharing options...
jp1 Posted March 8, 2009 Report Share Posted March 8, 2009 Got them (Blue/Blue) them, but want to try yellow/yellow. Keep in mind the spring rates within the same color (according to chart) are more than doubled on the heel already. The BTS are a 'steal' at the Sale Price.

I didn't realize the rear spring had double the tension of the front. This would almost automatically cover the fact that I like more stiffness on my heelside. I'm going to dig around on the web site to try to find that chart. Quote Link to comment Share on other sites More sharing options...
Corey Posted March 8, 2009 Report Share Posted March 8, 2009 I'm going to dig around on the web site to try to find that chart. BTS spring rates are at the bottom of this page: http://www.bomberonline.com/store/boots/BTS_kit.cfm Quote Link to comment Share on other sites More sharing options...
bobdea Posted March 8, 2009 Report Share Posted March 8, 2009 king crimson is on blue in that boot. IMO yellow might be good or might not, blue is a safer bet. it would be more supple than the locked boot but would not be super loose. I have seen a couple people with yellow springs and they put a ton of pre-load on them, negates the point of a softer spring. I ride the 700s with blue springs, I'm a lot heavier though.

surfnsnow Posted March 8, 2009 Author Report Share Posted March 8, 2009 go yellow/yellow. Jack, You answered yellow/yellow, but a lot of the feedback seems to lean toward the blue springs. I'm just wondering what your rational is for the yellow. My weight? Or? Thanks... Quote Link to comment Share on other sites More sharing options...
jp1 Posted March 8, 2009 Report Share Posted March 8, 2009 Here's the Specs, copied from BTS page: Technical Data Long (toe side) springs = 3" (7.62cm) long Short (heel side) springs = 1.5" (3.9cm) long Spring Rates: units = lbs/in (N/mm) Yellow "Long" Spring = 96 (25) Yellow "Short" Spring = 200 (56) Blue "Long" Spring = 144 (60) Blue "Short" Spring = 320 (129) Red "Long" Spring = 340 (82) Red "Short" Spring = 656 (177) Pay attention to the numbers though...

Fastskiguy Posted March 9, 2009 Report Share Posted March 9, 2009 I didn't think it mattered if you ran one color for the back and one for the front....I know the spring is softer (duh) but when you crank it against the stiffer spring it compresses and is, well, more firm.
