(although I'm not actually sure if that's right, is 50% the spring considered unsprung?) - It's an inaccurate estimation i'll admit, but the weight is split between both. How exact is dependent on the mounting location. It is unquestionably closer to 50/50 than 20/80 though


As for an old vs new spring the spring on my bike was only one season old and had about 1-2 turns of preload (which in less than 1/16 and in on this shock) and unlike a vehicle there is no load on them without a rider (the rider is the main mass - arguable) so as for it being fatigued after only one season and being my dedicated dh bike it only sees about 6-8 trips a season so I highly doubt it was fatigued when I changed to the alloy spring.

The last part is still very debatable. Some companies are claiming that TI alloy springs have a cycling lifetime 50% greater than chrome silicone and vanadium steel. And even 6-8 rides is a long time. Sag can set in within weeks if not days of riding. Not to mention, even brand new cars/bikes already have several thousand oscillations before you even buy it.

Also i'm still not understanding your logic on your preloading methods. But if it works i have no qualms lol :tiphat:

Not sure how it's arguable that the rider is the main mass when the bike weighs 36lbs and sits at zero sag without rider.

36LBS with a coil spring? What kind of slacked out gnarliness are you riding?

You asking what bike? It's a 2011 Santa Cruz v10 carbon (before they had the carbon swing arm though so it weighs a little more). A large chunk is the damn dh casing tires and if it weren't for a handful of super rocky trails at northstar I could get away with a mid casing but the last time I tried I ruined the tire and then destroyed the rim. I think it's maybe less than 36 though but can't remember last time I weighed it somewhere just below 36. Other bike is the new Nomad 4 but that's air sprung so no coil spring debate on that one.

Very nice! How are you liking the new nomad? I haven't had a chance to throw a leg over a SC but I hear their quality is top notch. Never tried a coil either for that matter. I'm currently on a transition scout , its really fun for the moderate east coast stuff around me.

Out of curiosity jhill. Do you ride professionally? That seems like a crazy amount of money for entertainment purposes.

Mountain bikes can be $$$$$$. :eek: I got over $3,000 in one. Get into time trials or something like that. The frames alone can be over $7,000. Then add another $4,000 on top of that. :eek: :shakes head:

I know, that's why i was wandering if it was for competition use. Spending that much for entertainment usage seems crazy if you aren't getting paid to do it. 3k is the most i'd spend.

I've got a lot of $$$$$ into my road bike. Carbon fiber is expensive. :icon17:

It's an expensive rabbit hole to go down. Sucks you right in. I have more in my bicycle than I paid for a new yz250f :ugh2:

After getting into mountain bikes, things like $4k volk's don't scare me away anymore. Probably not a good thing :icon17:

I'd agree to that. All rabbit holes are expensive. The question is how worth it is falling into it lol. With cars, motorcycles and houses the gains seem longer lasting in some cases. I just can't wrap my head around spending that much on a bike that requires human power to work lol.

Not professional just my main hobby. Before I left the auto field I could not afford a nice car and to really enjoy the z you have to pay for a track day which adds up real quick. My bike is free to ride anywhere, anytime. So always had a cheap car and expensive bike, plus I had been in the bike industry and kept contacts so I got them for much less $$$.

Also mass think of it like this 8k gets you the f1 of bikes that are no different than what the pros get to enjoy. Now how expensive is an f1 car in comparison?

Not having ridden a transition I can't say how it compares but I'll say the nomad 4 is amazing in every way. Coming off a nomad two this thing climbs better than the nomad two and descends just like my v10. It truly is an amazing bike and if it weren't for my v10 being a 26" which holds next to no value today I could probably sell the v10 and really not miss it at the parks which I could not say about the nomad 2.

Coil vs air depends a lot on the bikes leverage ratio, there really isn't one is better than the other, don't get caught into the coil hype that's going on right now. A coil shock on the right bike is amazing but a coil shock on the wrong bike is equally crap.

A F1 car can go over 200mph and pull 5g's through a corner at over 120mph.

apples and oranges :tup:
