Dual Carbides...do they slow you down?

I agree with LB on the Wt transfer completely. :Rockon: :yam:

I am wondering if we have addressed the original problem, "no power off the line"? :?

We are talking wt shift and traction and his reference is to power.
My concern for loss of low end power would be clutching and motor. Could be as simple as belt deflection, ie remove shims from secondary to get back to the normal low end gear ratio.

What do ya think? Since we can't ride today?

I may have mis spoke when I posted....the sled does seem to want o get up and go...HOWEVER in the long haul the sled starts to dog. I replaced the belt and plugs. I truly think the carbides is what slowing her down. My buddy put the same ones on his RX1 2005 and noticed the same decrease in performance.

Soooooo....my next question to you all is about SIMMONS Skis and carbides. Is it truly the way to go? This is only my 2nd year owning a sled ...the RX1 was my first purchase... first sled ever. I ride more on the trails than I do on the lake. Eliminating darting is important to me, as well as control in the corners...as well as be able to have some bragging rights beating other sleds off the line. If SIMMONS is the way to go...where is the best place to purchase..websites? Snow shows? and approx. how much can I expect to pay. THANKS again in advance for all of your help with this topic
 

Ya the Simmons take a little off the top. I did notice too that at 115 on the speedo on a hard pack road that slowing down was best done gradual. Suddenly letting off would cause darting then swerving on the uneven surface of the road as one carbide or another dug in. I tried many different setting could not make it go away. I have no studs in the track so this was a scary kind of thing. Almost lost control. With stock ski's this problem never occured. With studs it wouldn't either. Be forwarned.
 
Yeah, but the stock skis cause the sleds to spontaneously go into barrel rolls at 100+ mph when driving on deep or crusty snow.

Sasquatch... you've got too much ski pressure and are using the stock simmons wearbars. The placement of the carbide on those bars pushes the front of the bar down - if you have any bar front of the pivot pressed down, handling will be compromised. The bar should be DRAGGED ONLY for proper handling. Try shimming the skis and change brands of wearbars.
 
I've got 6" Woody's Doolys on my '05 RX-1 Shorty with 96 studs down the middle. There is no darting, but it does seem that my mileage (15ish) is a bit lower than average. I put the Dooly's on before my first ride, so I can't speak to the added drag, but I believe that there is some. On one particular day, the snow seemed to pack in between the Dooly's and reduce steering/increase drag. I'm considering using the stock ski with a Bergstrom triple point next season or perhaps jumping on the Simmons bandwagon, or maybe just get a fresh set of Dooly's and ride on. I put about 1,600 miles on the sled last year, love it with the exception of the RA cable coming out, should be bringing that in to a Madison area dealer in the next month or so. Anyone in the Madison, WI area have a strong dealer recommendation? Famous last words, but I hope to make this a 10 year sled, or turn it into the second sled down the road, i.e. I am and will continue to pamper my Blue Baby!!
 
I haven't noticed a difference in top end speed with the Simmons. I have seen 132mph on the dream meter with Simmons.

I let BlueDog ride my sled last season because he wanted to see how the Simmons performed since he had the stock skis on his 05 RX-1. When he finished the ride on my sled, I said "I want a pair of Simmons". They are so much better than the stock skis. Use a set of Bergstrom triple point carbides on the inside and stock Simmons carbides on the outside.

Some guys like the C&A Pro skis too. Either way, both skis are much better than stock.
 
My $.02...

My RX-1 has NEVER lifted the skis off the ground upon take-off at any time that I've owned it! But then again, I don't have studs.

Keep in mind that when you pull up on the straps, you are reducing ride quality on small bumps because you are compressing the center spring, therefore taking away potential suspension absorption. Pull them up all the way and you've made an 11.5" travel 9.5" or less, not including when you're sitting on it.

Way ahead of you ski's are shimed bars are new. On flat ice it does not do this only on hardpack roads which are not flat but rather lumpy bumpy. I blame it on the inside and outside carbides biting at different times. Remember this is under deacceleration when engine braking is enough to skid the track a might.

The effect is subbtle but without studs the back end can star to move from side to side and if not corrected will get out of control fast. Been there done that.
 
Simmons aren't dual carbides, they are skis. They have two carbides on the ski. Unlike conventional skis with a single carbide down the center, Simmons Skis have the carbides on the outside of the ski and the ski is concave.

Woody's duallies are twin carbides on a single runner.

Simmons ski's are dual runner concaved dished ski's that Ski_Doo copied or tried to (they did a poor job). They are awesome handling ski's and widen out the front end. Compared to the stock ski's they are way more stable. They make darting all but go away. They float up on top of the snow so running in deep powder is easier ( the stockers just sink).

They are not perfect and have a few drawbacks. In fresh snow they tend to plow a little. They can require more steering effort under hardpack conditions. They can wander or dart on hard pack roads under deaccelaration ( studs in track would null this point )

Overall I would recomend them. The drawbacks are negligable but worth noteing for informations sake.

Everyone that had them on the Manitoba ride liked them.
 
Simmons are about $400 USD. To see how they work, try this link. www.flexi-ski.com/SeeIt.html

You can order direct from Simmons or through your dealer. Matt at the Speedshop also sells them, and since he is on this site a lot, I would suggest you purchase through him.

Adding a set of Simmons is the best aftermartket option for an RX-1 in my opinion. Yes, they do reduce the amount of tippyness because they widen the stance of the front end by about 2.5 inches. I have a set of Simmons on my 03 and my 05 RX-1. I have never experienced darting problems with the ski except when following several riders that also have Simmons. I cannot say enough good things about these skis.

To be fair, many people also use the C&A pro ski. It is has a single keel design with a single runner, but they too are wider enhancing the stabilitiy of the front end.
 
Well , if your not already confused, lets see if I can push you over the edge. On my sled ( 04 Warrior ) I ran the Woody duallys and thought they were great, no hunting , however as has been stated here the drag on the front end was considerable. I was thinking of the Simmons when I bought a used 04 Warrior for my wife with the Simmons . The two set ups were the same as far as the hunting goes ( or actually the lack thereof ) and the duallys were around a hundred dollars and the Simmons around $400.00. The big difference was the front end drag , with the duallys I almost never had to use the brake and my milage was about one-half to one gallon more per tank full / and since we ran the same speed and distance , it was a very fair comparison. Now for the kicker / when the duallys wore out I put on a set of Bergstroms triple carbides with the thick ski savers ,at around $100.00 , and I was EXACTALY equal to the Simmons all the way around. No more drag/ easier to put on the trailer/ same fuel milage/ If you want the best of both worlds do what I did. Also when you call in for the carbides have him send you a set of shims that go under the rubber boot on the ski saddle/ later/ jim-bob
