Spx 15 mounting

[arild]

So, despite a pending divorce in about nine months, and the financial crap associated with that, the rossi site has a sale, and I had to buy really cheap ($200ish) forza SPX15s. Partly because I've run out of pivots and STH16 Steels, partly because getting into pivots in deep snow really is a pita.

So, does anyone have good templates, or is the spx pattern part of official look jigs? I have the jigarex, would not mind getting plates for it.

The other thing; am I correct in thinking the wc px15/18 brakes will work here? I forgot who did this.

Cheers!

Can’t help with the bindings, but I’m sorry to hear about the divorce. Hopefully it works out for the best.

I mounted a pair of SPX last month. I think the paper template came from here and it worked well: https://github.com/tomahawkins/binding-templates

Toes are the same pattern as pivots, here’s the heels from my jig:

Px heels are not the same pattern as SPX heel pattern.

Yeah, I used my pivot jig for the toes, and the paper template for the heels.

[TAFKALVS]

Are these SPX or SPX race?

[Lord Thomas]

The worm screw adjusted race bindings use a different brake. That said, Look still shows a 120mm brake for the in addition to the 80's that come with the Rockerace's. The spx brakes are much easier to get your hands on

What you need is Look/Rossignol micro heel brakes. They're available in 100mm and 120mm sizes.

Your can also Frankenstein your own setup.

I've been doing a bunch of research on this very topic.

is the spx pattern part of official look jigs?

SPX Race heels are 80mm on center between screws. Standard SPX (shown on zlatham's jig above) is 105mm on center. Check before you poke holes in things.

[arild]

Yeah, forgot to say the ones I've got on the way are Rockeraces, so the heel holes should be a lot more forward than that of the jig. Thanks for the links!

Thanks dude, all is well, except for the financial bit(not suffering in any way, shape or form, though).

Arlid,
This is a database that has paper templates for Rockerace clamps by bsl. I've used it for test mounts but not on skis. That is going to change about a week from now when I put some 15's on my super comp rc85's. If you try this before I do let me know how it works.

LT, you'll probably get there before me. I'm waiting on some rc85comps, they'll be here in a couple of weeks.

Ok, now I’m a bit confused as to which heels you actually have, but for what it’s worth the Jigarex pivot plate also has the regular SPX heel pattern included on it.

[Lord Thomas]

The Rockerace is Looks race binding that was developed solely for mounting to a race plate and has a different hole pattern than the SPX and pivot (slightly different brake as well). It's actually the best of both the spx and pivot and should be at the top of most peoples list. Also works mounted flat to a ski. No idea why it's not more popular here than it is. I'm slowly converting everything to rockerace

Wait, what?. Maybe I need more coffee....This thread got me wondering about the layout I have for the SPX/NX. This is what I have vs the 80mm for the SPX race, correct?:

[McShortyShorts]

I think I asked this on Pugski a while back, but has anyone tried to put a SPX 15/18 rockerace heelpiece on a SPX 12 heel track? If they're swappable that would solve mount pattern issues and wide brake availability

[ZomblibulaX]

You got it right, Terry. Look's standard pivot/axial jig has holes for px/spx heels (105mm) and nx demo heels (130mm and all but defunct). But since the spacing differences are all 25mm, it's super easy to spot the rear holes at 105, then close the jig up 25mm and drill the rear holes at 80mm for the race binders.

The rockerace though is much shorter, can't remember off the top of my head but I think 45mm? Don't quote me on that.

[ZomblibulaX]

LT, you experience any durability issues running the rockerace without a plate? I can't imagine I'm going to break it if the world cuppers are skiing tech on the damn things, but Look still says it's verboten to mount flat.

[Lord Thomas]

McShorty - NO, they are not interchangeable. The SPX is adjusted for length/bsl with a tab and the rockerace is a worm drive. But the actual heel design and function is the same. I've got pictures of both side by side but the fucking website won't let me upload pics right now.

ZombX - I can't speak to durability from personal use but the actual heel is functionally the same as the spx. So in that respect they are well tested in the real world. Also, these are the same bindings they have been using on race skis for a long time and given how many worldcup victories they've racked up have demonstrated how well they work in extreme use cases. Rockerace is the same binding as an spx but with a better mechanism for bsl adjustment and on a mounting plate with a small footprint like a pivot. Toes are exactly the same as pivots

[Island Bay]

Very sorry to hear, Arild. And no binding advice, I’m afraid .

[McDee]

So all SPX Bindings with Rockerace in the name will have the wormscrew?

[EWG]

LT - I think the reason so few of us use rockerrace is the combo of the plate requirement (on paper) and the lack of wide brakes. Have we solved the brake width issue?

[Lord Thomas]

EWG, yeah, I think you pretty much nailed it. Look markets it solely as a race clamp for plates. McDee, yes. Rockerace is the wormscrew adjustment and totally different mount pattern (actually, I'm not certain of this but I think two of the holes for rockerace and spx may align but not sure how they relate for bsl)

As far as I'm concerned the lack of brakes is the biggest holdup on rockerace. There used to be 100's but now it's only 80's and 120's in the catalog, that I'm aware of. That said, there is a thread over at skitalk that give a step by step for swapping spx arms, of any width, into the rockerace housing. Looks like a little bit of a pain but doable.
