Scarpa Rebel Pro GTX crampon question

I picked up a new pair of boots, and my crampons don't seem to fit well to them. I was wondering for those of you who own a pair of Rebel pro gtx boots if you needed a smaller toe bail and or an asymmetrical crampon bar to get a really well dialed in fit?

I have the Rebels and the Bladeruuners (size 1). They fit great. No offsetting the toe bail.

Which size do you have?

43.5 or 10.33 US. The crampon in question is a Black Diamond Cyborg Pro

I had no problems with my 45.5 Rebels and cyborgs..

No offset toe bail

The toe tends to wobble on mine. I.e. from side to side. Maybe I don't have them adjusted correctly yet. Thanks for that should be pretty similar I would think that's not a huge difference in size.

How old are your crampons? BD sells a narrow bail for the Stinger.

Fairly new. I've heard they have a narrow bail, I might go that route.

Just tighten the micro adjustment on your crampons!!! If I can get it you can get a good tight fit. You don't need a narrow bail.

Got the same setup and went with the smaller bail. It's a much better, more secure fit.

While I don't have the Rebels I do wear a very low profile boot (Vasque M-Possible SS, it was a great boot but hasn't been made for years). These boots are size 8 men's, so they're not a rinky-dinky size either.

In my experience it's been difficult to find a crampon that I'm happy with the fit on these boots. Hated the Cyborgs, but I had them so I wore them for a couple of seasons. Could never get the fit right and the heel dial would always back off leaving a loose crampon.

I have also worn my husbands G14s. Nice Crampon, but felt bulky on my boot.

Just got a set of Petzl Lynx and good stuff so far. Hopefully I'll still be happy with them by the end of the season. They also have an asymmetrical fit do they might be a good option for your Rebels? Good luck!

It definitely takes an acute angled toe bail to fit the Rebel Pro GTX's narrow front welt. Dane's discussed the BD toe bail fit issue quite a bit, especially relevant for boots like these. I think he usually ends up replacing them with narrower Petzl bails. (Yup, just checked and that's what he does: coldthistle.blogspot.com/20…)

I have the Rebel Ultra GTX and a Petzl Lynx crampon. They fit together very well as the Lynx has a narrow bail. However, I have to be careful even with the Lynx to make sure I get ideal alignment.

Good luck. Get it right - there are big dividends to a good crampon fit!

Dane's review is dated at best relative to BD's new bail. Frankly, Dane could have gotten a better fit if he had reversed the link bars. The Asymmetrical shape of the boot has a greater impact on the crampon fit than the width of the bail.

I've had success squishing the two bail in a vice. Leave it on the crampon on and tighten the vice on the corners of the bail. Check the fit and repeat until it's fits your tow better. Cheap and effective.

So I tried the set up of Rebel Pro + Cyborg Small front bail out at the ice park and while it works it is not ideal. The crampon tends to slide laterally toward the outer edge of the toe bail. For whatever reason, the fit is just not that great. I suppose I will try putting it in a vise as suggested.

I'll email you a video of myself fitting the Cyborgs onto my Rebels.

PM me and maybe we could figure it out!

Sounds good. I'll send you a picture of what I'm describing.

Did you flip the link bar over?

No. I guess I don't understand why flipping the link bar will help, it appears to be the same for both crampons, and even stamped with the same marking so that it is universal to both sides. At least as far as I can tell.

I have the rear heal lever set so it cramps plenty firm, the fit is ok, but it moves sideways after I climb on it. Below is a picture.

I borrowed a pair of Petzl Lynx tonight, the front and secondary point on the cyborg is better positioned on the boot but the asymmetrical alignment of the lynx is better at least at this boot size.

The boot isn't straight so the curved link bar causes the crampons to point inward. By extension, the toe of the boot slides outward in the bail. Flipping the bar over causes some interference in the crampon assembly and keeps the points (and toe in the bail) pointing straight.

Like this: Left boot, right bar. Right boot, left bar.

See how the crampons look straight? They can't physically turn inward because the bars curve outward.

Edit: Also, the toe bail safety strap causes alignment issues. You can remove it without sacrificing safety and improve crampon fit.

Ray,

Forgive me here, but since the boot is so asymmetrical wouldn't I want a crampon that more followed in line with the overall shape of the boot? It seems that this more or less straightens out the crampon, and I'm attempting to fit a straight object to a curved profile... I will try it none the less and give you some feedback.

Thanks

I've got a pair of 44 Rebel pros and the cyborgs. I've got them setup with the small bails and the BD asymmetric bars. The right toe will shift over a day and I'd be hesitant to use it without the wire keeper, but I've climbed a lot of ice and rock with them and had no issues. The right shifts because the toe welt is a good few mm's smaller than the left welt.
