Fritschi Diamir — Evo and Vipec Heel Comparison

Post by blogger | February 14, 2018

Someone asked. Evo and Vipec ski touring binding heels are more similar than different. They have virtually the same vertical elasticity (very little, same as other classic tech bindings), similar heel lifts, and the same pin height above ski. A few photos. I did not do a tear down for fear of ruining my functional set of Evos, we’ll perhaps do that during summer. Though I’m not sure a teardown is necessary. Any questions, ask away.

Evo (left) heel weighs 204 grams, Vipec (right) is 212.

Pin heights are the same.

Pin heights are the same.

Vertical release is accomplished by the pins spreading apart as the boot heel fitting is pulled up.

Vertical release is accomplished by the pins spreading apart as the boot heel fitting is pulled up. Evo pins move exactly left-right while the Vipec pins are on rotating arms and actually might contribute a fraction of a millimeter to vertical elastic travel. Fritschi probably had good reasons for this change, but interesting that Evo goes back to fully “classic” tech binding heel release design.

Both bindings have good boot length range, as well as ski flex compensation.

Both bindings have good boot length range, as well as ski flex compensation. The Vipec boot length adjustment range is about 3 cm, with Evo giving about 3.5 — there is a bit of a judgment call on how far back you can move the heel unit for boot length adjustment, for larger more aggressive skiers I don’t like to set as far back as possible. To clarify, while mounting this sort of binding you can use the “standard” settings of a mounting jig or template, or mess around with setting the boot length adjustment so it’s biased forward or back (by changing the actual physical mounting position of the heel unit track). I prefer to analyse what appears to the be the strongest position for the heel unit, and bias the mount so the binding heel ends up in that general area on the adjustment track.

Medium lifters fold down over pins.

High lifters, same, both Evo and Vipec lifters are equal in height.

View from rear, big change is location of tension adjustment screw.

View from rear, big change is location of tension adjustment screw (upper screw in Evo to left). This has to do with the type of mechanicals create resistance for the pins, clearly this is the biggest change.

Top view, spot the adjustment screw on Vipec, not on top of Evo.

Top view, spot the adjustment screw on Vipec, not on top of Evo. From what I’ve seen, both types of heel units work well for ski touring so long as latest bug-free versions are used, but I’m guessing Fritschi had good reasons for the Evo changes, and I’d recommend that over the Vipec.

Not much else. The huge difference is of course between Vipec/Evo and Tecton. I’m not sure a comparo in that regard is appropriate, too much apples to oranges. Tecton heel is almost entirely and strongly different in that it does not have pins, and is not a “classic” tech binding heel of any sort.

    So I have first gen heel and second gen toe Vipecs – and a few times i didn’t fully engage my heel forward and it slips back as I start my run. All the sudden i’m free heeling and Ii need to stop and adjust. Though it has never happened when i’m dropping in something with an X or a R factor i’m 100% worried that it will.

    Have the new gen heels done anything to address this?

    Thanks Lou,

    Agreed – same binding with subtle differences. But you could say the same from Gen1 to Gen2 toes and the same for the next iteration and soforth.

    I would be curious as to why they changed the mechanicals for how the pins move and the same for the inner workings for the mechanicals controlling release. You know…the important stuff like if it makes a difference in how they release, consistency of release, safety of release….and weight? Hell it may have been a simplification of manufacturing. BUT – they work and from what I have seen as they have moved through their progression of the original to the EVO, each changed model has been an improvement over the previous. I’ve found them reliable and less harsh to ski over other tech bindings. Especially with some of the more firm conditions here in VT.

    Its pretty easy to geek out on this stuff when the touring is less than ideal in your back yard. Speaking of…. I need to get my behind out there now.

    Thanks again for your reporting Lou!

    Andrew, LOL thanks for pointing that out. My mistake. I usually do everything perfectly, but once every couple of years something falls through the cracks.

    Gabe, I’m told there was a defect that resulted in the heel unit going rearward off the boot length adjustment track, I also was told this might have been something to do with the touring/alpine heel change mechanism. In any case, I don’t think the earlier Vipecs were very viable, considering that as well as the problems they had with the toe pins, not to mention the difficult boot entry a lot of people experienced. We like the Vipec Black and the Evo. Tecton seems to be working out nicely as well, though we’d prefer to see that brake part beefed up.

    In any case, if you have a Vipec that the heel unit fails on, that needs to be returned on warranty or otherwise replaced. Ridiculous and dangerous to be skiing on such.

    Lou, I’m curious about one of the statements you made here:

    “for larger more aggressive skiers I don’t like to set as far back as possible.” Does the closer fit provide more heel retention? Should it be set closer than the Dynafit spacer (ie a worn down nickle?). Thanks!

  6. Lou Dawson 2 February 15th, 2018 6:30 am

    Phil, I was talking about location of heel unit on the boot length adjustment track, this can be biased when the binding is mounted, after that it’s always the same for a given length boot. Sorry to confuse, I’ll edit. Lou

    Edited, see above.

  7. Ryan February 15th, 2018 10:22 am

    Huh – optical illusion or…? The new pins appear to be shorter in the pictures. Not protruding into the boot fittings as far?

  8. Lou Dawson 2 February 15th, 2018 10:29 am

    Same length.

  9. Ryan February 15th, 2018 10:34 am

    Thanks again!

    From the Nobody-is-likely-to-care Department, I’ll add that the brake assembly process for the Evo is much more intricate and puzzle-like than any brake I’ve ever put together. Step in mech seems much more refined than gen one Vipec.

  11. JP February 17th, 2018 3:44 pm

    EVO. Brake assembly is different. 2nd tier lifter is stiffer material, and when engaged in climbing mode is firmer laterally. The housing at the back is slimmer and longer with the DIN spring horizontal, not vertical. The boot sits on a ledge and the pin assembly is different. The EVO is very different than the Black and earlier versions

  12. Ryan February 17th, 2018 4:13 pm

    Thanks JP…

    Any thoughts as to what it changes in function. Safer release, more elasticity, durability?

  13. Shawn February 20th, 2018 11:12 am

    Kinda on topic and apologies of already addressed elsewhere but could not find definitive answer. My understanding was no tech gap with the vipec. Was told by BD there should be a 5mm gap. What should it be? Tks Lou. Cheers.

  14. Lou Dawson 2 February 20th, 2018 2:24 pm

    Shawn, try site search for keyword “Vipec” it’ll lead you to this and other things:

    Vipec is supposed to have kiss gap.


  15. pete February 25th, 2018 3:08 am

    gabe: is this the issue of snow working itself into the heel? If so it is pretty easily remedied, even though potentially having to screw off the heel to get the snow out is a giant hassle.

    Apparently the tecton is getting an update for next year(?). Any info Lou?

  16. Lawrence August 17th, 2018 10:25 pm

    Lou, I have the vipec 12 black binding. Sending the front toe pieces in for warranty. They need to send me back the evo toes. Do you think they will be OK with the vipec 12 heels?

  17. Lou Dawson 2 August 18th, 2018 8:43 am

    Hi Lawrence, I can’t think of any reason why Evo toe woudn’t function with Vipec heel. But always bench test. Lou
