I have a pair of 25.5 Hoji Free boot and one of the straps is on it's last legs. Would either the 23.5-24.5 or 29.5-31.5 work?
Cinched up, there's about 4" of the strap end loose past the cam so it seems like the smaller size should be OK? Or is the longer one safer and just cut the loose end down?
I assume the thicker side that says "Dynafit" also gets longer with the larger sizes? So the larger size may wrap around too far?

Andrew, With an extra 4" of strap, the size 23-24.5 should work fine.

If possible, I wanted a ratchet-style power strap from my Dynafit Radical Pro boots. I was looking specifically at either Hoji Pro Tour or Power Free straps. And wanted to know which would provide a better all-around performance.

Hi Noah,
Either will work fine, and you'll be able to incorporate them into the Hoji Lock. Performance wise, they're both pretty much static so I wouldn't expect to see a noticeable difference.

Hi I was wondering what size of the hoji free power strap I should get for the 26.5 shell? Doesn’t seem like you have that size for either the pro tour or hoji free. Thanks!

Hello Severin, Depends on your fit in the cuff of your boot. If you have a thin leg, you could go a size smaller. If you fill out the boot and don't have much overlap on the strap, go up a size.

I needed to get replacement power straps for my Dynafit TLT Speedfit Pros and the mounting holes on the boots measure about 8.5cm center-to-center. Is the TLT Speedfit Power Straps 23.0-24.5 x2 ($14.95) the right choice? There is a picture on the product page of the hole measurements and it looks to be about 6.75 - 7cm from center-to-center.

Curtis, The TLT Speedfit power strap on the site has only 1 hole as pictured. You will have to poke holes in there to fit your boot. The TLT 7 and 8 have a shorter pattern as you stated, so don't get those. It is for size 23-24 boots, could work for a 25. If you have a bigger boot, get the 29-30.

Howdy Skimo - would the TLT 7 strap fit and replace the velcro strap of the La Sportiva Skorpius CRII? Much appreciated your advice!
4/10/2023
Hi Doug, the TLT8 Carbonio Straps are a better fit, they're a little skinnier and match the width of the stock Skorpius CR II strap. The Skorpius strap might be a little work to remove due to a plastic centering piece sewn onto the back, but once it's out, the new strap should slide right into the same slots on the back.

would a tlt7 (or any other one) fit on a garmont boot? my kenai velcro straps are worn out...they have a 2 hole mounting pattern spaced 2 3/8" apart. the total strap length would have to be ~18"

Hey Koby, the 26.0-28.5 TLT7 strap is ~21.5" long (total length) with the holes spaced ~2.5". So, sounds like it could be an option!

Can I replace the Radical Pro power strap with Hoji Free power strap? I really dislike the velcro on my Radical Pro.

Hi zzz, the Hoji straps are integrated with the Hoji lock system and probably wouldn't be the best bet for a retrofit.

Note the TLT6 Performance CR has two bolt holes, not one as the info says at top. maybe the TLT6 Mountain CR has one hole and that is what is being referred to

The Speedfit strap looks promising as a replacement for the velcro strap on my Zzero 4C. Same 30 mm width and single rivet hole. The Zzero strap is about 22" long (on 30.5), can be made quite slack for climbing. Any reason it wouldn't work well or is there a more equivalent replacement?
Thanks!
Thanks!

Hey Neil, I measured the 30.5 Speedfit power strap at 21.5", so it may have less adjustability to slacken when you are in walk mode. Otherwise, it sounds like a reasonable replacement!

I just purchased the PDG 2 power straps and just curious what tool you use to install the rivets? Any guidance would be greatly appreciated! Thanks Guys you are killing it on BC Gear!
12/29/2021
Hey Alex, Dynafit actually uses a full-on rivet press to install those, which is what we use as well. For installing them at home, I would use either some generic nut+bolt combo or use a couple 1/4in Chicago rivets.

I have 27.5 TLT7s that came without a power strap and want to add one. I see you don't have the exact size for TLT7s. My calves are a little skinny. Would you size down to the 22.5-25.5 range, or could I use the correct size for TLT8s? What would you recommend?

Hey Sam, thanks for reaching out! I'd recommend getting the TLT8 power strap in the 26.0-28.5.

Can I use the TLT Speedfit powerstrap for my TLT6s instead of trying to get the TLT7 straps to work, as suggested in the description? Looks like the Speedfit straps have just one hole each.
Is it the same mechanism?

Would these work on Fischer Travers?

These wouldn't function quite the same as the stock power strap/buckle combo on that boot, but send us a message at "help@skimo.co" and let us know which size boot you have and if it is left or right. We'll see if we have any parts that'll work!

I'm looking for a cam style power strap to replace the velcro strap on my la sportiva skorpius boots. I was originally thinking TLT7 but it looks like the speed fit strap doesnt have any grommets in it (which would be preferred). Is this accurate? Also is it made of a similar material to the TLT7 strap with no stretch? Thanks!
1/6/2021
Hi Jeremy, yes that's accurate on both counts. You likely wouldn't be able to use a grommet anyhow as it wouldn't line up. Works fine without.

Is it possible to replace an Arc'teryx Procline Carbon power strap with a Dynafit model? My boots are a size 26, and I would like to add a hefiter, stiffer strap. Any info would help. Thank you!
9/22/2020
Hey John, the dynafit power straps aren't going to be any stiffer than the one on the Arc'teryx Procline Carbon, the only difference between them is that the strap on the Arc'teryx is a little wider across the shin. The holes in the straps are in different places, so though it is doable to swap them if you poke some new holes in the dynafit strap, it will take a little work and may wear out over time. If you're looking for a more elastic strap that you can really cinche down your best bet will be to get some booster straps.

Hi there,
My Hoji power straps are bottoming out because they are too long for my skinny ankles. Will sizing down on a pair of replacement straps help this?

Hey Ben, yes, you could definitely size down with the power strap to get a tighter fit! The other option would be to set your strap a screw-hole shorter than the stock two-hole connection (though in this setting you might still run out of strap).

What width are these power straps? I need to replace the straps on my Scarpa T1 telemark boots. The original straps are 1.25 inches wide. The strap has to fit through a plastic piece so if your straps are wider than that I don't know it they would work. Thanks.

John, I just measure the TLT 7 power strap and it comes in at 1.25 inches. So it should work fine. The TLT 8 power straps measure right at 1 inch.

Hi guys. I'm looking to add TLT 7 power straps to my size 29.0 Scarpa Alien RS boots (per Brian H.'s helpful blog). What size straps should I get? I have skinny calves and like to crank down on power straps. I am not sure if the Dynafit size 29.0 - 30.5 straps will be too long, if their cuff sizing is not comparable to Scarpa's, if that makes sense. Thanks.
1/31/2020
Hey Jim, good call on the power strap addition! You will find the 29.0-30.5 TLT powerstraps to be about the right diameter, but if you want to crank down on the straps more, the 26.0-28.5 may work even better. Happy modding.
