Most durable kite bar and lines

Postby toddsphresh » Tue Sep 26, 2017 10:32 am

Looking to replace my tired 2008 flexifoil bar. Don't care the year or options just looking for a bar that I wont have to worry about breaking anytime soon that has the least maintenance. Something for those nuking 30+ knot days. Thanks for any and all advice

For lines, nothing gets even close to Q-Power. My 3 years old regular Q-power set looks brand new. I had a 10 year old set of Q-Power pro that I stopped using because come on, 10 years... but it looked flawless.

For bars, I'm very happy with the old switch bar version 2, holding on really well after maybe 4 years?. I like the slightly bigger diameter and tough rubber grip.

Why aren't there any manufacturers ussing Q-Line? And it's a US only thing or what? I don't think there's a single shop in the Netherlands selling that stuff.

+1 For the Switch V2-V3 bar. Not the prettiest, and pretty heavy, but indestructible. And spareparts readily available, so maybe you can alter your current bar with Switch components :)

A shop I do work for had Q-Power line until they said that we did not sell enough and dropped us. Now I use Jerry Brown braided lines in custom made line sets. Although my stretching techniques have evolved much beyond what I did with Q-Power line, I firmly believe the Jerry Brown linesets are the best for feel and durability. And I am much happier with Jerry Brown as opposed to Q-Power line.

Q-power has some issues that you need to know about.

1. It does stretch. If you use knots, it will stretch at those knots as they "set". But pre-stretching is important just like braid, for the entire length of the line. All Spectra/Dyneema stretches elastically and also has some yield. With braid, you need to set the braid AND stretch. With Q-Power line, you do not have to set any braid, but you must stretch the core to eliminate it's yield.
2. If you sleeve and sew loops on the ends with a sewing machine, wet the Q-Power line first. This will stop the needle and nylon thread from cutting (melting) the Q-Power line during the sewing operation. If you do not wet, you can lose up to 75% of the strength of the line as strands are cut by the sewing action. Some of this high loss has to do with the linear layup of the internal load bearing core of Q-power. Braids (thus non linear) tend to make up for some strands being cut at different locations along the line.
3. There have been reports of kiters doing testing with Q-Power line knotted {figure 8} connections resulting in a 60% (reduction to around 250lb) in tensile strength loss at the not. That means that your front line sets may have good low elastic stretch properties, but ultimate strength is compromised below what any kiter would want to know about.


Number 3 may be why no MFG is using Q-Power line with their bars.

I will say that Q-Power line can be the most useful thing in your tool box though. It makes super quick knotted pigtails. And given that you are connecting above the knot onto two lines, that 250lb breaking strength should be increased to at least 500lb or more when used with a "larks head" connection (pigtail) as in the pic below.

Liros DC series is perfectly fine for most riders and you can splice it so it works well with flag out systems. Q power line cannot be spliced.

I suddenly recall a brand using new sheathed lines... can't remember which one though :')

Yeah, that's the one!

Is that the same idea as Q-Power?
