Update for all!
My new and improved bar is looking better than ever. I took it out this morning for a run and what an achievement. This bar is truly one of the best bars i have ever ridden. Such a light feel when your holding the bar but yet very strong.
Specs:
Length: 48cm (perfect for my 9m rebel)
Weight: 334grams including lines on the bar.
Material: 100% carbon cloth
Grip: Tennis tape (bought from local fitness shop)
Strength: Capable of up to 40knot gusts. (I'm 83kg)
BTW the below picture is not my bar however mine is very similar. I have not put a swivel on my bar as it keeps it nice and light. I observed that when I was drilling the holes through the bar for the main de-power line/ turning lines that it lost about 40% of its initial strength however being carbon it is still incredibly strong and durable.
Im yet to make a 54cm bar for my 12m and 15m.
