“I had two Magene Exar Ultralight TPU tubes as spares and had to use them when I unfortunately encountered some glass on a ride which punctured my existing TPU tube. I removed the glass from the tyre and installed the tube with no problems only to have a slow deflation of the same tyre a short time later.
On inspection it was found that the leak was from the base of the valve stem and not from left over glass or installation issue. I then had to use the second tube which thanfully got me home.
I will be returning the faulty tube to 99 Bikes for a refund as I wwas not impressed with this TPU tube. I will be returning to the standard tubes as I can't justify the extra expenditure of TPU tubes.”
“I went to your store on Oxford St to purchase two inner tubes for my CUBE bicycle that I bought from you. I gave the lady the inner tube that needed replaced. She gave me two tubes of the wrong size. Now I am stuck overseas without the tubes I need to get my bike on the road. Ibought one lightweight and one standard. I will return these when i come back to Australia in about six weeks. The tubes look like they are 4-5cm too large for the rim. This is poor service and small errors can have big consequences.”
“Won't buy these again. The valve stem is too wide to fit inside my floor pump, so I have to use hand pump or CO2. They leak air therefore requiring pumping at least twice a week, which I understand is normal for TPU. .”
