Hey everyone I am a newbie from Reno NV. Starting my first build using GT Kustom Kruser's Double down. I was planning on taking advantage of the nexis three speed hub by using Sick Bike Part's shift kit but I am haveing trouble finding threads about the product. I also encountered a certificate expiration when ordering so I didn't complete the transaction. Is Sick Bike Parts shift kit a good product? Is it a safe site?
