I've had my Kink Cross Bolt stem for about 6 moths now and I must say it is extremely durable for what price it is. The only downside of it is that it is on the heavier side but it sure can take a beating. The bolts stay tite, my bars havnt slipped at all scince ive had it. Overall im impressed with its performance and I would recommend(sp) getting this stem.

Costs: about $39 USD
