I got a bit bored of my echo SL brake, and wanted to try something different. Picked up one of these carbon fiber levers from RB. I can't believe how powerful these levers are!
One downside however, is that you need to keep the brake pads really close to the rim. This is because the ratio of movement between the lever blade and the pad is higher. It takes a lot more lever movement to move the pads the same distance, when compared to standard magura or echo levers. This is probably why the brake is more powerful though.
If your wheel often goes out of true, this is not the brake lever for you. Otherwise, if you're looking for a little more power, you can give these a try.
I'm not sure who sells them in taiwan, but you can get them from www.thetrialsinshop.com. I'm sure they'll have no problem mailing the lever to taiwan:)
