3T Arx Pro Road Bike Stem
3T's race-proven design for the perfect connection between fork and handlebar, and suited to all cycling disciplines. Clamp design is optimized to ensure a secure fit on composite steerers and bars without the need for potentially damaging high torque values during assembly. 3T inhouse tests show Arx's clamp by far exceeds the CEN standard, and also that it works very well with other brands of handlebar.

Great stem, works well with my new 3T bars, quite stiff and not too heavy, I prefer the older double bolt system purely for peace of mind. At the price I paid I'm well happy!!
I would consider this to be a high quality aluminum stem. Superb finish on product. I bought it because I needed a shorter stem. Chose this stem because of brand recognition and solid reviews. First purchase from Merlin Cycles. Good price, but a little longer than normal ship time coming from overseas. I would purchase from them again.
Have ridden this stem for many years, on track and road. No problems with it whatsoever.
The Arx Pro stems are a great addition to your bike and these earlier models are getting much harder to find. I like these better than the more recent Arx2 stems as the front bolts are spaced a little further apart and appear to grip the bars more solidly.
