Venzo Bike Adjustable Braze-On Front Derailleur Adapter Clamp for MTB Road Bicycles - Compatible with Shimano Sram - Silver 34.9mm

I needed this adapter to install a braze-on Shimano Ultegra derailleur to a bike without a brazed fitting. The adapter is well finished, a perfect fit for the size, and accommodated the derailleur perfectly. The curved, slotted derailleur bracket made adjustment a breeze. I actually found it much simpler to adjust than a clamp-on derailleur. A good value. Tigerdog sez: hang it!

If you are running a bike designed for 1x and need a front hanger for anything this one is great. I'm running a K-Edge chain retainer on my Lynskey gravel bike and this was perfect for the job....mounted with no issues and the chain retainer was easy align since the hanger can be positioned where you need. A cost effective solution.

Purchased this because I needed an adapter for a 34.9mm clamp with a braze on derailleur. Worked perfectly, holds tight, and has lots of adjustability. No issues after 500 miles of hilly terrain with lots of front derailleur switching. Tad heavy, but overall a super solid product.

Had to use a rubber gasket to get a snug fit as the clamp was a little loose when initially installed. Otherwise it worked just fine

The product came later than listed on the product description page by several days, but then came a day earlier than stated on "product is running late" notice. This is for a bigger down tube so make sure you measure accurately. I initially ordered a smaller one, my fault. Just be aware that this is not a universal fit and there is very little tolerance.

Works well for the washer with 10speed front derailleurs. Good enough for me.

Allowed me to install and upgrade my front derailleur. Well made and strong.

good quality clamp. looks good. nice adjustment range for the derailleur. fits perfectly on my cannondale.
