Derailleur Hanger for Trek 172

Well, you never know if a cheap part will be decent. In this case I feel confident that it is the same part that came on the bike from Trek. It had the exact same part number stamp. Okay, that could have been copied, but I'd be surprised if anyone cared to copy a part like this down to that level of detail.

Much cheaper from Amazon than the manufacturers and bike catalogs.

Pretty much a perfect fit for the stock rear derailleur on an allant 8s

Thanks to the seller this product fit exactly like the old one

The product was exactly as advertised and came quickly.

Super

Received the right part. How ever i believe this pieces the factory price is too high. And here found it for a cheaper price. I save around 8 dollars. I believe this piece should cost no more than 10 dollars. The way i look at is like this a brand new rim costs 45 dollars, a rim has more labor, more metal and only cost teice than this piece. Anyway i needed it.

I've been bicycling my whole life, but never broke a hanger before this. I'm glad I received it quickly and that it was easy to install
