## Customer Reviews

### ⭐⭐⭐⭐⭐ Great bike
*by D***T on January 5, 2019*

After receiving my well packed bike in a huge box, I went to unpacking it as fast as I could. I found no defects or issues. The bike went together very easily and without problems. After tuning the bike and adjust it for size, I took it for a ride around the block. I was amazed. The bike made no noise while riding at all, unlike my old mtn bike it was replacing. I shifted through the gears and was soon at top speed, what a rush. Braking was good also. My only small complaint is that shifting is a little slow, but other than that, it’s all good. I’m already looking at tommaso bikes for when I want to upgrade to a full road bike in a year or so.

### ⭐⭐⭐⭐⭐ This is the best value and most versatile of all of my 8 bikes!
*by B***. on March 1, 2021*

Wow! What a surprise. This is an outstanding gravel bike for half the price of a Canyon entry-level Grail Trek or Cannondale (and there would be a six month back order) The Shimano Touray group set with a tripple cage is as good, but perhaps heavier than a 105 or even an Ultegra. It's not even all that heavy. If I didn't have so many bikes, I might have upgraded to a carbon fork. Be careful on the sizes, however. The stack is accurate. The reach is really too long for a 53 cm and is about the same as my 56 cm. You might need a shorter stem to compensate, Nevertheless, the best value and quick delivery out there. Get this bike!

### ⭐ Not so great
*by H***S on October 30, 2019*

Below average quality, beautiful but not a great bike purchase the bike on September 2019 ; one of my spoke pull off after ruding it for 500km all attempt to get Chris CRM at Tomasso to attend to this problem fell on deaf hears. I replace the tires to gator skin 700x32c road bike tires and trill began . It became a very fast bike and I love it
