    Absolutely love this item. Fit perfectly, Big and beefy for a great look, and FAST shipping for a custom product. Mine arrived in a week. Without this, I would be in danger of cracking my downtube and ruining a 1500 dollar frame if I crashed. Absolutely glad I purchased this.

    Order with confidence! Great product and it worked perfectly. Very fast shipping as well.

    I’m 6’3″ tall and I needed to move my bars up a little but, I didn’t want to add more spacers under my stem. I ordered a 15mm crown race spacer and it raised my bar height by almost 1/2″ (13mm). Just what I needed!

    Thank you MTB Tools!!!
