I cannot tell you just how happy I am with the bike. Not only is it striking in its appearance but it rides like no other tri bike I have ever been on. The combination of speed and comfort is unsurpassed. I was on a fast descent the other day and I felt like the bike was in rails.

I have dreamed of riding a beam bike since I fell in love with the sport in the early 90’s. Talk about perfect timing for the Dimond release. I am happy to say that for this 6’7″ giant the Dimond is the most comfortable bike to pilot. Not to mention it is quite the eye catcher. I highly recommend this bike for any of my taller brethren.


I absolutely LOVE my Dimond bike. Super smooth and responsive. Just be prepared for all of the looks and questions you’ll get in transition before and after your race. I tortured myself about what bike I was going to buy and I can certainly say that I’m completely satisfied with my decision.
