Custom Racing Number Plate Mount Bracket Holder for Seatpost

It took a while to find a race plate holder that I thought would work with my Cervelo P2's seat post. This one looked like my best option. The bracket allows the trailing edge of the P2's seat post to meet with the deepest part of the bracket. It's not a perfect fit as the bracket can slightly wobble side to side (easy mod to fix that) but considering its made for aero seat posts in general and not Cervelo specific, it's a pretty good product.Why didn't I give this product 5 stars? The rubber rings are short for my post, so I might have to buy some longer ones if I can't find my spares.The description states the item shape is "V", so if your seat post is round, oval, or something that's kind of aero, but doesn't have a sharp angle trailing edge like the seat posts on Cervelo's P series bikes, or any other true aero manufacturer's seat post, then this item won't work with your bike.If yours looks like mine, then you should be good to go.I'll update once I get the proper length rubber rings, then again when I put this item to use after my TT in a few weeks.Update: I found a few long rubber rings, now the bracket is firmly in place. I'll update again after my next race.

I bought one of these about a year ago for an aero seat post. That one fit fine. I bought this one for a round seat post. Ahhhh....the holes for the bracket and the number plate don’t line up! It’s like a blind monkey with a drill put the holes in the number plate.

Great product and super easy to install

The bracket...The concept is ok and well made. The only flaw is the aluminum bracket, witch is too narrow for any seat post (mine is aero) and also it should be made of plastic instead of metal to avoid scratches
