Bike Racing Number Plate and Bike Racing Number Plate Mount, Race Number Plate and Cycling Number Holder

Matches the product description, fit a carbon aero seat post - snug and doesn't appear to move. The race plate is a bit smaller than I anticipated, but that is not the product description fault. 4 stars only b/c I haven't used it in an event yet. The mounting piece seems solid, and overall was easy to attach to carbon aero seat post design. Thanks!Still holding up, withstood multiple 70.3 ironmans and a 140.6 ironman. The only improvement that could be made is having multiple attachment bands, but that is beyond a reasonable expectation.Bumped from a 4 to 5 star review because this product deserves it. Thanks.

Overall a good product, does the job. But I did have to seek out different mounting hardware, the included o-rings did not fit my seatpost. I was in a bind and had to use small zip ties but I have found different o-rings. I heard of people using rubber bands but, use what works for you. I would but again if I needed

Item works great, I bought this to hold my race number on ironman 70.3 Costa Rica.Works great as I no longer have to put the race number sticker on my bike frame, therefore no more sticky residue to wash off the bike.

Product came broken, was unable to use. The black plastic piece that holds the plate came in the bag broken. The plate seems to be well built, but I was not able to mount it to the bike, unfortunately. Hoping to be reimbursed somehow, or sent a new frame piece.

I couldn't even finish installing it and it broke on me. It wouldn't even stay put on my seat post
