As I was searching around for possible rims for my upcoming Brompton purchase, I stumbled upon a possibly new option. They are not listed on the main part of Velocity's website, but are listed in their web store. I would imagine that they would fall in between the Aerohead and Aeroheat rims in weight and width. The specifications on the webstore and on the main website conflict as far as the Aerohead's weight is concerned, but I think the main website is correct. It's only available for sale in 32 hole, but the store specs list 24, 28, 32, and 36 holes as possible options. I noticed quite a few other inaccuracies between the store and site also, as the Aeroheat is only listed as 32 hole on the website, but available as 24, 28, 32, and 36 holes on the webstore. The Aerohead rims are also listed in more sizes on the webstore; 20 and 24 in addition to the 28 listed on the website.
