Derby rims are most well known for their width – they were some of the first really wide carbon rims on the market, and one of the first with a hookless bead, and even after several years they are still some of the widest available.
Derby rims come in a variety of wheel sizes and rim widths, and several layup options for each. The DH and AM rims use more carbon than the XC rims to increase strength. Here’s the available options:
- 26″ x 40mm = 32mm inner width, AM (440g) and DH (465g) options
- 27.5″ x 40mm = 32mm inner width, AM (465g) and DH (500g) options
- 29″ x 35mm = 29mm inner width, XC (460g), AM (485g), and DH (525g) options
- 29″ x 45mm = 39mm inner width, XC (520g) and AM (550g)
The 29″ x 45mm rim is a new offering, and with a massive 39mm inner width this is a light weight 29+ rim. It’s not quite as wide as the alloy WTB Scrapper rim, which is the original Plus size rim with a 45mm inner width, but it is much lighter – the Scrapper is 715g in the 29″ size.
The other updates are small tweaks across the board for all of the rims. They all now have angled spoke hole drillings, which fixes my biggest gripe against the old Derbys. They also now have a pair of 2mm vent/drain holes designed to allow water to escape from inside the rim. By giving moisture a way out, the inside of the rims should stay much dryer, which will reduce the change of corrosion on alloy nipples. It also means you won’t pick up some extra weight when riding across a creek.
Pricing has not changed, meaning Derby’s are still some of the most affordable carbon rims available. Build prices start around $1225 before shipping and/or sales tax. If you’re interested in having a set built just for you, fill out my questionnaire to get the process started!
