Further Information

  • The rear wheel can be supplied with the option of 9/10/11 speed compatible alloy or steel freehub body or SRAM XD drive compatible.
  • These rims are UST tubeless compatible, they are manufactured to be fully sealed without the need for rim tapes.
  • The wheels are supplied with Mavic UST tubeless valves, sealant can be ordered here
  • We prefer to build these rims with 16mm brass spoke nipples. These are included as standard and we don't offer any other spoke nipple options.
  • For all the wheel aficionados, we build all our wheels with the hub logo lined up with the rim valve hole. A small matter, but important to those with a wheel fetish.
  • The wheel weights quoted above are genuine, complete wheels measured in the shop.
  • For further information about our wheel builds please refer to our Wheel Building FAQs.

Build time

Before ordering these wheels, please understand that the wheels will generally be built to order from the component parts. Items shown instock will be instock in their component parts, ready to be laced up, tensioned and trued. In most cases we can't pluck these wheels off the shelf, pack them into boxes and dispatch them, if only life was that easy. We will do our utmost to make the turnaround time as quick as possible (usually 7-10 days), but if you are in doubt, please Contact us first.

Wheel Builder's Comments

Brand new for 2016, the Pro 4 is Hope's brand new hub set. We start taking we orders for these on January 1st, and all our new wheel orders from this date will be supplied with Pro 4 hubs. Specifications for the hubs and wheel weights will be supplied as we build our first pairs of wheels. Now available with BOOST specific hubs and a choice of 8 different rim decal options.

The EN821 is a solid rim built for heavy duty trail and enduro mountain bike use. These have been a popular wheel build over the last year and feedback has been very positive, it's a shame they don't offer a 650b option.
