Hope Pro 4 6 bolt disc hubs built into DT Swiss GR 531 DB Rims

Customer Notice 01.09.21. Please read before ordering. 

Hope are still producing Pro 4 hubs but there is a significant backlog. Currently hubs are taking approximately 7 weeks to come through from Hope. This will have a knock on effect on our wheels. It is likely that custom wheel orders will now be 7-8 weeks for delivery. Please only order if you are happy to wait for your wheels. We cannot give refunds for cancelled orders as they are all custom. For those that do order, we appreciate your business and will get your wheels to you as promptly as possible. You will get your wheels but you'll have to wait in line for delivery. Thanks for your patience. 

Hope's Pro 4 6 bolt disc hubs handbuilt into DT Swiss GR531 DB endurance gravel disc brake rims. We have paired the Pro 4 hub with the GR 531 DB, DT's newest tubeless compatible endurance gravel rim. With a 24mm internal width and 25mm depth the GR 531 is available in both 650b and 700c/29er sizes making it ideal for gravel bikes.

In our opinion, these wheels stack up against anything else out there in the £500 price bracket. The reliability of the Hope Pro 4 hubs paired with a hand built wheel makes these hard to beat, even compared to Hunt and Mavic wheels. 

All our DT Swiss rim equipped wheels now have the option of silver alloy Squorx Prolock spoke nipples or Sapim Double Square Secure Lock Brass in Silver or Black. All these options are compatible with DT PHR washers. The use of these nipples allows us to use a slightly longer spoke for added strength and to build the wheels from the outside, reducing tooling marks on the spoke nipple. 

Some electric bikes now come with 110x12 and 15mm thru axle front and 148x12mm thru axle rear specific frames. We can now supply these gravel wheels with BOOST specific Pro 4 hubs.

32 hole wheels are available on request, please contact us for a quote and delivery time.

Ask a Question
  • Hi, Can you tell me if you build with straight pull centre-lock Pro4 hubs? Thanks, Mike


    Thanks for the message. Hope no longer make straight pull Pro 4 hubs and they don't make a CL Pro 4 either. We could however build those wheels with Hope RS4 straight pull centrelock hubs.

    Please email me at info@moonglu.com if you would like to discuss this further. 

    Kind Regards
    For Moonglu
