Hope Pro 4 Rear hub and Boost 148

For 2016, Hope has expanded on that trait with the new Pro 4, including a slightly longer freehub body dimension that’s now all available with Sram XD or 11S Shimano. It's supplied with freehubs to suit 10/11spd Shimano or Sram XD cassette.

Starting with their well-sealed hubs, they have added Boost 148 rear and 110 front options to the mix. It's a good improvement as they are following the trend and making progress.

The new Pro 4 increased flange diameter to make stiffer wheels and added an 11-speed compatible Shimano freehub.

"Hope says the new Pro 4 hubs are stronger yet, even more, versatile than before. There are several improvements we’ve introduced on the Pro 4 hubs. They now use a 44 tooth ratchet mechanism which gives a 10% quicker engagement over the Pro 2 EVO."

Despite Hope has made a bigger dimension, Hope sales and marketing manager Alan Weatherill says there’s no increase in weight for comparable sizes.

It's also a very important point for the concern of increasing the extra weights on the bikes.

The hub flanges move outboard 3mm compared to standard Pro 4 rear hub to increase complete wheel stiffness.

**Note** Hope Pro 4 Hubs are available after Jan 2016.

**Note**148mm hub uses a different wider hub shell and axle compared to standard 135mm Pro 4 rear hub

**Note**Supplied with freehubs to suit 10/11spd Shimano or Sram XD cassette
