I just had my wheel built with the new hope pro 4 hub. I ordered it in orange to match some other components on my bike. It looks and performs great, my only reason I didn't give it a 5 star review is because of the hubs sound. I own a pro 2 and the pro 4 isn't any louder than my other hub. I've seen several videos with pro 4 hubs and they were substantially louder than mine. One of my reasons for buying this hub was for the sound so I am a little disappointed. But overall still a good purchase.

Extremely happy with my new hub!!! Used with the new Stans Flow Mk3 29 inch and they are unbelievable!!! I am smashing PB's up and down hill, in the worst physical shape of my life!!!THese wheels and hubs just roll so well hardly wasting any energy but transferring a lot of power to the train, as well as having spectacular handling.Very impressed with the responsiveness and how quickly my pedal power is driven to the ground.Loving the buzz of the freewheel too.Red anodising looks like it will last a long time.Great job on the new hubs Hope and thanks for the great pricing and fast delivery Evans - even if my order was forgotten for a few days... ;)

If you're looking for a high quality reliable hub at an unbeatable price, look no further than the Hope Pro 4 Boost..Fast engagement, and reliable, there's no better way to describe the Hope 4 Boost. There's no need in investing in a hub twice as expensive only to have a slight increase in engagement. The quality of the build is high quality and comes in an assortment of colors that will add flair to your rig.With Boost Rear as an option, these will work perfectly with the newer boost specs.I consider this money well spent and will look to Hope for my next upgrade

Hope Pro 4 Hub:It's hard to be original reviewing a Hope hub but I'll give it my best. For starters I'll say that this isn't my first Hope Pro 4 hub. My other one is in perfect condition and has seen a ton of use. I own multiple bikes with various aftermarket hubs and Hope Pro 4s are probably the best budget hub you can buy. I love my Chris Kings and Onyx are my favorite but when you don't need that superior engagement (72t and infinite respectively) the 44T of Pro 4s is plenty. They are also the easiest to service and grease and it's also easy to get replacement parts if you need to: bearings, axles, pawls, etc. Almost every part can be serviced without tools. You can also order just the freehub so it's easy to convert from 10/11 Shimano to Sram XD. Bearings are ... MoreHope Pro 4 Hub:It's hard to be original reviewing a Hope hub but I'll give it my best.

You can also order just the freehub so it's easy to convert from 10/11 Shimano to Sram XD. Bearings are very smooth considering the price and they seem to last. I replaced one on an old Pro 2 but it had seen a few seasons of use and was abused.They're not the quiet hub by any means. It's not so loud that its obnoxious but it's more of a definitive click at low speed and a good buzz when you're flying. The various colors add a nice custom look and they have a very nice finish to them. They're also one of the lighter hubs on the market.So to sum it up here what's good:Nice finished productMultiple colors and configuationsDecent quality bearingsDescent engagement (44T)Easy service and part replacment.Light weightVery low priceThe kinda bad:Not the same quality of bearings as brands like Chris King and OnyxNot as high of an engagement as others like Project 321 and I9As you can see they don't have anyany real weakness. If you wanna keep some cash and have a hub loud enough that it will scare any hiker long before running them off a trail, these are the ones to go with.
I've used a lot of hubs in my day but the Hope Hubs have never failed me. Mostly because of the simplicity. Keeping it simple with easy to access bearings is key and with a hub as reliable as this it's all you'll ever need to do. The swanky anodized colors are a plus. I'll keep buying from them. The other nice thing is that they are in most spoke calculator tools which helps when ordering spokes.
Great value, excellent engagement, and I love the sound. Coming from an 18-tooth Shimano Deore hub, you can really tell the difference on technical climbs. The anodized orange finish looks good but is a bit lighter in color than I would have lighted. I was unsure about the noisy hub sound at first, but now I love it. To me, it's the sound of precision engineering. As an added bonus, it helps alert hikers on Front Range trails!
I have three of these now. I needed a reliable, strong hub for all-mountain riding that was affordable. These fit the bill. Hopefully they hold up; I am a big dude and ride very aggressively. Nothing but good results so far. My oldest one is only 4 months, but no issues and still running smooth with several hundred miles on it. 44 points of engagement isn't crazy fast, but I find that the feeling between engagement improvements decreases dramatically after you get under 10 degrees (36 points). As for boost spacing, they say a boost hub on a 29er should feel like a standard 142mm on a 27.5, stiffness-wise; I highly disagree. I have Stans Flows built up on this hub on a SC Nomad (142x12, 27.5") and a YT Jeffsy (148 boost, 29er). Both 32 holes. The wheel on the Nomad ... MoreI have three of these now.

I have Stans Flows built up on this hub on a SC Nomad (142x12, 27.5") and a YT Jeffsy (148 boost, 29er). Both 32 holes. The wheel on the Nomad feels rock-solid, even though the bike sees bigger jumps and gnarlier rocks. I can feel the wheel on the Jeffsy flexing around like crazy and the rim has had to be trued out twice in 4 months of riding. Going to carbon wheels with 36 spokes for the Jeffsy 29er, despite boost. (I weight 230lbs without gear, ride hard all-mountain).
Amazing build quality, and very easy to service. This is one of the best deals for a non boost rear hub, and I was easily able to modify it and double the engagement from 44 points to 88 points. It has a great sound as well. The only thing I wish it came with is the steel freehub body. It comes stock with the alloy one, and my NX cassette dug into it pretty quickly. Other than that, it is amazing.
I have Hope hubs on both of my bikes. The engagement is awesome! It's really noticeable on loose, technical climbs. I wasn't sure if I would like having loud hubs, but it really is sweet. I haven't needed to service my hubs yet, so I can't comment on that aspect. I suspect that with regular maintenance, these will last longer than me.
Got the steel cassette body version for use with a 12 speed NX cassette. Wanted something a little tougher for the individual cogs, time will tell. Spins great, built up well, always forget how well Hope hubs are made, engagement is solid, not the fastest not the slowest, and has a nice sound, and spins really well. It does not use lock nuts or collars, just precision machined, similar to DT Swiss in that respect. For those who might be interested the 32 hole, with steel body weighed 394 grams.
