The reason is obvious why these hubs are so good. The quality if the machining and assembly is top notch. The configuration options are better than most hubs twice the cost, you can literally configure these to most applications out there with axles and drive hubs. These hubs are also very simple, dont need a college degree to set up, and the simplicity is what makes them so reliable.

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.

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!
These are just all around nice hubs. They are quite loud, though I expect most people looking at them are looking for a loud hub. The engagement on them is middle of the road, at 44 points. That's around double what you get on a lot of cheap hubs, around half what you get on a king or i9, etc.The machining and anodizing is good quality, and everything turns nice and smoothly.
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).
After recently crashing the stock wheel on my bike I decided to have another, better set built. The Hope Pro4's get great reviews, and won't lighten my wallet as much as some other hubs. I chose to go with a 36 hole version laced to a set of Stans Arch Mk3 rims to give myself the strongest option available. While I haven't had a chance to ride them yet, I'll say that I am really excited about having them and can't wait to get them out there. For this reason though, I can only award them 4 stars since durability can only be measured over long term use. I am a bit disappointed that of all the colors available, green is not an option... And last but not least... I love the sound!
Bought this hub this month and it arrives in my house in the box but when I open the box I notice that the hub has 2 big scracthes made by a plummers pleirs. How can a Hope hub arrive in my house with this big scracthes? Where this act of complitely stupidity was made??? In Jenson or in Hope factory???Sending emails to Jenson and Hope with the pictures to see what is hapening... completely disapointed with Jenson and Hope until I have the right answer.Thank you very much for your attention.
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.
