I won’t go too deep with technical stuff and specs, which have already been mentioned in other reviews, here are my experiences with these bars so far.
The bar dampen vibrations well, the bar feels great, it was a huge improvement from 720 Bontrager race lite bar and stem.
Enough flex but not too flexible:
Some flex can be felt if you get some weight on the bar, for example with some front wheel trails moves, but nothing too crazy, but on the trial when shredding hard, there is no awkward feeling, these handlebars feel great, the defenitly dampend vibrations, but they won’t eliminate vibrations completely, that’s impossible, with narrow studded tyres, rough winter conditions can cause a lot of vibrations which will be felt even with silicone grips, I have not tried wider studded tyres yet, But I am quite sure it would improve degrease vibrations, but for summer riding, these bars have been greatm they dampened vibrations well, combined with silicone grips, they were a good combo, but harder you ride mroe dampenign you woudl want, So that’s why I have ordered Rev grips.
Survived several crashes:
The handlebars survived several crashes, I have jumped off these two skatepark ramps, and landed on the handlebar, no damage was done, I rode hard for several months later and no cracks.
I have also crashed while climbing a bike path, due to my joint slippage issues I accidentally did a brutal turn to the left and lost control of the bike, and the bike slammed hard down on the asphalt, there was no damage to the bars, but I bruised my shoulder.
I have noticed some white spots on the end of the bar, it’s probably just clear coat damage, it only happened on one of the two bars I got.
I have been riding through summer & winter, and the bars performed well, some say to avoid carbon in the cold, I have been riding in at least down to -10C, without any issues so far.
These bars are a great choice if you like colour matching bars for a custom build or improve the look of your current bike, but the white/silver look will fit any bike.
I have put it through harsh riding in all different weather and temperatures.
ca 75kg with all gear on.
Aa the temperature decreases seals shrink, wheels go out of true faster, but this will happen on any wheelset.
So far I have been riding down to -11 Celsius.
I have been riding below freezing temperatures, few weeks, I noticed the sound coming from the rear hub was dampened, and sounded like there was water inside, because there was water inside, the plastic seal shrinks when its so cold, which allows water/melting show to come inside, which happen on a -6 Celsius ride. But it’s not possible to make a tighter fitting seal, so I recommend to put grease between the seal and the hub freehub body, which will give more protection after I have applied grease to the seal, I have not had any more issues with water in the freehub. but don’t make a mess, clean up the access to avoid attracting dirt.
I also put grease in the rim holes and on the spoke nipples, provides prevent corrosion.
After a long time of riding the front hub did not need service.
After 1 meter drop with too low tyre pressure: we all make mistakes
Good thing is that I learn from my mistakes and never do them again.
one of the rear wheels got a small dent, I ridden with studded Suomi WXC 300 tyres, 30 psi was too low in turns because of squirming, but I later added 10 psi.
If can, of course, bends it back.
provides a true wheel for longer than 28 like Bontrager duster.
Hope made a noticeably stiffer wheelset than Bontrager duster 29er when going fast in berms or landing jumps, or in general hard riding, it really makes a huge difference
High-quality brass spoke nipples, accurate size, so easy to work with, unlike the nipples on Bontrager Duster wheelset. There is no twisting or bending or crushing or cracking of the nipples when truing the wheel.
It has an almost idiot proof design, it’s very easy to take apart, I love the freehub system, there is no too required to take off the freehub.
10 & 11 speed compatible, hope provides a spacer for 10 to 11 speed cassettes, and the freehub body is wider than a 10 speed freehub boy, so the cassette is further to the right/closer to the frame, which results in a better chain line, for 11 speed,and no chain drop when backpedalling, unless you backpedal using your hands at unrealistic speed/rpm, I have been doing backward 180’s without any issues.
The wheels stayed true for a long time & no damage to the rim was done, after 3 weeks of hard trail riding, and some hard street riding, but after those 3 months it needed a quick retention, but it was a piece of cake.
the freehub is not too loud.
end caps for skewer or 12mm & 15mm axles
very easy to do maintenance/service no springs jumping out or tools needed(not counting the cassette tool)
I managed to get a small dent in 2 spoke nipples, but it did not affect the threads, might have been a big stone that hit them, the dent was only one side so I could get the spoke tool on.
not the highest engagement, there are other options on the market that provide better engagement, Industry Nine, Chris King, and the king of engagement Onyx due to the clutch, it provides infinite engagement, but they all cost a lot more. the engagement is ok, it does not feel awkward like the cheaper Shimano hubs do.
A closer look at the Pro 4 hub:
Springs eventually wear out:
this is to be expected, it’s normal, springs eventually fail.
Hope offers a wheelset that can take major abuse, for a cost-effective price.
But I want to try other hubs like Onyx with more engagement for my next bike.
I can recommend this wheelset if you want a wheelset that is easy to work on, for a decent price.
