Hope Pro II 20mm Front Hub and Notubes ZTR 355 Review

Pro Reviews

Bottom Line:

The Hope Pro II 20mm front hub has been running like a champ since day one and I have not had any issues with it. With the ability to convert the hub to 15mm or 9mm with a simple and fairly cheap converter is an incredible option. This is a stellar hub and I couldn’t find anything to really quibble about, though on occasion the 9mm or 15mm converter can get a bit stuck and a vise or another tool is needed for extraction. The Stan’s Notubes ZTR 355 rim has performed flawlessly and the 20mm axle really helps stiffens up this lightweight rim, although it still has a hint of flex on nasty terrain . The combination of the Hope Pro II 20mm hub and the ZTR 355 rim is really a great wheel for most anyone but heavy riders and jumpers. The wheel was impeccably built by Notubes and they are a great candidate for a custom wheel build.

Strengths:

  • Hub – Easy conversion between 20mm or 15mm or 9mm axles
  • Hub – Multiple colors
  • Hub and rim – Light weight
  • Hub and rim – Price
  • Rim – Tubeless tire ready

Weaknesses:

  • Hub -The 9mm and 15mm conveters can get stuck and a vise is needed for extraction
  • Rim – Slight flex in the rim
  • Rim – Jumpers, hard downhill riders and Clydesdales need not apply

Value Rating: 5 Flamin’ Chili Peppers

Overall Rating: 4.5 Flamin’ Chili Peppers

    I have the WTB laserdisc light hubs (basically same as AC, right) and I was thinking about this problem this weekend…how much of a difference is there between the hub shells on these hubs (AC vs. Hope)? If you take apart your AC hub (remove the QR caps) don’t you basically have the same thing as the HOPE hub? If the bearing sizes are different, would it be possible to just replace with bearings that made the setup match? ( just have to match the inner diameter of the HOPE hubs) Just curious on how creative you could get here, but it seemed like it might be simple for WTB or AC to made those little conversion parts and make their hubs convertible too.

    Let me check my AC hub when I get home tonight. I am not sure what the new AC hubs look like, perhaps at the show in 2 weeks I will have further information.

    What’s with all the random quotes, they seem to almost relate to your review but not quite. Are you just another twisted bike rider? Good review by the way, but isn’t time really the test for a hub? I mean, can you tell from a couple of rides if this is the one you want to depend upon?

  • pastajet says:

    Yes I am warped. Are the quotes supposed to relate to the review or just my demented mind? I only have so much time to do a review unless it’s an extremely long term one. I have ridden the wheel for around 5 weeks now which is around 15 hard rides on abuse terrain so I have a pretty good idea of how they ride and their durability. In regards to long term longevity that I can only conjecture. It is going to be pretty rare to have many media reviews that are 6 months to a 1 year long. Check back on my blog and I will strive to keep an active long term section for all my review products. It is fun to do reviews but it is also a lot of work. You need to keep track of your testing and try and be as objective as possible and then you need to create an interesting review for the reader, which I always try my utmost to accomplish. Entertain!

    Nice pull. From “The Sure Thing”. A classic Cusack 80′s movie.
