Is this hub compatable with czar ion bike?

Hi Dima - This hub is compatible with the Czar Ion forks, but you would also need to get a Quick Release Skewer to go with it. You will also need new spokes as the hub dimensions are different on the Pro 4 to the standard hub supplied on the bike. Thanks, Mark
what do you mean by: "we can supply any version / fitment of the hub at no extra charge" I'm planning to buy and put it in my Inspired Fourplay. And I think I need the 15mm axle adaptors. Is it for free or I need to buy it separately? Thanks

Hi Mark - By this, we mean we can supply the hub with your choice of end cap if you mention it in the Notes field for your order. For example, for your Fourplay you'd need to request one with 15mm Axle Adaptors. Thanks, Mark
Hello 2017 Inspired arcade pro trial tech Is it possible to use the 15 mm adapter attached to the front hub shaft as it is?

Hi Hiroyuki - The adaptors for the Trialtech hub won't work with the Hope hub, sorry. You would need to use the Hope 15mm Axle Adaptors (Product code: 11295). Thanks, Mark
Hello, fits the Hope Pro 4 front and rear hub to the Inspired Flow fork and frame? Thanks!

Hi Simon - They would fit fine, as long as you get a Quick Release for the front hub. You'll also need a sprocket and a cassette lockring for the rear hub. Thanks, Mark
Hi, So recently I found the spank spoon 28 24" (Red) rims on spank.com I was wondering. Would they be able to stand street trials? And would they pair with the front and rear pro 4 hub, hope float rotor and magura mt7? Many thanks, Morgan

Hi Morgan - The rims themselves should be quite strong, but the problem would be the width. As they are so narrow, unless you ran extremely high pressures you would find you had much more tyre roll than with a wider rim, and also a much greater chance of getting pinch flats. Your tyre profile would also be a little more rounded than it would be on a wider rim. In terms of compatibility, they should be fine with the other parts you're using. Thanks, Mark
Hello Tartybikes! Is there an adapter for the BOLT IN System? I just found it for the rear hub. Thanks Dominik
