|The short answer? No, your frame is not compatible with the new RockShox Deluxe and Super Deluxe shocks. The Bronson is designed to work with shocks that have an eye-to-eye measurement of 200mm and a stroke of 57mm. With metric sizing, the closest eye-to-eye measurements are 190 and 210mm, neither of which would work properly with your frame. |
That being said, it's worth a little more explanation to try and clean up the muddy waters around the whole 'metric' standard. I think it's the actual word 'metric' that's causing confusion more than anything. After all, the dimensions for any shock can easily be converted from imperial to metric - what's the big deal? Basically, SRAM decided to revise the current system to make shock sizing more uniform; instead of having a mishmash of eye-to-eye measurements and stroke lengths the progression between sizes will now be in even increments. For example, there are currently shocks with eye-to-eye measurements that measure 190, 197, 200, and 215mm; it doesn't take a math wiz to see that the gaps in those measurements aren't the same. Under the new metric sizing system, standard mount shocks will come in 190, 210, and 230mm eye-to-eye measurements. The simplification also means there won't be a need for as many mounting hardware options, making it that much more likely that a shop will have the part you need in stock.
There's also the fact that by fixing the sizing, RockShox (and the other companies that will be adopting the new system) will be able to deliver shocks that have a consistent feel no matter the length. The air spring curve remains the same across the line, which makes it easier for frame designers to achieve their desired suspension feel. You can read more about the other design features found in the new shocks in our First Look article. For riders who aren't planning on getting a new bike any time soon but need a new rear shock, even though what you end up with won't say 'Deluxe' on it, non-metric shock options should be available for at least the next four years. - Mike Kazimer
|Thanks to the many hub standards blessed upon us by the mountain bike industry, there's a sinking feeling that is becoming more common. That feeling when you have spent hours meticulously building your dream sled, wheels are prepped with discs, cassette and tires, and all that is left to do is pop the wheels in and ride off into the sunset; then you discover you're 7mm short (this actually happened to me recently with a front Boost fork). |
I couldn't find the answer to your question, Matthew, so I gave the guys at Hope a call: "It is a simple spacer change on our hubs. We use the same spacers to swap from 135 to 142 as we use to swap from 150 to 157. The part number is HUB242. It's sometimes a little confusing as we also call them an X12 conversion which was the original name for the standard when Syntace created it. There's a chart on the technical section of our website showing all the conversion part numbers." I hope that helps. - Paul Aston
