Old bits of shirts as hole plugs with a spoke to push them in (does this work?) Yes- it works well... thicker rag material seems to work best- like an old towel.

We don't use a whole lot of DAQ on prototypes. We have stored files and can run them through a shock dyno. Generally I've used linear position vs time and some accelerometer based stuff. Sounds like a cool project!

Gotcha. Yeah- I think the Showa/KYB were advertising their chassis as the second air chamber- like if the main air spring were to fail- the air would still be trapped in the fork leg and still provide enough spring to help you get back home.

It sounds like you are on the right track. In school- I did an independent study in place of an elective and built a gear-box bike frame. You might be able to petition and do a study on the subject of your choice. I would say any suspension in the future ... more »

Vivid air and coil are both quasi- twin tube recirculating shocks. The benefits are there, however cost and overwhelming adjustments aren't always the best.

I think other manufacturers are doing them. I don't see it as a high end product. the weight is too significant in my opinion.

We usually will do a tuning camp or at a minimum send multiple tunes/samples to the larger companies, take feedback and adjust as necessary. Usually we can get them comfortable on one of our multiple stock tunes, but if not we have done customs in the ... more »

Not currently. Most people don't experience too much mid-stroke harshness with air-springs. If anything air-springs are a bit soft in the mid-stroke (vs coil with same bottom out force). I think it would add a great deal of complexity and expense to ... more »

Agree. Ramp should be controlled by frame linkage. But sometimes a frame or rider needs more ramp (or less) and adding tokens is cheap, easy and accomplishes similar end result (limiting harsh bottom outs) vs building a new linkage.

I don't know about any secret test tracks in Durango... HB might if you can find him.

Nice- I did not know that... I think a progressive fork spring might be easier to do since it's not having to interact with a frame linkage.

Thanks for all the questions- I'm gonna log off, but will try to answer more later tonight if needed.

we're already making (since 2013?) a semi-active shock for Lappiere: http://www.lapierre-bikes.co.uk/technologies/ei-shock-auto

Reply to Forum Hot Seat - Dave Camp, RockShox Design Engineer 11/19/2015 1:53 PM

Thanks! Oh man- I actually don't think this is too far off... With how powerful/easy phones have become to use I don't think it would be too hard to implement. We already custom make the Relay shock for Lappiere, so the hardware side of things is close. ... more »

No problem- I understand the frustration. Yes SRAM is seriously focused on improving quality right now. The road hydro recall really brought the quality issues onto focus and since then there has significant effort put into improving quality. Obviously ... more »

It's normal- known issue that is being fixed. Hopefully it doesn't bother you too much

My understanding of magnetic fluid shocks is that they take a significant amount of electrical power to operate. This isn't an issue on a car or motorized vehicle, but on a bike you'd have to carry large batteries to make it happen. Also- I have heard ... more »
