Calvin / Park Tool - Rapid Rise derailleurs - new video

[J J]

The great Calvin at Park Tool did a video on Rapid Rise. Definitely worth five minutes of your time if you have any love for or interest in these fantastic derailleurs. 

His conclusion is interesting and ironic — as are his omissions. I won’t spoil anything here, but check it out: https://www.youtube.com/watch?v=v0Frzlzs7w8

That was well worth it.Calvin is a funny and smart dude. Helpful and entertaining 5 minutes.

Thanks for the link, was an entertaining 5 minutes. Grant commented on the video, including a potential timeline for the Riv RR derailer (6-10 months!).

Good vid, Calvin. I've been obsessed--maybe to a fault, maybe not--with RR derailers since 2005 or so, about that last year Shimano made them. I don't use them exclusively, because I have some perfectly working other derailers (big fan of the Shimano Altus M310 here...and Acera, etc). I may be less than 100 percent accurate with the timeline, but it's really close: Shimano made these from about 1999 to 2005. Disraeli gears (good site) may disagree, and I'd go with what he says. Shimano intro'd these to mtn bikes, not road, figuring mtb riders would be more receptive. But (as I recall) they intro'd it at the top levels--XTR, XT, LX, DEORE--and they couldn't get racers to use it, for fear of shifting the wrong way on a climb or something. And big mfrs were, for the most part, chicken to risk it. Shimano made the "mistake" of offering it as the freaky option to its normal derailers, and of course product mgrs opted for the normal ones. The Shimano came out with a line of RR ders for hybrid bikes for rich old guys, and that had no trickle-down effect, and probably even hurt them. But some of those derailers are magnificent in function (of course, it's Shimano) and value and looks. A few were super freak looking. My biz has bought all we could of them--maybe 200--and sold them, but (as somebody mentions below), we're working on "our own" version. Shimano won't remake it. I've asked, but who am I, and all Shimano cares about is the gigantic cmpanies spec'ing it, and they won't. So for 7 years now we've been plugging away, contacting makers, working with others nobody has ever heard of, and recently we've made a connection with a fairly famous maker. It's too early to say where it'll go, but by mid Nov we'll have drawings, and if all goes well, we'll have production in 6 months. In my experience, 6 months means 10 months, but whatever. There are lots of good normal derailers out there now. Another PLUS of RR: If you ghost shift, you shift to the easier gear. And both shifters move in the same direction for the same effect. Anyway--I am saying all this stuff because it seems relevant to this topic, not to promote my biz or to get. people jazzed on RR derailers. I am preemptively trying to fend off criticism here. Seriously, all we're doing it trying to resurrect a smart option from the past; not trying to kill off other derailers, not saying you're dumb if you don't like RR derailers. Just adding to the menu.

I think Jim has the largest collection of rapid risers among the forum so quite appropriate that he shared the link! Thanks for posting, always fun to watch Calvin's videos. This guy gave me the confidence to start working on my bikes. 

[Josh C]

Oh yeah, Calvin and I have spent some time together in the garage, that's for sure. Thanks for sharing.

+1 👍 RR

RR all in here since I don't-remember-when. 

Seems logical to have extra umph to power the derailer up the hill—literally and figuratively. One of my favorite ebay sellers kept listing so I continued collecting. Someone sat on an abundance of NOS so I helped relieve him of his burden.

The only issue / caution worth noting is that if you're moving back and forth low / high you'll have to be better than I was remembering to either pull or push. Especially when the road goes up quickly. 

Other than that, I don't understand the argument for high-normal.
