Each one is suited for different kinds of riding.

Climbing and descending were far superior, all you had to do was remember index fingers for easier gears, for both the front and rear derailleurs. I was sponsored downhill racer for years with with no Rapid-rise failure EVER!!! <br /><br />The ability for me to bomb down a super steep hill and know exactly what gear I would need and grab all of them or only one of them was the only way to go, I cant count the number of times it saved my bacon. Conversely on the climb I could be standing and hammering, and click a gear, and the chain was loaded against the next taller (lower numerically) cog with a spring, so it would only climb to that gear when there was a proper ramp and it was MUCH more predictable, and reliable. If you timed your shift when your pedals were at 3 o'clock, and 9 o'clock, the shift was so fast it was imperceptible, you didn't need to let up on the power, just time your shifting correctly. I kinda quit mountain biking from 2004 to about 2016, and now I am back at it, and so bummed to not be able to purchase rapid rise for my newer 10 and 11 speed derailleurs. I got into mountain biking very early on, 1984, and had over the bar shifters or Grip shift until Rapid Rise came out. Then I bought a high end bike and it came with Rapid rise, and I never knew any different, until I threw a leg over a friends bike, and man were each of us pissed, back and fourth trying to extol the virtues of each of our derailleurs, as the author says, "What works for you is the best." But I am sincerely bummed Rapid rise didn't remain available until today. <br /><br />If only Shimano had made a backwards shifter at the lever, (to compensate for the opposite operation at the derailleur) then all those that couldn't get used to Rapid Rise would DEFINITELY reaped the benefits of Rapid rise and see what I mean.<br /><br />At one point I had listed all the benefits, and there were a bunch, but I cant recall all the reasons why now, below are just a few.<br /><br />1. Index fingers easier gears. Much easier to teach new riders.<br />2. Chain climbs the cog ramps with spring pressure, not thumb pressure. <br />3. The spring does not have the capacity to pull the cable through its clamping mechanism or put undue stress on the the ferrules, or bend the chain, or the tall unsupported cogs.<br />4. No Ghost shifting on hard core G-outs.<br />5. Shifting to harder gears is instantaneous and much more predictable.<br />6. You can never grab a half a gear, or a gear an a half, or over shift, and ruin your chain. it just wasn't possible, it always grabs only the number of gears you click. Its WONDERFUL that way.<br />7. Shift from gear 9 (smallest cog) to gear 1 (biggest cog) while the pedals are stationary, and the first half of a pedal stroke your chain will climb to the expected gear. This is kind-of BS, as RR will actually climb a maximum of, between 4 and 5 gears, because the lever mechanism needs some spring pressure to let the index mechanism go (click) uphill (easier gears). BUT, on your super gnarly DH, where there was a nasty 1st gear climb at the bottom, I would grab 5 gears, do half a pedal rotation and grab another 4 and this was something that was impossible on non-rapid rise. Not impossible, BUT, I was concentrating on the gnarly course, and spent very minimal time thinking about shifting as I LOVED my Rapid Rise. <br /><br />Shimano, PLEASE BRING RAPID RISE BACK!!! Only this time introduce an opposite shifter so all the other people who hated it will see all the benefits I am talking about.

Stathis...My brain is on Rapid Rise and loves it! <br /><br />Stathis Bikos information (in post above) about the functionality of this kind of shifting device is just what I love about it. It zooms into the 'Low' range so that change-ups in the landscape from decline to incline can be pedaled strong right up to the nadir and then you can find your 'low' climber within milli-seconds.<br /><br />I buy them when I can and have a stash hedged against the current abandonment of this tech that will likely last until I take the long dirt nap. <br /><br />I have 5 bikes outfitted with them, two of them are my old recylces stashed in South America for programs and the rest adorn my townie bikes and my 29r. I have four more on the shelf, XTRs, and another back-up down in Santiago. One of those off the shelf will go on the Motobecane Fatbike here soon as I denature it to 9 speed from 10 speed just to be able to rig up a low normal XTR. <br />SO<br />Fast shifting<br />More Weather-Proof<br />Intuitive : Front and Rear Derailleurs work on same Principle.<br /><br />My Brain is on Rapid Rise because it works.

My Mid-Life crisis is being restrained to 9 speed derailleur for a while yet since RR is out of favor. Your article gives me hope of a resurgence.

If nothing else, I might be getting sore thumbs just because I'm older.<br /><br />I guess the main reason I never liked rapid-rise is that even when I was doing a lot of mountain riding, I was a road rider first and foremost. To my knowledge, no road shifting system made today is low-normal in the rear. I like to make as few adjustments as possible when I shift (pun intended) from one kind of bike to another.<br /><br />Happy New Year!Justine Valinottihttps://www.blogger.com/profile/10852069587181432102noreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-42421430847140583212015-12-29T10:21:24.707-08:002015-12-29T10:21:24.707-08:00another vote for rapid rise here, on very hilly or...another vote for rapid rise here, on very hilly or racing or racing very hilly courses the precision it gives me through the changes is excellent. This is opposed to sweeping through the gears hoping to hit the one you need for the gradient.

The mechanism itself was sill good; I just couldn't find a replacement spring and didn't know (at the time) how to replace it.<br /><br />I don't think I said anything about the durability of low-normal rear derailleurs. Having so little experience of riding them, I can't speak of their longevity. <br /><br />You may like such derailleurs--as the previous commenter does--because you ride under conditions in which I haven't ridden much, or at all. Perhaps if I'd been a more dedicated off-road rider--or pedaled a pedicab for a living--I might appreciate low-normal derailleurs more.

You generally can't judge the merits of any technology on the natural friction caused by the simple fact that people will tend to cling on technologies they are already familiar with.<br /><br />That said obviously newer is not always better. For example implementing dual control levers on MTBs was decisively misguided, as bikers tend to rest fingers on the brakes during technical sections and that would eventually move the lever just enough for the chain to jump cogs. That's not to say no biker flourished on the trails riding dual control levers. But that's besides the point.<br /><br />Low normal rear mechs actually addressed two inherent problems of the way rear mechs operate: <br /><br />1: bump shifting: trails are hard no the vertical Gs... Those have a tendency to mess with your mech as bumping your rear wheel will sometimes send your mech flying down against it's spring and shifting into a lower gear momentarily. I've had a couple of tumbles because of that running old LX top normals in my day racing cross country. Low normals are resistant to this because to travel down during a bump they have to work against the cable (witch is not possible) and therefore are virtually immune to bump shifts.<br /><br />2: cog ramps: Up-shifting simply pulls the chain out of the cog and drops in onto the smaller one. But down-shifting smashes the chain against the larger gear and expects the chain to grab onto an up-ramp and climb onto it. Low normals use the spring to do the smashing, witch provides even and controlled pressure on your cogs. This is far safer and far more efficient than you mashing the lever.<br /><br />Apart from those very important problems solved, there are other reasons low normal is the bomb:<br /><br />FAST upshifts: Coming out of the trail and mashing the release lever will get you through 9 cogs in a heartbeat! There is literally NO time needed to get thorough you entire cassette if you need to, and it happens in a controlled manner without the fear of pulling anything out of alignment, or smashing your mech against the low-stop (witch many a-time has pulled the rear mech out of tune on bikes with not many rides since last replacing shift cables).<br /><br />When up-shifting you use your thumb against pretty much nothing, so the feel is lighter.<br /><br />PRECISE up-shifts when you REALLY need them: Anyone saying he hasn't messed up an up-shift when climbing a steep uphill, out of breath gunning for the finish line is either lying, forgetful, or not a racer (ok I exaggerate for effect :P ). You will sometimes pull a little two hard and almost change two cogs instead of one and get that horrible clung of the chain falling back down a cog. That can put you off balance and cost you time. Low normal let's you leave the difficult job of being precise when you actually need it: climbing uphill. <br /><br />I understand it being difficult for many to get used to low normal (I curse and moan and kick when I get to use my freeride rig witch has an standard top normal mech! ) But once you actually get used to the low normal it's hard to go back.<br /><br />I never got the feeling flimsy part you mentioned. I have an OLD 2004 XT and apart from picking up an ever so slight slack on the hanger bolt pin after 11 years, 2000Km and a few medals it's still absolutely rock solid and precise. I obviously had to change the pulleys once but that's it.<br /><br />So the point is: anyone doesn't like low normal: I absolutely get you, it's not everyone's cup of tea. After all to each he's own and what works for you is the best.<br /><br /><br />But It's definitely NOT a useless fad, and it's definitely not inferior to top normal.Stathis Bikosnoreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-84451723189037287422014-10-17T16:45:41.038-07:002014-10-17T16:45:41.038-07:00as a pedicab (bike taxi) in a hilly city, I insist...as a pedicab (bike taxi) in a hilly city, I insist on low-normal/rapid rise rear derailleur.<br />it allows me to downshift under torque while pulling up to 1,000lbs uphill. on a more traditional rear derailleur, i would have to reduce my power input in order to downshift, destroying any momentum i could have kept with the rapid rise.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-12003123436803876152013-04-06T13:10:48.297-07:002013-04-06T13:10:48.297-07:00I used to ride with a high-normal front derailleur...I used to ride with a high-normal front derailleur, until it wore out and all I could get was a low-normal.
