Rapid rise -- stick or shift?

[Retrorockit]

I've ordered a ZTTO lightweight 11-46t 11 speed cassette. Hard use and long wear are not part of the plan for this bike ( I have an Ebike for that).
$100.

I'd be tempted to change my whole drivetrain to rapidrise. Rivendell is working on the development of a new rapidrise rear mech so Grant P obviously likes it. I haven't read the whole thread, but if you're selling it I'm interested.

This is kind of a test for 1x Ebike conversions of old 3x MTBs.
The Rapid Rise derailleurs are not hard to find on Ebay. But reverse pattern trigger shifters don't exist AFIK. Only Shimano made reverse pull twist shifters for it. The 7 speed ones are fairly common. 8 speed are rare, and 9 speed never existed in my experience.
Start with this. Note the "0" suffix. That's typical of RR parts. Derailleurs should end in 0 also.

That's a good price and fair shipping cost. The matching front shifters are all the same 3x part. People want a lot for the XTR Rapid Rise stuff, and a lot of it is beat up from DH racing. But RR came in just about every other contemporary series. Due to lack of demand there are some NOS deals out there in other series like Tourney and LX. I think there is 105 stuff for road bikes too.

Rivendell has a page on Rapid Rise.

What's RapidRise?

RapidRise derailers for open-minded newbies When you have lever-shifters (downtube, bar-end, thumbies), you move the left one forward to get the low front gear, and you move the right one back, the opposite, to get the low gear. You’ve gotten used to it, because that’s what people do. A...

I've got another trick up my sleeve for this. Front derailers are all Low Normal. So front shifters are all "Rapid Rise". I have been agonizing for a long time about no 9 speed and up Rapid Rise shifters. I just ordered a couple of front Shimano Revoshifters with friction instead of SIS. They're from the triple chain ring era so should pull plenty of cable, and work with any number of gears. I have Rapid Rise derailers that can go to 11-40t w/o a hanger mod, maybe much more with an extended hanger. So may be I can break the 8 speed barrier with some retrotech. 2x11-40t should make a nice setup.
Moron this from Rivendell.

Shifting

FIRST, some things you should know about friction shifting, even if you don't know what friction shifting is. This will tell you that, too. Friction shifting is shifting without indexing. In indexed shifting, there are notches in the shift lever that regulate the movement, and when everything is...

I got the ZTTO cassette. 11s 11-46t lightweight version. I had read the reviews. Issues with chain coming off the larges cogt back pedaling, and chain not laying down on the largest cog. The problem is they didn't make a cut on the back of the cog to define the depth and width of the tooth. There is a shoulder there that's even with the bottom of the roller cutouts. The chain plates can't sit all the way down on the tooth. Looking on the bright side I guess it's about to get a little bit lighter.

I didn't update this thread because I started putting the material in a Front Freewheel Mod thread.

Rapid Rise vs. Front Freewheel (or both?)

I ended up with a 1x11 42t to11-42t Prestacycle HG11 lightweight cassette, and SLX deraillleur with SRAM gripshifter. (My 2004 Mavic Crossrides have that cassette spline already).
The ZTTO cassette was crap.
Some Rene HERSE 26x2.3 Extralight slicks finished it off. The White ENO custom FFW setup won out over Rapid Rise on the pedal bike. But it's still in play on the urban Ebike which has FFW mod also.
FFW= Shift with or without pedaling, real time shifts up or down, multiple gears with a gripshifter. Can't shift when stopped.
Rapid Rise= Can preselect downshifts w/o pedaling (pedal it into gear just before you stop). Can down shift when stopped if needed. Goes into gear when you take off gently.
FFW+RR= Any gear any time ( Like an IGH) Downshift when stopped, still need to take off gently.
RR up to 8 speed is affordable and easy to do. FFW on the converted mid drive Ebike is already there. Just a zip tie hack to activate it ( plus chain management/ false chainline upgrade).
The ENO FFW mod is a hardcore and pricey project. The ENO Ebike freewheel seems to be NLA now. But it was a bolt on project. It can still be done with the budget freewheel that comes with the tandem stoker freewheel crank from SJS Cycles. Creating a false SS chainline for a derailleur is not too hard but adds to the cost to do it properly. SJS recommends an IGH for these cranks.
The Intend Magick Cranks custom FFW setup is much more expensive than the ENO mod.....
