WHEN ARE SHIMANO GOING TO DO SOME NEW RAPID RISE REAR MECHS !
So far as I know there’s no more than 5 people on Earth who actually ever wanted “Rapid Rise” shifting, strictly speaking these backwards shifting oddballs should be shouted down, it was a technical/marketing dead end, get over it…
Don’t think a petition is really warranted.
That said I really want to try a RR/Gripshift combo out, just to see what such a back to front twist shifting setup would be like… Then I’d probably take it all apart and go back to proper shifting like what normal people have…Posted 4 years agohonourablegeorgeMember
I had one RR mech – it sort of made sense – was easy to grab a lower gear when you needed one suddenly, and you’re always pedalling strongly and probably on the flat/downhill when you need a higher gear, so the “harder” shift was smoothed a bit. I guess that was the theory, I didn’t go searching for another when it was time to replace, though.Posted 4 years agolovewookieMember
rapid rise and gripshift user here.
Thing with RR mechs is that they just don’t wear as quickly as the high normal mechs. (IME obv.)
I recently changed my M951 as the cage bolt wore out and became wobbly. The rest of the mech is in my spares box. Changed it for a M960, cheap off ebay.
so, a 15 year old mech dies, replaced by a 8 year old mech. still life in the old stuff. 🙂Posted 4 years agothisisnotaspoonMember
I liked RR, it just seemed to work better in the real world where shifting is rarely perfect and you don’t remember to ease it accross gentlty.
Probably wouldnt work with a clutch though as that already slows the downshifts. Or it would need either;
a) much stronger spring
b) a cluch that sensed the gear change, eased off the chain tension, then locked again when the next gear engaged. Would either mean 2 lots of indexing, or rolhof style indexing in the mech.
I give it one more revision before XT becomes a pinion style gearbox, with XTR remaining as chains/cassette/mechs for max efficiency on race bikes and <SLX the cheep dereilieur option. A bit like Ultegra getting hydraulic Di2 rather than Dura Ace.Posted 4 years agothisisnotaspoonMember
can’t see it myself, shimano already do a seperate hubgear range.
Precicely, so how long before they stick it up front in a pinion style box?
not sure what you mean there
I meant, typicaly the second tier groupset usualy gets the utilitarian upgrades first, like the original XT disk brakes. Whereas XTR/DA get the lightweight or race orientated upgrades first.
The Hydraulic Di2 is a non-series part, neither Dura Ace or Ultegra.
You seem more pedantic than the entire bike industry which seems to have called it ultegra (google: di2 hydraulic, every result on the first page calls it ultegra, or ultegra level), even shimano gave it a 78x part number, and its release shortly after the 78xx groupset.Posted 4 years ago

Shimano decided not to release this under the Ultegra name as the lever was more bulky than standard Di2 or even mechanical shifters. Lars VDH was seen using prototype (all machined aluminium) Di2 levers at a race a week or so ago, with a profile bearing greater similarity to the regular Di2 levers. I imagine these will become part of a named group.Posted 4 years ago

ah right I was not aware that DA didn’t have a hydro Di2 shifter. Makes sense now.
Still reckon we got a bit to go before pinion, mind you, how often are the groups updated? 4years? Was XT last year? So 6 or 7 years time for your theory, hmm…
Was about to ask would shimano really introduce di2 (which I reckon next XT will have) and then dump it for the next iteration? But then I remembered, this is the bike industry, of course they would.Posted 4 years agochestrockwellMember
I really liked the RR set up I had a few years back. Only changed because I bought a new bike without it. It was the only brand new XTR set up I’ve had though so I was never quite sure if it was the RR part that was ace or the XTRness. Changing up easily under load = sense to me.
Out of interest, do those who say it’s sh*t have any reason apart from ‘it shifts the wrong way’? Also, have they all used it for a decent period of time?Posted 4 years ago
