I set up a dummy bike to test fit all the derailleurs I have. The M9 is simply built for 46t and up to 52t cassettes. Heavy return spring and non adjustable "Stabilizer" aka clutch. Too big for me. My Rapid Rise LX looks like it can go 40t with a longer B screw mod. But can I get it to shift an...

I've got the Zee in hand, and it is compact. The cage is shorter than my XTR GS. Weights Saint M800 9s GS RR 370G. No clutch . Zee M640 SS DH 270g Metal clutch lever for hard use. XTR M960 9sGS RR 200g no clutch Let's throw the Linkglide M5130 in here too. 360g. and 13t idlers making the...

I've just ordered a Jtek Shiftmate 6 (UK bodging supplies from SJS Cycles). This converts cable travel between SRAM to Shimano 8-9 speed ratio. Most often used to run the wrong shifters. But by reversing the mismatch that means derailleurs too. I adds or subtract travel depending on which...

I tried the M9. It seems like they just built a longer derailleur hanger into the deraillaur itself. It was pretty far away from the small cogs. But it does go up to 52t. You might look at the ZEE. There are 2 versions. The DH has the SS cage for 28t cassette. The FReeride is GS for 36t. But at...

I went with gripshifters. As many gears either way as I need. No time to twiddle my thumbs in urban South Florida traffic ( statistically most unsafe place to ride in the US). The Saint and Hone Rapid Rise both require hard to find 10mm through axles. The Hone hubs can be found cheap due to the...

A few more thoughts on this. If you own more than one bike. You may want to do trigger shifters on the non RR bike, and gripshifters on the RR one. This way shift habits can stay the same for each bike. ASFIK there are no RR triggers out there. They tend to ration upshifts, which with RR means...

The 68x131.5 square taper BB converted to 73mm (using a Shimano ES71 LH cup) lines up perfectly with the SJS/Thorn cranks, and ENO. So no more 134mm Cotterless Axle nonsense. I have another trick up my sleeve ( which may or may not work out). It's a very retro SRAM 9.0 Half Pipe 8 speed...

Plan B on this mod. I got all the parts from one Ebay vendor for this 2nd version. Much more modern than the Thorn/ SJS Cotterless Axle setup. With a sealed cartridge square taper BSA 68x131.5 bottom bracket it made a 60mm chain line, with 10mm between the Freewheeland the RH bearing Cup. I...

It turns out that the SJS/Thorn tandem BB axle is an unusual 134mm width. It fits with the ENO on a 73mm BB shell with 1mm to spare and a normal chainline for a 46t cog. If you need wider that might be tough with those parts. I do have the Ebay square taper and ISIS cranks for the ENO. I'll have...

The RR can preselect a downshift when stopped. There's one in the vid. But the FFW is usually already in gear.,and now my 2 bikes shift reversed. The BBSHD doesn't have torque sensing. If you're in 1000W+ setting and preselect a gear it can get messy when you start up again. I don't like to...

I did get one video posted of the Ebike showing this. The center stand and motor made it easier to film than the XC bike. I was waving the phone around with my left hand and working the throttle and shifter with the right. The pedals don't move during the whole video. @.40 there is a Rapid Rise...

My bike came with the old triggers. but I went to gripshifts and stayed there. I took some photos and video. But they're stuck in my camera. I'll have to make some more with my phone. It's kind of funny. I did the FFW on the Ebike, and then did the XC so they would shift alike. I tried to remove...

I agree that RR is pretty much necessary for urban riding. I see lot's of people hate gripshifters. But they never seem to give an actual reason why. I'm down to one gripshifter on both my bikes. Very easy to access any gear any time. I don't have time to twiddle my thumbs in traffic looking for...

This is the one I use that clearly says Rapid Rise. The numbers are correct, but it does turn backwards to others. The detents and spring loading are in the right direction for low normal derailleurs. There are a few of these left in the UK. Almost non existent elsewhere. 7s is fairly common...

I make a point of running RR Revoshifter with RR deraileur. The SRAM Attack stuff is sprung backwards which was OK until it rained and the spring loads ganged up on me. So I now use the Rare Shimano x8 RR Revo stuff. It was OK when all my bikes shifted backwards. So with the XTR pods it would...

I have to agree. My Ebike is 1x8 Rapid Rise with a correct RR Revoshifter. My 1x11 converted XC bike has a front freewheel mod so I can shift any time like RR, but they're both reversed from each other now. When the XC bike was 3x8 it was RR also. My wifes Nexus 8 IGH has the reverse pattern...

The spring resists cable tension. High normal has a spring also. It just works the oposite way. Nothing locked about it. I have 20 year old Rapid Rise derailers that work just fine (they're all 20yo by now). MTB guts didn't like it because Hi Normal could force a downshift when pedaling uphill...

This was nice to have on a 3x bike, but the front derailleur is Low Normal, and you could also dump gears there. On 1x bikes it's the only way. FFS or RR. I think they should be coming back with the 1x wide range cassettes we have now. I suppose that's not so Retro is it? The concepts are.

These are both obsolete Shimano technologies. I've used them both (separately and together). There are some similarities, and a couple differences. I'm still using them on current bikes. A 2004 MTB Ebike conversion, and a 2004 XC softtail converted to 1x11. WTH is it? Front Freewheel System...

Well I've come up with another little twist in this rather convoluted project. I began to suspect that the White ENO Ebike freewheel could accept the inner workings of their Trials freewheel. This adds 3 more pawls for 72 clicks per revolution (up from 36) for a 5* engagement angle. This seems...
