Anyone Remember when index shifting..(27 posts)

Anyone Remember when index shifting..Lone Gunman
Mar 12, 2002 9:35 AM
first came out and the shifters were downtube type with 7 speed cassettes? Was just the rear indexed and front friction? Looking into another project bike I own and am thinking of going back to the DT index shifters that were original type. This retro thing has got me bad!!
just the rear on my wife's bikecory

She still has a seven-speed indexed Bridgestone roadie, and only the rear clicks. The front (a double) is friction. I have a seven-speed Allez Sport w/triple that's pretty much a beater now, and I think that was indexed only in the rear, too. But I've had friction barcons on it for so long I can't remember for sure.
Indexing the front, especially on a double, never has made any sense to me. It's like indexing a light switch.

Actually, the rear was a freewheel not a cassette. I had a very good but mid-'80s frame built up for use on a windtrainer a few months back and the mechanic who did the work was very impressed with how sharply the original click shift Dura Ace shifted. They work beautifully.

I had a Guerciotti SLX with 7 speed index, it's just the rear. Also stick with Dura Ace with the index, the Campy stuff didn't work. My LBS put Dura Ace on my Campy bike, it worked great. Don't know if I could give up my STI's though...This is not trying to start a Campy vs Shimano debate, but the Shimano index just worked better....IMHO
Yeah, stick with Shimano if you plan toscottfree

index shift. They nailed it better than Campy or Suntour. You could get away with much more imprecision in adjustment before the indexing failed. "Range of usability," I think they called it. Suntour, especially, required some pretty nit-picky tweaking if you wanted it to index well.

I think Suntour's derailleurs and friction shifters (Power Ratchet) were superior though, and a real groovy retro approach would be to go pure friction.

Either way, you wouldn't index the FD.
agree .....good advice NmSpirito di Finocchio

Amen to thatLO McDuff

In the late '80s I opted for the New and Improved Campy Syncro II!!! (I assume that it was improved over Sycro I). It was a POS that never worked as hoped. Fortunately, you could pull out and turn a ring on the shifter base that enabled the shifter to work in friction mode.

If you are going retro, I'd second the Dura Ace.
Index shifting ... retro?pmf1

Maybe my age is showing here, but I remember when index shifting came out and all the old retro guys made fun of it claiming that "real" shifters aren't indexed. Took the art away from shifting.

Remember the Simplex dereailer?

anyone know where to get suntour "ultra" 6 freewheels wider than the 13-22 or 14-23 as at harris cyclery.

forgot to bid on a 13-26 that passed recently on ebay (i hate auctions).

Call Performance and get the scoop on those supposed Suntour freewheels they have in their new catalogue!

its a misprint and is actually the sachs freewheels to which they are referring to.

bummer.
I RIDE A 7-SPEED DA INDEX DOWNTUBE BIKEsurf

I RIDE A 7-SPEED DA INDEX DOWNTUBE BIKE

The thing works perfectly for me, very fast crisp shifting. I just cant get used to pulling the arm off the bars to shift. I guess I can say I'm retro instead of a newby who bought an old bike.

How about this, how much can I get if I part everything out. The frame is a Miyata carbon fiber (58cm). Cranks are Sugino with CF also on the big ring. Wheels are Campy 32 spoke. Everything else is DA.
Don't part that bike out!scottfree

My commuter bike is suntour 7 speed downtube index shifter set to work as friction shifters in order to use a Sachs-Malliard freewheel that is not spaced correctly to work with the suntour index spacing. I find the shifting quite smooth and easy to get used to. Front shifter was/is friction only, as is the norm for all 7 speed shifting systems, I believe. To experience true retro and really develop a feel for your ride, go friction. BTW, my weekend ride is Campy 8-speed DT index shifting. Makes a nice contrast.
Is it Suntour Accushift? Can you actuallyscottfree
Mar 12, 2002 11:25 AM
get the 'friction' mode to run pure friction, or does it 'soft click?' I have a beater with Accushift, and I'm damned if I can get the thing to eliminate clicks altogether. I understand there's a trick, involving removal of a ball bearing in the mechanism, but it's never been fully explained to me.
The original was ExageLone Gunman

The bike is a 1990 Schwinn Alu (Klein was in on this work) and it was upgraded to BE shifters for a while and now RSX 7 speed shifters. The original top end Alu for that frame set spec'd Ultegra everything and I have upgraded alot of the parts over the years to a mix of Shimano parts. I need a set of chainrings and the DT's and I could be Retro'd again. Always liked the ice blue paint on the '90 Schwinn 974 and may go with that as a color.

I agree on everyone's advice on the Shimano over Campy index shifters. I had several Shimano indexed 7 speed bikes and then bought a Tommasini and built it with Chorus. I ended up using the friction instead of the indexing.

I think if I were to build up a classic down tube shifted bike, I'd use friction. After learning to master it, you can shift just as quick and precise as indexed. Shifting with friction is also very quiet, which was an advantage when attacking without getting everyone's attention with a loud indexed shift.

Yep, I'd like to have both a modern STI bike as well as a nice old lugged steel with down tube shifters.
quiet?laffeaux
Mar 12, 2002 12:34 PM
The shifters might be quiet, but the "clunk" of the non-ramped rear cogs was very loud. I ride an '89 7-speed mtb with indexed thumb-shifters on my trainer, and the shifting is by no means quiet. Compared to today's smooth shifting bikes, it's pretty bone jarring and loud.
Friction: quiet. Indexed: CLUNK! -NMTig

6spd index had front indexed..dotkaye
Mar 12, 2002 11:28 AM
have a 6spd with dt indexed shifters, Shimano Exage, and the front shifter claims to be indexed. I've always had it set to friction, though - could never tell the difference, frankly.

Actually, Shimano introduced SIS shifting on WalMart quality bikes. They used these lower level bikes to develop the technology, and then they perfected it on higher level bicycles. Remember that?
Yeah, it was pitched to kids and recreational riders. 'Real'scottfree
Mar 12, 2002 11:37 AM
riders sneered because it required no skill. Suntour and Campy passed on developing the idea because they thought it was another one of those nutty Shimano things. (Although I believe Suntour had a very early pre-Shimano indexed deal called 'Mighty Click' that was briefly used on kids' bikes.)

Diamondback Centurion CRMO steel (1990). Came with the Biopace II rings. Everything works just fine. I still use it on the stationary trainer.

I moved up to the Trek 5200 last year. There was a few years where the old DB sat though.

Happy riding.

I still have my 1986 Raleigh 531 Comp road bike (Made in Nottingham) with 6sp Dura Ace. Indexed shifting, DA freewheel, brakes, everything except for the headset. It's Campy Record of the same vintage (still think it looks better than the DA headset of the time).

The bike is just hanging in my garage nowadays but it does bring back a lot of memories.

was a new 1980 Fuji Grand SE (453 Reynolds....must've weighed 25#) with friction shifting...I rode that until I upgraded to Dura-ace STI...what a difference !!!!!
