Sachs Spectro 3 x 7 spare parts question

Hi there,
Im new here.

I need a spare parts for sachs Spectro 3 x 7(1999). I checked Sram 2010 technical manual and it seems different diagram between Sram dual drive (till/as of Mar 2008) and Sachs spectro 3 x 7.

I asked some bicycle shop and their answer they don't know which parts to convertible.
So. please advice which SRAM spare parts are convertible to my Sachs Spectro 3 x 7? Some of T3 parts is similar?

I need those parts.
https://www.karstilo.net/hpv/technik/sachs_sram/3gang/3mal7/3x7_1.gif

No.6 Bearing with retainer

No.11 Pawl Spring
No.12"Pawl
No.17 Pawl spring
No.18 Pawl (note:it seems different width with 12. wider width than 12)

No.20:compression spring
No.21 compression spring retainer? (name unknown)
No.22 compression spring
No.23 bearing with retainer
No.25 bearing with retainer

There are a Sram manual for T3 2009.There are a parts looks like same parth with Spectro 3x9. (PDF P98). is there a same parts or convertible parts with Sachs Spectro 3x9(1999)?. (note:my 3x9 is different diagram with SRAM dual drive till/as of Mar 2008)

For example,
Pawl and the spring parts, NO.11/12/17/18 of Spectro 3x7 parts looks like same with T3 spare parts on Sram manual 2010
65 0512 115 200 / 11/ Pawl Spring 32 x 0,8mm T3
65 0536 104 100 / 12/ Pawl T3(2pcs/1set)
65 0512 115 200 / 16 / Pawl Spring 32 x 0,8mm T3
65 0536 113 000/ 17 / Pawl T3 (2pcs/1set)

Two compression spring No.20/22 of Spectro 3x7 parts also looks like same with T3 spare parts.
65 0525 104 100 / 19 / Compression springs T3
65 0576 104 200 / 6/ Bearing Retainer i3, T3, Sparc, P5

There are three bearing with retainer,
No.23 bearing with retainer(wide and short) No.25 bearing with retainer(narrow and long) for Spectro 3x7 looks like same with T3 parts. There also have a dual drive spare parts.

65 0576 104 200 / 6/ b Bearing Retainer i3, T3, Sparc, P5
65 0376 104 000 / 14 / Bearing Retainer Dual Drive
00 0391 012 000 / 16 / Set, Cartridge bearing, ball Retainer, Dust Cap for Driver Dual Drive, Qty 1

Nice hub, lousy company to deal with

I too own an older Greenspeed GTO (2001) with a lot of miles on it and had to repair the SACHS Spectro 7 hub a few years ago. When SACHS became SRAM they redesigned the hub and made the SRAM dualdrive. The company support for the Spectro 7 is pretty "iffy" so parts are very hard to find. I opted to have a new rear wheel built with the new dualdrive by the US importer of Greenspeed.

My own experience is that SRAM is notoriously difficult to get parts from. I had the owner of a large bike shop that I formerly worked in obtain parts for the SRAM hub in an old BikeE AT. It took him nearly a year to get the parts. That's why when my Spectro 7 broke I decided to get a new wheel. It is so bad with SRAM that when I found a used hub the same model as the BikeE hub for sale for just $25 I bought it and switched out the guts for the hub. I also have a spare dual-drive hub so that if the current one on my GTO fails I can switch out the internal parts without buying an entire new wheel. You might just look to see if you can find anyone with a Spectro 7 hub for sale and do the switching.

There is one company that rebuilds Spectro 7 hubs here in the United States but they will not sell you parts for a do it yourself repair. https://www.rideyourbike.com/sramIGH.shtml It probably would be rather costly to ship the wheel from Japan to them for rebuilding.

I would get in touch with the Bike Friday folks. They use the Sachs/SRAM 3x7 hubs on their 20" wheel bikes, and they have enthusiastic supporters all over the world.

given Sram absorbed Sachs , the 3 by 7 came out before the take-over , I believe..

Torpedo 3 speed parts may work .. maybe you can cannibalize one of those, ..

Hi there
Thank you for all who replies this post and PM me . I cannot sent peronal message because of system?

Anyway, I ordered T5 spare parts from U.K and I repaired the Sachs spectro 3 x 7 parts and works well and enjoyed BikeE riding in Tokyo again!. I checked parts number on the spare parts list of SRAM 2000 Spectro 3 x 7 parts and Sram spare parts list 2010 T3 parts. There are many same spare parts number. Only the "Spring cap" is not in those parts list. I tried the Spring set of P5. now It works well.

Timely thread for me, new owner of a 10 year old(?) USS Linear with the Sachs 3x7 hub. Well, 2x7 seemingly on mine. Enough for now. Will bookmark this thread. Thanks.
