GTO

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.

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.
