Please can you help me. I have an Anthrotec trike that has what I think is a SRAM dual drive 8 by 3 hub. It can only get 2 of its 3 hub gears. I would be grateful for any advice you can give.Best wishes, Bert

Today, I broke the second axle of my SRAM i-MOTION 3. It lasted a full 2 weeks. This is somewhat better than the 4 days the first installment has lasted.
I have been using F&S Torpedo 3-speeds for over 30 years and never had anything like this. The roads have not changed in the past weeks, nor have I. There must be someting fundamentally wrong with this design.

Knut – thats very intriguing about the broken axles. Could you put up some photos of the broken parts? Something seems to be very wrong – thanks for the update though.

The hub made a round trip to the SRAM (former Fichtel&Sachs) facility in Schweinfurt, Germany. Came back with the comment, that a piece of the axle was manufacuterd out of spec, probably leaving it vulnerable to breaking. Repaired free of charge. They had not seen the first one. At least they did not admit.
I had contacted SRAM by email and got immediate response and a phone call, asking for the bike to be returned to them through the dealer. Shipping and all else was taken care of by them.
Bottom line. Customer care of SRAM is ok. They do have a manufacturing problem that most likely affects more than just the two hubs that I have seen. So watch out for T3 hubs with manufactue dates around early 2009.

I was just cleaning out my bike parts box and found an old F&S Torpedo 3-speed hub with coaster brake plus some tools and spares for such hubs. I don’t think I will ever use these things so whoever pays me the shipping shall have it. Total weight is less than 2kg, within Germany that comes down to EUR 3.90 (small parcel = Paeckchen), international is more (check DHL.de).
The hub is the real old one designed to be used with an oiler (mit Oelnippel). It reads “515″ on the body and accepts 36 spokes. A 19-tooth sprocket is attached.
It was between 1980 and 1990 when I put this hub into the box, and I had salvaged it from what was an older bike back then. It tested OK at that time.

Martin– with the old F&S– still have that stuff? I have a few old and trashed hubs, and could really use parts. If so, send me an e-mail– threespeednerd@gmail.com. Thanks.

Haven’t received any reply to my mails, putting it on EBAY now.

Does anyone know the size of bearing balls used in a Spectro T3? They seem to be an obscure metric size, in between 3/16″ and 1/4″.

Hi, if the ball is between 3/16″ and 1/4″ it is 7/32″. It is a less common size today, but decades ago it was used in campagnolo freewheel hubs, some sturmey archer hubs and in your case Spectro (which was developed from Sachs) hubs, among others. Some headsets use/used that size too. If your LBS doesn’t have any, they can easily order you a quantity.
Hope this helps, keep your Spectro rolling!

Thanks! I had to dig the old ones out from the depths of the bin, but it’s relatively easy to replace the balls without stripping the whole hub again.
