    TSR 2 --> TSR 5 mod

    I recently moved from NYC to SF and soon came to the (literally) painful realization that my TSR 2's gear range was inadequate for the hilly terrain. What's more, the S2C hub had become increasingly unreliable. After some research I decided to replace it with a SRAM P5. It's the only gear hub that offers more than 3 gears, includes a coaster brake, and still fits into a 120mm dropout.

    Since there is no cable guide/stop on TSR 2 (S2C needs no shifter cable), this isn't a straightforward hub swap. Therefore I contacted the Moulton expert Mr. Metras and he graciously agreed to do the mod for me. It took him only a few days to build the wheel and install everything, and the result totally blew me away. I'll let the pictures do the talking (from front to back):

    Shifter


    Cable stop 1 (secured with the front rack; if you don't have one, a bolt is just as good)


    Cable splitter (only needed for separable frame)


    Cable stop 2 (secured with a Herbie Clip)


    2 cable ties


    Click box and hub (dust cap not installed—space too tight)


    Ta-da!


    The gear range is now 251% (32, 40, 51, 65, 81), much better suited for the city's famed hills than S2C's 138% (51, 70). The clicking sound P5 makes is more muted and pleasant. The braking "feels" much nicer as well. While the new hub is heavier, the lighter Velocity rim that Bruce used to build the wheel cancels it out. All is all, this is very nice upgrade. I highly recommend anyone who wants to give his or her TSR 2 a boost contact Bruce for a quote.

    One thing I forgot to mention: P5's axle diameter is thicker than S2C. Thus, the axle hole on the pulley guide (snubber arm) needs to be drilled larger.

    Bruce is the Maestro of Moulton. You couldn't have found a better guy to work on your bike.

    Bruce has just a few major flaws.




    One, he has no ugly bikes.


    Two, he does not live in Melbourne.


    But he's still a maestro.

    SRAM announced almost a year ago that the wonderful P5 hub would be going out of production. It might already have. They've certainly quit marketing it.

    I should think the Sturmey's XRC5(W) five speed coaster brake hub could be made to work in a 120mm OLD steel frame.

    I posed a question along the same lines to the SRAM buyer of a major US wholesale supply house .. the freewheel and drum brake versions of the P5 were discontinued over 2 years ago.. he continues to order the P5 Coaster, which is still being supplied... I hope the new SRAM IGH facility in Taiwan will produce a suitable replacement for P5 .. it is such a nice hub.

    The XRC5 could be made to work .. just not as elegantly, with the SA OLN at 127mm and the P5 Coaster at 120mm .. so frame spreading or nut whacking .. also, the Sturmey is heavier .. a larger issue, the major SA suppliers in the US either don't list or stock the XRC5(W) .. I may buy a few more P5s to put on the shelf

    Yes, it's sad news that SRAM is phasing out the old trusties (T3, P5, and S7). I don't know if they will introduce new 5 or 7 speed hubs; but even if they do, the new version probably wouldn't work for 120mm OLD. The i3, which replaces T3, is of 130mm OLD, and i9 135mm. So it looks like SRAM is abandoning the 120mm standard.

    It was a pleasure working with you and your bike (absolutely spotless machine with careful attention to detail).. glad you like it ... I loved the 30 miles I put on it during testing .. so much so, that another one is in the works..

    There were lots of things that worried me before embarking on the crass-country move. One thing I surely wasn't stressed over was the maintenance of my TSR. I knew it would be in good hands. Bruce is da man.

    biketoolsetc lists the XRC5(W) and has had them in stock in the past.

    Duly noted for Spring '12.

    Too cold now. Heck, it's in the 50's in the daytime here.

    Seen others add a schlumpf 2 speed crank,
    2.5 reduction gear or 1.6 or 2.5 overdrive
    so still not needing any cables with kick back shift 2 speed coaster hub.


    read SRAM has began the final closure of the last of the German Sachs
    manufacturing facilities , and shipping the machinery overseas.
    making some products just will not be restarted in Taiwan.

    In Moulton parlance, it was the Model 50

    On this board, Jur has 'been there done that' ... as well as myself..

    I "am there, doing that," with a genuine Moulton 50. It's been a little rocky getting the Schlumpf SpeedDrive dialed in to begin with. I'm waiting to clock more positive miles before commenting at length.

    PERFECT riding weather. No wind in the afternoons, and don't have to cart so much water along. In the spring and summer you have to contend with those afternoon NW winds. I'm weak enough when it's calm!

    PS: Spring '02 is long gone. ;-)

    Only problem is the cumbersome shifting with this arrangement....

    I have an after-market Schlumpf Speed Drive fitted to my Strida and logged quite some miles on it. While I don't have experience using geared BB and kick-shift hub on the same bike, I can't imagine it being an easy setup to shift quickly and smoothly. But it can just my lack of imagination.

    Put the mountain drive and AW 3 speed together, 3to4 is 1-2 step,
    but both are planetaries so take place at any speed, even at a halt.
    a little more time than 7to8 in a R'off, but not really an issue,
    for a JRA pace rider ...
