>    * that ultegra/105 cogs are interchangable with dura-ace.
    Is this true? I was leafing thru a Co. Cyclist catalog, and I
    thought it mentioned otherwise.
    
    More to the point, how about staying with a 26, and going to a
    39 up front?

| 1965.2 | already at 39 | TEMPE::HUFFAKER |  | Tue Jun 11 1991 22:03 | 7 | 
|  |     I have already gone to a 39 front.  Funny thing you mentioned Colorado
    Cyclist, the person on the phone(at C.C.) when I was ordering some cogs 
    in the past said they were the same (they worked but then again I was 
    ordering dura-ace cogs, he said that was all they stocked but shipped 
    them to people who had ultegra).

| 1965.3 | It works with 105SC | RUTILE::MACFADYEN | Subtly modulated, richly textured | Wed Jun 12 1991 08:02 | 6 | 
|  |     I don't know about Dura-Ace, but I have a 7-speed Hyperglide 12-28
    cassette that I use sometimes instead of the 13-23. With a Shimano
    105SC rear derailleur, shifting remains very crisp. No problems at all.

I also use a 28 large cog with my 105.  The reason that it works fine is that
the 105 has a recommended msx cog size of 28 with a capacity of 28.

| 1965.5 | works fine | TAHOE::BUCHANAN | Bat | Wed Jun 12 1991 10:36 | 2 | 
|  |     I use that combination and it works fine.  I also use a 26 at times. 
    The cogs are interchangable.  The DA can only swing a 26 tooth cog.

|  |     You may be able to use a 38-tooth chainring up front, if you switch
    brands.  I heard of one of our European colleagues doing this -- maybe
    he can elaborate.

|  |     Re .6:  Me, maybe. I have TA chainrings on my 105SC chainset, including
    a 38-tooth inner, which is absolutely as small as you can get on a
    Shimano racing chainset. The 105SC front shifter handles the 52-38
    shift with no fuss.
    
    Another advantage is the TA chainrings are much prettier than stock
    105SC chainrings, which are quite ugly.

| 1965.8 | and another thing | IDEFIX::HEMMINGS | Lanterne Rouge | Thu Jun 13 1991 05:47 | 7 | 
|  | re .7  Not to mention cheaper......
My second hand Shimano 600 has a TA 39 on it.  TA boast 5 (or is it 6?)
different pcd's - I have read the numbers, but what do they mean in terms of
what fits which?  I'd like a cheap alternative for Campag Chorus - �25 is a bit
steep.  Or again for Campag Sport - I know Campag rings last for ever, but do I
care about that??

| 1965.9 | Suntour Superbe 38 tooth chain ring | TEMPE::HUFFAKER |  | Thu Jun 13 1991 18:20 | 6 | 
|  |     I have a Suntour Superbe 38 inner chain ring which I just put on.  Per
    Frank Berto's book "Upgrading.....(forgot the rest of the title)"
    It shows the Suntour as being harder than the Dura-ace.  Got it through
    a local bike shop.  Paid $19.00.

|  |     The book is called "Upgrading Your Bike". It does not cover the Shimano
    and Campy new stuff (Integrated 8, Double pulley brakes, etc... ) But
    it is a great book for bicycle gear heads. I read this thing from cover 
    to cover.
