Saddle Position

[Bob Cooper]

I’m wondering if members of this group have a fix for a saddle
position that is only about five mm off to one side but enough to be
irritating – chafing-bruising – on a long ride.

For example, one might put one of these

on the side with the leg that seems to be too long, thus making the
leg effectively shorter, pulling the sit bones toward that side of the
saddle.

Or one might find some sort of adapter that would fit between the seat
post and the saddle that would enable moving the saddle toward the
“short leg” side.

Without something to fix this, I’m essentially sitting on one, not
two, sit bones, thus effectively doubling the stress in that area,
which, after say six hours in the saddle, is not so great.

Any advice appreciated,

Bob

Hello All!

Just curious, can anyone who has experience with the new Shimano
'Dura-Ace' 7900 grouppo, offer up their opinions on it's performance,
fit, and any other, relevant issues? Likes? Dislikes?

I'm considering it for a new bike that I'm still hoping to get, and
am seriously considering outfitting it with this new grouppo.

If it helps, feel free to e-mail me directly at; pedalnut [the
ubiquitous 'at' symbol] bellnet [something resembling a 'dot' in
punctuation] and of course, the first two letters of our glorious
country. [... there now, that ought to bamboozle the spam bots!]

Many thanks!

Bill Taylor

I haven't used it myself, but you can read various reviews that all say
it's very good. I'd consider two things that make it significantly
different than the 7800 group.

1) It allows for an 11-28 rear cog (you can only do 12-27 on the 7800).
This pretty awsome. I have a 34-50 compact crank and I occasionally miss
my old 53-11 combo for screaming down hills. 50-12 tops at about
30-35mph for me.

2) Compatibility with your other bikes/parts. There's a great chart at
http://www.cycleslambert.com/download.php/?folder=Documents&file=DURAACE7900.pdf
that describes what works with what.

I guess I don't understand the chart very well.

Assuming I have Ultegra 6600 STI and want only the SD-7900 rear
derailleur and the 11-28T* cassette, it's possible?

If I follow boxes and lines, then it's a possible scenario.

Correct, according to the chart. Everything with a box is equivalent, even thought the 7900 line is not next to the rest of the components in a box.

My understanding is that the reason the you need a new derailleur for the 11-28 is because the RD-7800 can only reliably handle 27T due to pivoting range.

I've read reports of people stuffing an 11-28 onto their RD-7800 rear derailleur but I imagine it won't shift very well as doing it right, and why else would you buy DA gear other than because it shifts so nicely?
