The next time I replace my chain I will replace my 9 speed cassette too,
it's looking worn. I have a Shimano 13-25 cassette now, will replace it
with a 14-25 (which adds a midrange 18T between 17T& 19T).


This cassette seems to be available in two models, a HG-50 for $31, and
an Ultegra for $96. The two cassettes are almost identical in weight,
only a 2g difference and are identical in cog configuration. For me, it
seems the obvious choice is the HG at $31. It is hard to believe that
the HG Ultegra will last three times longer than the HG, or shift three
times better. Is there something I am missing?


The cassette will go onto an Ultegra hub that is about 5 years old. Is
there any compatibility issue?


Yes, you missed a smoking (in store) sale at Performance. I just got
two Ultegra cassettes for $39 each. I see 270g for the Tiagra (HG-50)
versus 217g for the Ultegra at the REI site, but it is not clear which
gear range is being weighed. I saved probably 50+ grams which means I
am going to go really, really fast now! (particularly if I remember to
take the spare change out of my pockets and ride on the drops).


I checked the Performance site (and its evil twin, Nashbar) and the sale
is not on. I got my prices and weights from the Harris Cyclery site, but
50 grams here or there is not going to speed me up or slow me down.

Tiagra sounds like a laundry detergent. (Spellcheck wants to replace
Tiagra with Viagra! Maybe Shimano will have a line like that in ten more
years, as the boomers gear downward.)


Mine is called "Saint" :-) (Very expensive it was, too.)

By swapping chains every couple of weeks (rotating three of them - two
SRAM PC-971 and one 991), after about 9 months now, this cassette has
*just* started to skip if I get up and jam on it hard to sprint
through a yellow light or something. (I might try rotating four
chains next time.)



I would not in a million years pay full retail for Ultegra. Tiagra is
fine, although it probably has a slightly different carrier, plastic
spacers and poorer finish (unnoticeable after 12.3 miles). You would
have to be a real princess and the pea person to notice a difference
in shifting. In my opinion, your only reasonable option is the
Tiagra. I only got the Ultegras because (1) they were on sale at
Performance, and (2) they were on sale at Performance, and there was
nothing cheaper in the store in my preferred gear range. -- Jay

So what's your gear range? I am going to 14x25. I use a triple, and
don't need any thing lower for most riding, where I stay on the two
larger rings. Way back on my first 10 speed, I had 14x28 which was more
or less standard in the bike boom.


I'm in a different realm, as you have road gear and I have MTB (48-
tooth big ring), but anyway mine is 11-28. That's why I bought the
Saint (HG80) - it gave me much tighter spacing where I wanted it
(11-12-13-14) vs. the HG61 (11-13-15) that came stock on my bike.

The 48 / 12-13-14 are my bread-and-butter, meat-and-potatoes. The
48 / 16 or 18 gets me up most hills, but I will drop all the way to
36 / 21 or even 24 for some steep ones.
