Thanks for all the information..
To answer Bills' question , I'm really just trying to maximize range while 
keeping the quasi-single chainring up front.  I believe I could achieve 
what I need with just getting a smaller chainring but I do find myself in 
the 40/12 often and I don't want to totally give up on a high gear.
The advice to look at % difference between jumps in gear-inches is helpful. 
 I'm now leaning towards a 10 speed Sunrace 11-40 and keeping all shifting 
pieces ..just means I'lll need to keep it friction.

I do live in a somewhat mountainous region *(I know the Catskills are more 
like hills to some of you*) and load my bike up pretty often ...and I also 
know that I can achieve what I need with a triple which I've been happy 
with all these years.  I'm just excited to figure out a system where I have 
a wide low double in the front without a front-derailleur where I'm in the 
Middle position of a 110/74 triple crankset 90% of the time and have a wide 
gearing range in the back that will keep me moving *most* of the time.

Thank you

Re: [RBW] Re: IRD 8-speed [13-40] Wide Range Cassette

[Patrick Moore]

I have to say that I sit on both extremes of the cadence spectrum, since
(a) most of my riding on pavement is fixed gear, and (b) I hate shifting
only to find that the gear I've shifted to is not exactly the one I wanted.
(But I'm someone who does obsess about gear ratios for fixed gear
drivetrains.)

For multiple gear systems, I prefer to give up high and low ends in order
to get 1 tooth jumps between gears in the cruising range. One of my nicest
gearing systems, back when I rode derailleurs on road, was a
"pseudo-half-step" with very closely spaced 48/45 or 47/44 rings and a 7
speed cassette that was something like (forget exactnesses) this:


*48*

*45*

12

99


13

91

86

15

79

74

*17*

*70*

*66*

19

63

59

22

54

51

30


37

Most of my riding was on the 17 t cog, and, with Kelly Take-Offs, I could
ride comfortably on hoods and in hooks and simply flick the left lever back
and forth for 9/10 of my riding; perfect indexing. The 12 and 30 were used
only with the outer and inner rings, respectively.

More recently, I've got this on my Matthews "road bike for dirt, with 29.5"
actual Big Ones for riding in our ABQ, NM bosque sand:


*42*

*28*

14

89


15

83


16

77


17

*73*


18

*69*

46

19

*65*

43

20

*62*

41

22

56

38

24

52

34

28

44

30

The ratios are perfect for my riding, which is along the acequia roads and
trails paralleling the n/s, flat terrain, Rio Grande, whose surfaces are
composed largely of old river silt. But since any ride is at least partly
pavement, I like the close ratios that allow me just about exactly the
right gear for anything I am likely to encounter on my pavement/dirt
routes; note that all this is also relative to my preference for a high-ish
gear, low-cadence, high-torque pedaling style.

But then, even with these systems, I probably shift less than most riders.

"I does make me curious what others may think is the ideal spacing between

I've never run more than 8 (and always a triple), so pretty far behind 
current thinking.  For general use & touring, 2 tooth jumps between the 
smallest cogs, going to 3 in the middle & 4 for the last couple shifts well 
and doesn't feel like stepping into a hole.  12-14-26-28-21-24-28-32 (or 
34) meets my needs.  I was cautious about the 28 to 34 being too big but it

[jandrews]

Thanks Phil
I'm glad to hear first hand experience. 
I don't typically ride in a manner where I'm trying to keep a constant 
cadence...I feel like I can make adjustments when approaching a climb. 
 Your feedback is very helpful nonetheless.
I does make me curious what others may think is the ideal spacing between 
cogs when climbing and shifting down while attempting to maintain a 
somewhat constant cadence.

Also, if I go to a 10 speed Sunrace (or other) I'd at least have to get a 
new chain and potentially derailleur ..so getting a few more teeth in the 
back might not be worth it to me.
Love the idea of gaining a 40 low end and keeping everything else the same.

Jason

[RBW] Re: IRD 8-speed [13-40] Wide Range Cassette

[phil k]

If you like to keep your cadence going up hills, I would try the 9 speed or 
even the 10 speed made by Sunrace.

I had the IRD 8 speed wide low cassette for help with climbing. However, it 
didn't help as when I'd go uphill, I would lose cadence because of the 
spacing, Climbing got more miserable with the IRD 8 speed wide low. I 
enjoyed my 1x9 with 12-36 cassette.

I am currently running 1x10 and like it even better. I use friction down 
tube 11 speed Dia Compe shifters
