i may be reading this wrong:

9 Speed Compatible: Precision shifting for narrow-spaced 9-speed cassette sprockets. 11-Tooth Pulleys: Alternating contact with chain links reduces wear, larger pulley diameter runs smoother, lasts longer.
Speeds-9-Speed
Max Sprocket-27T
Min Sprocket-11T
Front Difference-22T
Total Capacity-37T
Parallelogram Spring Adjuster-no
Guide Pulley-sintered alloy bushing
Tension Pulley-sintered alloy bushing
11T Pulley-yes
Bracket Body-aluminum/clear coated
Bracket Body Pivot Seal-no
Plate Body-aluminum/clear coated
Plate Body Pivot Seal-no
Outer Link-aluminum/clear coated
Inner Link-steel/pearl bright
Sealed Link Pins-outer link
Link Pin Bushings-fluorine coated (2)
Outer Plat-aluminum/anodized
Inner Plate-aluminum/barrel
Silver or Black.

230 gms for 25 bucks, i figured is better than 100 for xtr or ultegra... i'm looking for best bang/buck ratio and not necessarily "race bike" stats. so yeah, i think it'd be a good choice...

You'll likely have to be careful about your shifting with the 105 since most bikes are 44-22 and 11-34 geared which would conventionally need a teeth capacity of 45.

Shimano rear derailleurs have lacked a tension adjustment on the cage springs for years. They vanished in the light action switch from torsion springs to coil-springs during the mid to late 90s as all the groups got updated.

ok, sounds good.

and yes, i'm using an 12-27 ultegra cassette already.
Hey, drunkle, what ever happened with this? I ask because i've finally decided to make the switch to 9-speed on my NRS and found a deal from a european rider. ;) I figure getting it under 200 grams won't be a problem and to me that just adds to the bang-for-the-buck - inexpensive, proven, reasonable weight and still tuneable. ;)

yes, confirmed weight is 228g for the short cage model I had on my trials bike. Room for tuning, cheap too...

:)

Have fun !
