[RBW] Re: spacing between chainrings

2023-05-13 Thread Steve

Joel, for purposes of chaining I'd suggest ignoring the bash guard and 
reference your chainline as you would for a conventional double (the bash 
guard is irrelevant to tchainline considerations. If you happen to have a 
long enough meter/yardstick (or something like it) you can lay one end 
between the two chainrings and check which cog on the cassette the other 
end.of stick rests on. For a nine speed the "ideal" would be a right on the 
5th cog, i.e., the middle of the cassette. Anything fairly close to that is 
good. (Apologies if I'm belaboring what you already know).

*Suggest calling/writing RBW.*
I recall a Grant write up a few years ago comparing the Silver to the XD2 2 
and I remember something about spacers on the 74mm BCD posts.

 If the crank is on the bike, you can measure the distance form the end of 
the seat tube to the teeth of the Middle and Inner rings using paper cut to 
size, and then the difference is the middle to Inner ring spacing and 
verify if > 5mm.

Re: [RBW] Re: spacing between chainrings

Btw needing spacers on a Silver crank instead of having the spacing built 
in is useful. You can use really thin ones to get the rings closer for a 
double-ring-plus-guard 11- or 12-speed drivetrain.

Typical spacing between chainrings is 5mm.
However, it is all about the chainline.

[RBW] FS: modern cockpit and drivetrain for your Riv

2023-05-13 Thread Neil Doran
Hi all, I'm selling a SRAM 2x10 speed setup that I had on my Sam for a 
couple of years. It is a super fun setup and works great. It's all very 
lightly worn.

I'd like to get $350 for the entire setup, or see suggested la carte 
pricing below. Let me know if I am way off on price for this stuff! Buyer 
pays shipping if not local to the Sacramento/Bay Area side of things.

As far as trade the only things I'm looking for are a Nitto wavie bar, a 
quill bullmoose bar, and possibly some bar-top friction shifters or perches.

- 46cm Salsa Cowchipper bar (31.8 clamp) - $25
- SRAM Force Double Tap levers (2x10) for mechanical brakes - $100
- Velo Orange removable faceplate quill stem (31.8 clamp), zero degree 
rise, brushed finish - $40
-> or $150 for the entire cockpit as-is, which includes still-nice 
Brooks bar tape

- SRAM carbon crankset, 50/34, 172.5 mm arms, GXP interface with bottom 
bracket - $150
- SRAM GX long-cage rear mech with Wolf Tooth road link - $50
- SRAM Rival front mech - $20
- Sun Race 11-42 cassette and 10 speed chain: $20 or FREE to whomever buys 
the whole enchilada.

Oh sheesh, how about  "If the rings are not flush with where you place the 
spacers, well then you must add/subtract that distance from each other". 
Some chainrings are thicker than others. that said, it doesn't have to be 
exact, you simply don't want to use something much too thick, like a 5mm 
spacer !

The other possibility here is you're using a narrow 10-speed chain, it 
might hang up a bit between the middle and small rings on a Silver crank if 
the shift is a little lazy.

[RBW] Re: spacing between chainrings

2023-05-13 Thread RichS
Joel,

If this helps, my 8 speed setup is: Guard/44/30 — but with a Sugino crank 
(if that makes a difference). Shifted with a Claris triple. No spacers 
involved and works fine.
Perhaps try without the spacers and /or play with the adjustment on the 
derailer.

Best,
Rich in ATL

I've never had to use spacers on chainrings, but I've also never 
disassembled the aforementioned crank.  To my mind, if you need spacers on 
a crankset, you've designed something wrong.
