A Really Compact Ritchey Crankset

rocketman58 said:

I have a cold forged Ritchey crank that sports 41,30,20
rings. How's that for compact? Set up with three rings, it
still weighs about 625g. Ya, I know it's not the same
"compact" as everyone has been talking about here, but if
ya need real low gears...

...and if you don't mind a little chainsuck...

I have a 110 XTR crank with 48,34 that I have been using
for a number of years. It is one of the best 110's ever
made, in my opinion. I have even used it with a 46,34,19
combo (19 via a MT Triple on the inner location.)

It probably *is* the best 110 crank ever made. Cold forged,
polished, etc. I've never heard of one breaking, especially
with people who have broken several other cranks.

I hope we start seeing a lot more quality 110's become
available. It was getting hard to find them for a while.

Sugino has always made them. Ritchey and others are probably
made by Sugino anyway.

I know they were for lots of years - suppose they still are.
I've been running Ritchey cranks on my own MTB forever -
they're really, really beat up but I can't think of a good
reason to "upgrade".

These go for a lot of dough on ebay.

They seem to be coming back some. Folks recognize there is
no apparent disadvantage, but yet some advantage. I wonder
how many new bikes will come with them OEM. The last 110
road crank that came on production bikes was the RSX model
-- it wasn't bad for a entry level component. Keeping 110's
as simply aftermarket items will lower the total quantity
greatly. We'll see how it shakes out.

The square taper Ritcheys are Sugino. That fact is not
attempted to be hidden. Sugino is embedded in Al on the back
side of the arms. It too is cold forged and highly polished.
Very high quality. I think it is about 550 g without
rings/bolts -- about the same as Dura Ace of the era. It is
low Q, about 139 to 142 depending on the spindle. Sugino
made the high end Suntour cranks too (Superbe Pro & XC Pro,
and others).

Just received the first Energy from FSA. 34/50 double weighs
567gm. ISIS-108-200gm. Sweet. Tom

In my experience (riding for almost 30 years) chainsuck is a
product of excessive drivetrain wear and/or poor
maintenance. I have only sucked a chain one time, and it was
due to a worn alloy 28 tooth ring. I have never sucked a 20
tooth ring, even with a narrow 9spd chain. I only use steel
20 tooth rings since the alloy ones wear too fast. I have
even used "rings" as small as 18 teeth (adaptors using
cassette cogs) and never had problems with chainsuck.

Two things:

Smaller rings wear faster, because of higher torque and
chain tension, and fewer teeth to spread the wear among.

Second, the further you bend the chain, the longer it takes
to bend it back. This is especially true if the chain is
dirty. There's a good reason Shimano chose 22T for its
Compact Drive instead of going all the way down to 20 like
Suntour. They wanted to match Suntour's marketshare-
garnering "innovation," but still keep shifting reliable.
This was tested to death by Shimano engineers. Back in the
day when high end mountain bikes all came with Suntour, the
Suntour riders piled up at the base of all the hills,
stopped dead by chainsuck. XC Pro came with steel inner
rings that didn't wear much, but they "sucked" even when
brand new and relatively clean. Ritchey even came up with
the 2x9 system to eliminate the inner ring entirely,
especially for muddy riding. Middle rings or larger inner
rings can suck too, but the smaller you go, the more prone
you are -- and that's a fact. Note that Shimano has stuck
with non-Compact sizes for their flagship group, XTR.
