unless youre comparing crank flex by riding the same frame but diff cranks within a 20 minute time frame, its moot. most of it will be placebo effect if you feel a difference on the same frame. frames flex so much compared to cranks that its damn hard to blame cranks first

Yeah but if you don't blame crank flex then you can't justify spending $300 on some blingin' NJS goodies now can you? :D Also your screen name scares me.

The 75 crankset is ISO, and according to Ben's the Grand Mighty is JIS. But it also says Sugino recommends using the 75 BB, which is ISO, with the GM.

I is confused.

The KyotoLOCO is nothing more than a (supposedly)limited anodized version of the RD/Messenger.

Wow I was wondering this exact question tonight. However I started a search on google first, expecting to do massive legwork to get the info out of these strange Japanese web sites that have been translated, and a million e-commerce sites that just quote the translated Japanese with no extra details.

Thanks for the awesome post RichPugh!

sugino 75 is not best option for all people.
