Re: Chainring/spider question, which side?

I have always seen the gear on the outside and the spider to the inside

Re: Chainring/spider question, which side?

It may sound weird, but like in those pics, I tend to like running a spider on the outside and a disk on the inside. Just looks better to me if nothing else. Functionally, I don't know. You may want to decide based upon chain alignment one way or the other.

Re: Chainring/spider question, which side?

Most 'Old School' spiders usually have a recess on their tips
  that the chainwheel 'butts up against'-as it rides on top of the
  spider! I've always assumed that the purpose of these recesses
  was to 'help keep the chainwheel aligned' if a chainwheel bolt
  problem was to arise...i.e. 'come apart!'

      If you run the chainwheel 'behind' the tips of the spider-and
  a bolt problem SHOULD occur-the same 'alignment help' from the
  spider would NOT be available!

      I'm relatively sure the spiders were designed this way on purpose,
  but I'd also say that if the spider will actually allow 'either mounting',
  then the 'choice is up to the rider!'

      I think that 'appearence-wise',the chainwheels-most,anyway-LOOK
  much better mounted on top of the tips of the spider, rather than
  under them! JMO...

Re: Chainring/spider question, which side?

One other point...the 'power disc' your picture shows won't
  allow the chainwheel to be mounted any other way than the
  way you have it mounted!

       A power disc isn't 'really' a spider! A spider has legs...
  that's why it's called a spider in the first place,isn't it?

Re: Chainring/spider question, which side?

the chainwheel should be fited (in most cases) so its in line(flush) with the spider. to minimise twisting as you pedal,twisting reduses the amount of force transmited to the chain.so less power per pedal stroke. chainwheel and freewheel should also be in alinement but this should be done useing washers(shims) on the bb and or rear axel.

Unless the disc is backward?

Re: Chainring/spider question, which side?

It's not really "just a matter of preference".

MOST micro-freewheel (13/14/15T, aka "Metric") setups require the chainring to be mounted inside, to get the chain alignment straght.

MOST full-sized freewheels (16T and larger, aka British or ISO) setups require the chainring to be mounted outside.

One reason for this is that the teeth of most "micro" freewheels are closer to the center. Another reason is that "micro" freewheels usually screw farther onto the hub.

It works out on most frames too. Often, a big chainring can't be mounted inside without touching the frame, but a small chainring can. And you use a smaller chainring with a smaller sprocket, 39/14 has a ratio half-way between 44/16 and 45/16.

He's correct about the chain alignment. The best chain alignment from the freewheel with the chainwheel.

Re: Chainring/spider question, which side?

Depends on how sexy your spider is tongue . Most chainrings can be mounted on either side of the spider, with little effect on the alignment of the chain.

Take my set-up.

According to Crashman, I should have my ring the opposite way (on the outside). Every pic of Sugino 3 piece cranks I've seen has the ring on the inside. I mounted it both ways, and the alignment did not change appreciably. It has provisions to mount it both ways, but it seems most prefer to show the spider.

Rules of thumb don't apply to third thumbs :p I know that exceptions exist.
