you certainly CAN... but things will get fucked up. this is an ISO crank that has been used on a JIS spindle. the pic shows the correct factory ISO bb - the crank arm is just put on, not tightened...

Dug out these when cleaning up the shed a while ago.
Top is road, bottom is track.

Sweet!
Dibs if you ever sell.

Lush!

111-4 =107 that’s not half of what I claimed that’s spot on for what I claimed.

Were talking about ISO cranks on JIS spindle, if ISO cranks sit too far out on JIS it would stand to reason that the opposite would be true and that’s what your picture shows.

Realised it was probably about time I changed my rear tyre.
The only spare I had was 35mm, my mudguards are 35mm so had to go. No bother, our summers are dry and predictable, right?

Meh. He's entitled to his Humpty Dumpty logic.

The inconsistency of axial location isn't even the worst thing about square taper cranks, so it's not worth getting too excited about an old wives' tale when it affects things which only belong on beater-grade bikes.

Have I at all been disrespectful in this discussion? Any reason you’re calling my logic “Humpty Dumpty”? No reason to be an asshole.

asshole.

Yeah I said he was acting like an asshole for insulting me. Before that point had I been in any way disrespectful or said anything that would warrant an insult?

(111-107)/2=2

asshole

It's the response I'd expect from a 'merkin after I called him a solipsistic philologist

(111-107)/2=2

I never said 4-5mm a side, I said

You CAN fit a ISO crank on a JIS spindle, it’ll just stick out 4 or 5mm more then the bb measurement.

We don’t measure BBs from center out, we measure the overall length due to some BBs being asymmetrical. So I stand by 111-107= 4 which matches up with my original statement.

You said
“My Royal H has a modern TA crankset I ran it with a 107 Shimano BB for a few years, I tried it on another bike with much larger chainstays and the the ND side hit the chainstay. When I went to reinstall them on the Royal H I installed them with and 111 Centaur BB and it fits the same.”

Which implies you meant that the chain line, chain stay clearance etc were exactly the same, since as you put it we don’t measure BB’s from the centre out the difference between the two tapers is half the total difference between the two lengths I.e. (111-107)/2=2

But the overall difference is 4-5mm. Thats why I reinstalled it in the Royal H with a 111 ISO BB. If I thought that the change would have been 4-5mm per side I would have installed it with a BB in the 120ish range.

Dat stem, 170?

140!

Short legs, long torso?

The anti-rex?

The orangutan?

1.85meters
saddle high: 76.5cm from bb center. Not very short legs, nt very long torso..

My roadbike:

We have such a guy in polo too. Ride in a crouched position, massive saddle to bars drop and yeah super long limbs!

orangutan?

Gibbon. His height and saddle height are the same as mine, so he must have long arms :)

Awesome bike Tom!
