Still happily using Gripshift in its XX1 format.

Oval chainrings are now with the larger "diameter" in a different location. Biopace was all to cock!

Gripshift?

Shut your mouth. I love my Gripshift.

Can't say I miss bar-ends though.

I really like my sub fork and my softail.

I quite liked my flex stem too and my first gen look spds.

How about 1.5" rear tyres paired with 2.1" fronts.

One of the chaps I ride with LOVES and still uses flappy paddle shifters...with uber narrow XC bars.

Getting on his bike is, well, odd....

I don't know about a "dead end" - I quite fancy trying a HammerSchmidt on my Liteville.

Thread hijack, but has anyone used one and was it worth having?

The problem with a Hammerschmidt on most frames is that it's a granny ring plus an overdrive, so you end up with more anti-squat and loads more kickback. It'll be ok on some full-sus bikes but not a lot, especially all the 1x specific designs on the market, as pedalling will totally screw up the suspension action and when riding downhill it'll keep kicking through the pedals and losing grip due to the chain tension resisting suspension movement.

I had a PRST-1 and a PRST-4, the forks worked well but the spherical bearing on the bottom link needed changing on a regular basis.
I wouldn't mind having the PRST-4 back actually.

Avid rollermajigs copied the cog hog IIRC. Neither are really a dead end as SRAM have incorporated a roller into their rear mechs.

Avid Rollamajigs are great, they solved a problem which later mech design solved. Not needed any more but certainly not a dead end!

So the internet disagrees over whether it was just a roller to smooth out a tight turn, or actually changed the pull ratio.

Smoothed a tight turn. Its just a roller that got rid of the need for a lasso of cable hanging out back.

Lol at that ABS abomination.

Anyway - I really liked dual control.

the Internet is full of idiots.
The one pictured on this thread is a straight roller, there are also a number of different offset rollers available that change pull ratio so you can mix and match shifters and mechs.
There is also one to enable mix n match between v and canti brake types.

It certainly is, I think someone is confusing an Avid Rollermajig/Crud Cog Hog with this.

Shimano even did their own version.

The Crud Claw, to clear the crap from between your cassette teeth, still got a brand new one in a box somewhere...

How about Dr. Dew brake lever extensions, so you could pull your brakes from your bar-ends!
They knackered the ends of your levers & fell off without much persuasion...

Is it wrong that I'm seriously considering Di2 as it'll let me mount additional shift buttons on my bar ends?

I still use grip shift and it's great.
And what was wrong with quill stems and threaded headsets ?

Not really. The XTR rapidfire remote was actually a moderately good idea for the sort of racing that was common back then. It was just terribly executed. Each one of mine lasted about a month or 6 weeks before it got sloppy and stopped working properly, i had three of four of them wear out before i went back to just shifting normally. I know a few others who had similar experiences.

For Touring or sort of XCM racing (lots of fireroad), Di2 remote shifters is *probably* not a hugely bad idea.

Odyssey Aerator Seatpost. Was a seat post with a pump built into it. Still have one in the shed, guess it must be more than 20 years old!

You need a pair of flipping massive spanners to adjust them, as opposed to just a hex key? They're much heavier because they use lots more material to do the same job? You have to thread and maybe slot the steerer as well as cutting it down on fitting? They came loose all the time if you rode over rough stuff, like on an MTB?

Bloody dreadful design, modern headsets are waaaay better. You're right about gripshift though.
