Which zipp bars are these ed, want to try them.

Zipp SL-88, 88 refer to the reach at 88mm long providing a nice platform to rest my hand on, I prefer the longer reach bar for one reason - a bigger range of position from riding upright on the flat to comfortably stretch on the hood.

You might find a long reach bar to be useful when using aerobar, allow the aerobar to be set further back.

The drop section is exceedingly long, really nice to shift your hand back and move your body forward.

Not quite sure which interview you refer to, I have lost count of them.

The XT cassette have an aluminum cog carrier that allow a much more evenly spread load, and preserved the aluminum freehubs, this picture should sufficent;

Now look inside a Tiagra cassette, all of them are bolted together, and have a much smaller footprint for the load, this is why you often see freehubs with mark on them due to this;

SMP is the finest saddle I've ever ridden on, I sit completely differently on it, instead of sitting on the sitbones, I sit on the bones where the soft tissues is in between, and surprisingly, it felt much more cushiony than the Brooks.

The Brooks, like most saddle put too much pressure on the soft tissues, despite most of it are on the sit bones, even with a large cut-out, the soft tissues still get pressured due to the soft hammock feel of the Brooks.

SMP is the stiffest saddle ever, and I got an even more comfortable carbon one that take the royal biscuit, yet the stiff saddle prevent it from sagging and changing shape.
