Las Vegas Cirque du Cycling, Lap Two - Interbike 2017
@WAKIdesigns: Ah good, so we'll get proper wide rims for our 26" wheels.

Fastest Woman in the World - Interbike 2017
@bonkywonky: Let me try: why no bigger wheels? I expect they have trouble finding rims and tires certified for the speed she's going. And it was 17" rim diameter, was it? My experience was that a so called 20" bicycle rim actually takes a 16" moped tire (more or less) as the moped tire diameter refers to the rim diameter whereas the bicycle tire typically refers to the "expected" outer tire diameter. So yeah, what she's running may approach something like 22" in bicycle language. Why v-brakes? If she brakes, it'd be the end of her attempt. The main challenge will be to take all that heat. And a chunky rim like that is simply going to absorb more heat than the brake rotors we have in cycling. It may blow up a regular bicycle tube but it shouldn't harm a tire like this. Why the ridiculous amount of seatpost setback? In mountainbiking we've come to expect very steep seat tube angles because nowadays bicycle reviewers judge a bike by how steep you can climb whilst seated. So to compensate for that, seat tubes have gotten steeper. Same probably goes for road cycling. Climbing is critical. She's not going to climb with that bike so she simply chooses the seat tube angle that works best for seated tucking pedaling. And apparently for her that is what we see here. A seat angle not compromised for climbing (and not compromised for limited hip mobility many of us suffer from).

Pinion and Gates talk about their new partnership in the US - Interbike 2017
@lacanuck24: Thanks, that bike looks beautiful! For me buying local it would more likely either be from Portus (Krowd Karl), Olsen or BTR could modify a Ranger frame. Even though I love the concept by Steven Olsen, I don't see myself ride carbon but even that one in steel would be about the same kind of money. But yeah I'm now also wondering how much worse Rohloff would be. On a 2.5kg frame, how much does it matter whether you have an extra kg at the bb or at the rear hub? Those are durable too. And of course it means I can actually share it with a fully as long as I make sure it takes the same axle. Then the unsprung weight does matter but then I was looking at my fully. 600g hub (Fire Eye), 400 or 500g rear mech with axle (Shimano Saint 2007, no rapid rise but still axle mounted) and probably a 350g cassette or so. And it still works and it is not even that far off from a Rohloff rear hub. And of course it doesn't take such a big modification to the frame. Silly enough I usually find it easier to ride a hardtail. It feels more predictable so I trust it more to find it's limits. The fully is of course better at straightlining the rubble and climbing with less worry about traction, but I find it less predictable through corners. So if I'd get a gearbox, I'd be fine just having one on the hardtail as the fully doesn't get ridden that much. But yeah if you want Pinion on both bikes, it is going to destroy your life.

The 5 Most Popular Demo Bikes at Bootleg Canyon - Interbike 2017
Thanks all for the feedback! So can I summarize that the belt is probably less direct than a chain and the efficiency of the gearbox is marginally lower than for a regular drivetrain but not by much? @StackingItSince1991: I can imagine. I love the area around Rotorua, Taupo etc and I can imagine those who ride there regularly are going to build some skills and speed :).

@fartymarty: Not sure about the road bikes. One thing is what discipline you relate it to. Anyone can mount a triathlon handlebar to a road bike but you can't (and understandably shouldn't) use that in a race (or even traffic) with many other riders near. And I don't actually know whether pedal assist is mounted to (non commuter) road bicycles the same way we see it happen in mountainbiking. But to be honest I haven't looked enough into the scene to understand what is UCI approved and what people are riding. As for the dissimilar front-rear wheels, it is a funny one. I recall an interview with an UCI official. I think it was Dirt magazine with Chris Ball but I'm not sure. He said they are open to dropping the rule but they principally don't change rules for next season as obviously brands are already developing stuff for that season. So earliest would be 2019. Which is silly in a way because it probably takes more for brands to modify their frames to accept 29" wheels in the rear than it is to tweak the geometry to work with dissimilar wheel diameters. Even sillier of course is that this only applies to rim diameter, not the outer tire diameter. I sometimes wonder whether these people at UCI sometimes also smash their heads against the wall about all the bureaucracy and the way they've defined their rules. But yeah, that doesn't stop Liteville, Foes, Specialized, Banshee and the regular rider assembling their own bikes to actually ride the bike they believe is best. Some say racing is at the forefront but in reality, racing sometimes forces itself into a really conservative position.

Kali's New LDL-Equipped Helmet for $100, and New Knee and Elbow Pads - Interbike 2017
Yeah, surprised to see that from Kali who, with their helmets have a big focus on not getting hung up to obstacles etc. Surely these will get a sleeve of some kind over them to cover them up. Otherwise after one ride (crash) these will be filled with mud, the next ride you'll find them rigidly caked with stone which defies the whole point. Or these are merely for street (BMX) and road (racing) cycling. About time these road cyclists start wearing some proper protection too, for the speeds they're going at.

If the car in front of her hits the brakes, that will stop her too.
