People always forget that making a one off isn't very expensive

you are joking aren't you making one of something is quite possibly the most expensive way of doing anything that involves a mold or a machine

You could always have a frame made from tubes/lugs etc, with something that bares a passing resemblance to the iso-speed but doesn't actually work. Plenty of carbon frame makers could do that from tubes without needing molds.

OTOH, what she has obviously works. Maybe she actually want's a 75deg seat angle and it's not just a function of frame sizing. Remember it's taller people that benefit most form steep seat angles and putting the saddle forward to compensate for too smaller a frame is going to rob her of power so I can't imagine it's being done without a lot of thought having gone into it.

Taken from a 2013 article on Bikeradar about her cross bike:

“Because of her shorter femurs she runs a more forward setup. Her setback is only 1cm behind the bottom bracket,” said Trek Factory Racing team mechanic Matt Opperman.

I guess she could run a back to front layback, might look a bit less silly.

Re the idea of Batty's proposed one off frame, specilazed haven't made kalhavy a custom epic yet (he stated he rides the large instead of xl as the xl's head tube is too long) and he only ever rides the epic. Think as stated above one off carbon frames aren't that practical plus if works but looks a bit odd who cares, more tools than works of art.
Very clear kalhavy doesn't care about conventional set up. Always think what people on here would say about his set up if he was a regular joe (esp seat angle, 130mm stem etc).

Is it really that big a deal? Specialized seem to be able to knock out [url= http://www.bikeradar.com/news/article/pro-bike-tom-boonens-specialized-s-works-roubaix-sl4-36952/ ]custom geometry frames[/url] for the likes of Boonen.

Hardtails are one thing, a custom FS bike would be a different kettle of fish I imagine.

The headtube length as a reason for rejecting an XL does seem odd though. To me (off road at least) it's only really a function of comfort and weight distribution. If it were too high (within reason) would it really slow him down relative to riding with a huge layback and 130mm stem?

Emily's is low I presume in part because the forward seat position naturally tips her forward (the reverse of a TT bike, which is low first, thus necessitating a steep SA).

I'd spotted the stem, but not the saddle!

I wonder how much is really looking for improvements and how much is gamesmanship with Juju Abs.

"I've gone FS"
"So have I"
"I'm National Champ (again)"
"So am I (again)"
"I'm European Champ (again)"
"I'm World Champ (again)"
"I've got a dropper"
"I've gone 29er"
"I've got a new girlfriend who has more stripey jumpers than you"
"I've got an impressively manly 36t chainring"
...and so on...

I don't imagine for an instant that it's like that - they both seem like pretty good lads, but maybe, just maybe...

Nino runs dugast(?) tubs.

I think that Mavic are stuck in a slow product cycle, they have been caught out with the move to wider rims, by newer faster companies. But once they have caught up, they will probably do it well. I also think it is a mistake forcing customers to buy a wheel tyre package.

Personally I think skinwalls look shit.

Yep - but the discussion is about those Mavic/Michelin wheels above, which don't look like tubs to me.

I agree that skinwalls generally look crap though.

Agreed the wheel tyre package is daft.

Yes I think Nino uses dugast tubs. Trying both 29er and new tyres today and flatted twice. Imagine he'd have given absalon a run for his money if not.

Anyone know why grant Ferguson dnf'ed? Seemed to be going well the first couple of laps but then diasapeared

Edit. Agree with njee, the mavic Michelin combo defo don't look like tubs

I love these pictures. So weird that we have to go to PB to see them.

The size of the Eagle cassette looks silly for me. I'm really curious whether the pros need that range.

They're running 38's up front (which is about the maximum the bikes will fit) so 38/50 is about same bottom gear as 32/42.
Whether they 'need' it is largely irrelevant....they get paid to use it so we'll buy it!

so few riders correct their saddle to run level once the suspension has sagged.
(that is a 200mm travel rear end, isn't it ?)

Nino's tyres are certainly quite interesting.
Unbadged maxxis aspens - the interesting part is that aspens are made of paper whuch doesnt make them seem very suited to the rock gardens, and dont come in 3c compound. So does this make them an Aspen2 prototype?

@Shaggy, yes they need that range, the 50t allows a bigger chainring, which in turn gives higher top speed for tarmac finish line sprints.

Not sure why they are creaming themselves over the 38t ring, with a 50t eagle on the back it's roughly the same ratio as 32fr 42rear

Could be, frame *probably* isn't primarily designed around a single ring that big so clearances might be a bit marginal. And Nino has probably had that bike since the back end of last year and raced it half a dozen times or moire.

Hope that weight is with a bottle or something - not especially light?
Nove Mesto is a bit of a tyre killer isn't it. Might be running something with a heavier carcass.

Pink bike article suggested the new Aspens come in Exo flavour, so yes, possibly tougher sidewalls than the usual paper variety that'd be used for bike weigh ins

Only reason I say is as a mere mortal I can get just sub 10kg on a race fs with pedals and decent tyres etc. XX1 11sp not 12. Also no tubs?

Tubs = can depend on wheel and tyre sponsor. Some will let it ride, some won't. Also depends how good tubeless offerings from the sponsor are.
The advantages of tubs get smaller every year. Lighter wheels, better tyres.

And Sub 10 kilos at WC level, sponsors will not tolerate not finishing due to stupid kit decisions.
You've probably got a kilo of "must finish at all costs" margin in there.

And FWIW, a kilo extra weight on an FS MTB is pretty much an irrelevance. Escpecially when he's putting out 350+ watts.

Probably a chainline issue, as he can spend most of the time racing in the middle of the block, and he's paid to run 10-50 cassette.

That's kind of the whole point - the 50 allows them to run a bigger ring for a higher top gear for the sprint finish.

Yeah I get that, on the PB article they seemed to be making out only super fit pros would run a 38t chainring, but it seems to me it would be the sensible size to run (if you had the cash for eagle that is!)

Sure, makes perfect sense, just so long as you have quads like Greipel. For mere mortals a 32 or 34 still makes more sense.

Helen Grobert for example ran a 32:

Used to be common before the days of wide range cassettes, pick your rings to give you good gears for most of the race in the middle of the freewheel. (Road, not MTB, used to see some odd combinations on bikes of the more retentive types.)

So here it's probably to avoid spending a quarter of every lap in either first or 12th, with the associated risk of bumping the chain off due to chainline.

And obviously to psych out the opposition on the start line (and start line sprint)

DOn't really think thats true. I have weak little chicken legs and have not found a climb i can't get up with a 34fr 40t rear (on 650b admittedly so equivalent to 32fr on a 29er), whears I regularly spin out in fireroads. My natural cadence seems very low though - about 70rpm, anything over about 95rm and I feel like my hips are about to fall apart.

I run a 36T oval against a 10-40 at the back (XT 10-36 with superstar components 40 XPR). I get up everything except loose rocks or boulders like some bridal ways in the lake district. Started my 1x10 with a 32T but wanted more ummmff

I chose a 36T for the power and speed, when you hit that sweet spot on a smooth climb, you can just push it hard and drop everyone. Control is fantastic on climbs too when you're inching along and I dont spin out on roads. I recently bikepacked 100miles in the lakes but had a 25mile road ride first and clocked 16mph fully loaded. They say, the 36T oval gives you 38T power..

Schurter runs the 38t as he loves to drop everyone, the power he's got is immense and unless he's tired Absalon, who runs 32-34, can't chase. Remember Albstadt last year, absalon is spinning like crazy to the line, but Schurter inches past him grinding the bigger cog=win.

It must be very low, on 32/11 on a 29er I can comfortably hit over 34kph on flat and spinning down hill I've got to 53kph

90rpm 32/11 is 34kph on a 29x2.1
70rpm same setup is ~26kph, youd need a 42 on the front to get 34kph at 70rpm.

Anyway. What hasnt been pointed out is the jumps between ratios at the small end of the cassette is significant, so you want to stay in the middle and use the smallest sprockets for final sprint only, or you will be in the wrong gear and wasting energy (remember some of these guys are running power meters or train with them so will be managing their power output)

Likewise with 34-11 on 650b, on a recent 2km flat strava segment my average speed is just over 34kmph with a cadence of 90, that feels comfortable, however if I up the cadence a touch to 95ish i feel uncomfortable, just nned to train higher cadnces more although the only time racing I've found it an issue was at the fisrt national at PEmbrey.

Mathieu van der Poel is now going to race the Albstadt WC! Will be very interesting to see what he can do with a front row gridding. He must have been at least the second strongest rider in the field at Nove Mesto to get 8th from 90-somethingth on the grid, getting caught up in two crashes along the way.

Sure, makes perfect sense, just so long as you have quads like Greipel. For mere mortals a 32 or 34 still makes more sense.

I used to run a 38t (11-32 cassette and 26" wheels) in the Peak, my logic was it was mid way between big and middle rings, and I'd never used the granny. This was before 1x drivechains were a thing, before 2x even, and before the internet was full of people offering opinions on other peoples bike setup. It was also before I got fat and had to buy 36" jeans to get my legs into them rather than my hips.

As others suggested, it meant I spent 90% of the time in the middle of the cassette and 38-32 is still a significantly easier gear than singlespeed!

OTOH, I had a knee arthroscopy at 21 which may have been contributed to by a combination of pig headednes, that gear and Conduit hill!

How Mathieu van der Poel goes on a course with longer climbs will be interesting. Could be a good 3 way battle with Nino & Absalon.

Although Nino did run a 38 he was running very high up the block on the climbs on the weekend, that's even though he is a small compact rider, compared to many others.

Did you spot that tiny silver square on the inside of the fork arch? Many World Cup cross-country and downhill racers are sticking these silver-colored squares onto different parts of their bike, and while they look like tiny GPS trackers from a spy movie, their true intention is much more interesting. They're made by Axxios Technology, a Swiss company that says that their AXS Sensor System is able to allow a rider to go faster thanks to their tiny silver stick-on squares providing a ''massive reduction of the negative impact of vibrations of the bike.'' How much faster? ''Among the best racers in the world, the improvement is 1 second per racing minute; among amateur pilots, time saved is even greater, about 2 or 3 seconds per minute.'' Those numbers are no joke when you at the level of Mathias Flückiger, whose bike is pictured here.
Axxios says this is possible due to a series of small oscillating circuits (capacitors and inductors) inside the stick-on AXS Sensors that act as very fast access energy reservoirs. I'm going to let them explain how the system works: ''Whether in a solid, liquid or gaseous medium, the AX Sensor acts directly within the material by inducing atomic diffusion. It affects the electrical and mechanical properties of the material onto which it is bonded, by means of electromagnetic interactions. Effectively, because this material and the AXS Sensor are of different natures, a difference in contact potential is created at the interface, since the energy required to remove an electron differs between the two materials. All potential differences give rise to an electromagnetic field that affects the basic material: higher elasticity modulus, higher natural frequency, and reduction in amplitude of parasitic oscillations.''
More vibration control is said to equal less fatigue, better performing suspension, and more traction, but does it actually work? The AX Sensors are being used in motorsport, human-powered sport, and industrial fields, but I'd have to try it myself before becoming a believer.
