I think Porte's wheel change delay is a good example of the downsides of discs in a race.

Should the neutral service carry disc wheels though?

hatler · « **Reply #252 on:** 17 September, 2020, 09:40:48 pm »

Are all disc wheels the same ? Rotor size ?

The brake will drag when they swap a disc brake wheel. Maybe we will go back to the days of the rider being dragged back up to the peloton by the team car while the team mechanic fiddles with ‘something’.

Why ?

Hot Flatus · « **Reply #255 on:** 17 September, 2020, 09:43:28 pm »

Slight differences between wheels. Need to centre the caliper.

LittleWheelsandBig · « **Reply #256 on:** 17 September, 2020, 09:43:40 pm »

The disc is never in the same lateral location and the clearances are so small. Rim brakes have much bigger clearances.

Cool. Thanks both. Can you tell I'm a disc newbie ?

I expect Ineo$ have a special mechanic whose sole job is to make sure all disc wheels match to within fractions of a millimetre

Ineos are riding rim brake bikes

No need to complicate the mechanical side of racing when you've got all those drugs to ferry around and tests to evade.

If the neutral service car wasn't carrying disc wheels it wasn't neutral.

Given the number of disc brake “ standards” it might have to be a neutral service lorry

The only support near Porte when he punctured was a neutral service motorbike which at most carries 4-5 wheels. There's more variations of disc/hub design than it can carry and it has to have front and rear so carries rim only wheels.

I don't know if the neutral service cars carry more than just rim brakes?

T42 · « **Reply #263 on:** 18 September, 2020, 02:31:16 pm »

I'd rather replace my wheels every couple of years that live with that faff. Last time El Prez had a bent wheel he was all of a tizzy because he couldn't find the wee spacer to slip into the caliper. Jeez.

Sivakov lost a bidon when he fell just now. I wonder if they'll fine hím 500 Sfr.

Not that many in terms of hubs and spacing. Tends to be 142mm rear 12mm axle. Front always 100mm and 12, but occasionally 15mm axle. Cannondale used to be rear QR but I think theyve abandoned that.

Discs can vary in size so, yes, in theory there are a few permutations, but in practice not so much.

It's probably more faff that it is worth for racing in the dry, although I was listening to Armstrong and Hincapie's podcast the other day and disc brakes were their number one lament for technology they wished they had had in their era.

Neutral service only carry rim brake wheels for the reasons given above. Another win for rim brakes today, although some Sunweb riders seem to be on discs.

Most wins have been on discs

Tres interesting, HF! I especially liked the bewilderment at cruiserweight riders climbing faster than a bantam Pantani - who was on speed anyway! It has all been a bit, well, incroyable, nicht wahr?

My French is just about good enough to understand this bit.

If they all ride 140mm it’d work ok.

Different width rims and you have to unclamp and reclamp the brake cable for rim brakes. Not that’s a faff!

There is a reason for a continuously variable QR and a barrel adjuster.
