Bike Check: Danny Hart's Cube Two15 HPC Mullet Race Bike
One of the biggest team changes of the off season was Danny Hart's departure from the Madison Saracen team and his move to the Cube team, riding alongside Max Hartenstern. A new team and bike see Danny with a completely different setup for 2021 although he told us at the NotARace Test Session that: "I am always nervous changing bike brands after a few years on a bike. This one is next level compared to what I was riding in the past."
Let's take a look at how Danny Hart sets up his race machine for the not racing in Schladming ahead of the first World Cup in Leogang less than a week away.

Contiuning over from his previous setup, Danny is still running a mullet configuration on the Cube Two15 and with that he has chosen a 29" Schwalbe Magic Mary tire upfront with a 27.5" Big Betty for the rear. Danny is also running Cushcore inserts.
For his cockpit Danny is running Race Face's SixC carbon bars cut down from their original 800mm to a narrow for DH 760mm width. The carbon bars are fitted to a Race Face Atlas stem with Burgtec's Bartender Pro grips.
Mounted to Danny's top tube it appears he was running some kind of additional timing device to keep an eye on all of his runs over the two days of riding. We have seen plenty of others riders with similar setups included mounting GPS trackers allowing them to later analyse different lines and generate a detailed breakdown of where a few extra seconds can be found.
A big new component on the Cube for Danny is the four-piston Magura MT7 Raceline brakes. In previous years, he has been running Shimano's Saint brakes while riding for Madison Saracen but for 2021 he will be running the German brands' gravity orientated offering. One intriguing difference with the Magura brakes is the use of four smaller brake pads (one per caliper), this is claimed to help dissipate heat better than just using the standard two pads configuration.
Even though a lot has changed with Dany's setup with the move to Cube he is still running a Fox DHX2 coil rear shock for his race bike.

Looks like a four-bar to me!
I remember when 27.5 first came out someone went to them and they were the best, went back to a 26 and it was amazing to be back on 26 because 27.5 wasnt quite right
Growth hormones...
Maybe with is F4R program he has gown taller, thats a new service they are offering, or is it training with 2 other shorter riders he now feels taller?
Probably the move I am most excited about this year, as many others are on the latest new fastest machine that they got a couple of weeks ago from their last years frame provider, where Danny has moved frame manufacturer.
1. Danny found out he was being cut by Madison/Saracen while he was getting ready for a race run, from the press release the company did (so professional!).
2. He never liked his Madison-Saracen bike.
Further evidence that bike companies sizing is on the small side
Also, One pad per piston to help dissipate heat?
My old corvette Z06 brakes had one pad per piston and the first thing everyone did for fast road or track was to change to a large single pad. In addition to an opportunity for a compound change, it provides more mass of brake material to deal with heat.
Not sure I’m buying that line from Magura.
However I will say I hear great things about their brakes and fully intend on buying a set, just not for that justification above.
True, but it was not the performance limiting factor in the car. That would have been me. Closely followed by the front end grip level.
Not sure of its relevance in regards to brake pad sizes but ok.
One pad per piston will take up more heat faster, but will also cool down faster where a bigger pad will take up the same heat, slower, also also dissipate it slower
Ah That helps my understanding, thank you.
Total surface area for speed of heat transfer - convection vs total mass for thermal conductivity (and capacity for thermal energy at a given temp)?
Individual padlets having greater surface area but lower total mass and the opposite for the large single pad.
I wouldn‘t say that the surface area is greater with the single padlets but you get the idea… also what @Tmackstab is totally accurate. You basically have a doubled servo effect…
protern.io/how-it-works
It’s used by the Swiss national ski team and many other Olympic level teams and athletes. I know in particular those who race ski and boarder cross find Protern.io extremely valuable as you can see how gates further up the course affect speed later on. Pretty cool tech.
