but even your idea of a disc very a non disc, your gear ratios with less resistance change too. if your disc saves up 1 km per hr say.... you need to practice your power at the same gear but holding 2-3 rpm higher to achieve the same power
Can you please explain this ?
A rider at Gear ratio 54, 15 at
90 rpm goes 40.8 km per hr
92 rpm 41.7 km per hr
You can either do this with more watts or less drag either was the chain to connect the rider to the bike must travel at this speed. So you should be used to the best ratios at the speed for top efficiency.
If course conditions are always changing in the real world so the rider must be familiar with the best possible way to get to their best speed.
And you are saying a rider has to ride his disc in practice sessions to get this right on race day ?
in all practice sessions ? No, but a lot of effort sessions sure. If you are racing above 40 km per hr you should practicing that, if you are doing a recovery ride hit the gravel bike.
Is that a new crazy concept!!!
Again blummenfelt in Milwaukee he says his best fitness of the year lost due to not enough bike time on his TT.
No. A poster (synthetic) said carbon shoes are akin to a speedsuit or disc wheel, to which you disagreed and came up with
"if your disc saves up 1 km per hr say.... you need to practice your power at the same gear but holding 2-3 rpm higher to achieve the same power . same as the shoes that = rest ground contact time" We are all entitled to opinions, but if you are going to flippantly start your post with "this shows you have ever"....you may want to get your facts right
That was towards that specific poster he has been ain’t carbon shoes for 4 years posting on them constantly yet never using them. How would he have any idea about training in them when he has never used them.
I have lots of data on himself with different carbon shoes and normal shoes. They are different not a lot but are. The two biggest factors are less ground contact time to keep momentum and bounce return for a longer air time. Hence why people can be faster in them.
I have a feeling you are wrong about the spin faster part to make up for a disc wheel at same watts... Hopefully bike experts can chime in
With a disc, you will go faster at the same watts (kinda the point of using one). To go faster you need to pedal the current gear at a higher rpm (increase cadence) or shift to a bigger gear (increase gear inches).
In the case of a rear disc, the cadence increase is small (~1rpm)....but you could get a need for a larger increase if the overall savings was larger (ex. disc + latex tubes + aero frame).
