davetapson Posted November 21, 2011 Share One of my mates reckons that a roadbike takes a 1/3 less effort to ride than a MTB. Is there a rule of thumb that says 'if you do a race on an MTB in so many hours, you'd take this many hours on a road bike'? Link to comment Share on other sites More sharing options...
kosmonooit Posted November 21, 2011 Share I wouldn't say 1/3 but there is a difference, maybe 70-80% of effort required on MTB Link to comment Share on other sites More sharing options...
Sammajoor Posted November 21, 2011 Share A MTB takes roughly twice the effort a road bike does..... Link to comment Share on other sites More sharing options...

It's a bull***t comparison.Think about it, if you are peddling at 100% intensity for a period of time it really doesn't matter if you are on a road bike or MTB or what ever. The fact is your HR and intensity is at max. So it's not about the vehicle, but the engine... Link to comment Share on other sites More sharing options...

davetapson Posted November 21, 2011 Share OK - I'll refine the question. If you can do 94.7 in 4 hours on a MTB with knobblies, what would your time be if you used a road bike? Same engine, same intensity. Link to comment Share on other sites More sharing options...
kosmonooit Posted November 21, 2011 Share Define - effort - Power? for a given power output you will go faster on a road bike than on an mtb (in general) For me that reflects in the awesome sub-5 times I cracked in the Argus on a roadie which are (generally) 70-80% the times I have done it on a mtb (excluding South Easter conditions) It also 'feels' faster: the position, the slinky saddle, the drops, they limited gears mean no taking it easy up the hills in a granny.

Witkop Posted November 21, 2011 Share To try compare the effort of cycling a mountain bike to that of a road bike has a large number of variables such as:terrianweightrolling resistance of tyresgearingopportunity for draftingrider position wrt wind resistanceext. In fact there are so many variables which cannot be logically isolated (within good reason, as no mtbker would willing cycle on tar for instance) that such comparisons are senseless and plain stupid. Which probably why roadies have such a infatuation on trying to make such calculations. THe best solution is to take your road bike to groenkloof or tokia and ride some single track.........

Soggy Posted November 21, 2011 Share Well it depends if your buddy is cycling offorad or on road. Rule of thumb for a newbie, on road stay with a road bike and visa versa for off road and mountain bikes. Although I cycled with some guys on MTB's and running knobblies and they were leaving some road guys behind on the flats!! Those guys were machines!

Same engine, same intensity. Ah - "A well defined question is already half answered" Now the question again is are you talking a R700 Game MTB and a R50k roadbike or a R50k MTB and a stuffed road bike.... So many variations, thus not easy to estimate. But you can look at roughly 15 - 25% improvement on your time (for a same 'price/level' of bike switch).

Same engine, same intensity? Link to comment Share on other sites More sharing options...
