I am thinking of changing OEM tyres for RockRider 5.2 to semi slick or
slick tyres. Want to know whether some one have tried to something
like this, if so pls share your experience. If not then please share
your expertise on my thought

I have a 5.2 too. Love the tires so so much. I sincerely hope u don't change the tires . The stock kenda tires are awesome! I love them.

On a more serious note, at an average cadence of 80, if my average speed is around 20kmph, how much will the slicks help me increase the speed at the same cadence? Any thumb rule anyone?

Sorry for ot, answer my question and suggest tires for the mail below pls :)

Hi

you can find those with Wheelsports -venky or at BOts-check for the
availablity,

i'm using 1.5 kenda khan bought from venky, don't think of the cost
for which you will never regrette...,
if you are aware with 1.5 semi slick you can still use the 2.1-old
tubes and its ideal for commuteing within the city-no need to change
them untill if you are going for semi slicks of 1" or 1.25.

experience : i have been using them for last 7months-haveing done
TFn09 and couple of 200+ and 100kms and also everyday commute to
office around 15kms.

Kenda rocks all that i would say...,

Same cadence, same gear, same speed. Irrespective of tyres.

Agreed - but with semi slicks you should go faster since there's less rolling resistance from the huge nobs on typical mtb tires.

Hey, thanks. I'm also looking for 1.5 tyres for my trek 4300. What I
observed was that in the cold mornings or dusty roads, I can manage
the 2.0 tyres. But in hot noon or afternoon on a black top tarmac, the
rolling resistance becomes a lot more significant and even on plane
surface with the same set of tyres, my speed reduces by at least 20%.
And I start looking for some dust on the side. Otherwise, 2.0 is fine
unless I would want to go for racing.

I'm also not sure if I can fit 1.25 or 1.0 tyres on the same rim. If I
can do that, it will be best for me, because I would anyway use 2.0
for most of the time and it is only on occasions that I would love to
race and switch to those slick tyres.

i.e. u'll be able to ride at a higher cadence easily / at a higher gear

Absolutely no arguments there but like Sudhir pointed out, to go
faster either the cadence has to go up or the gear ratio.

Was just pointing out [though it might seem obvious], that at the same
cadence the speed will remain the same.

Yes of course you are right. .... I figured he was trying to figure out any tangible benefit to riding semi-slicks.

So it just makes it easier and not necessarily faster by itself. . Not interested :p

To be painfully clear:

For a given cadence and circumference of tire the speed will never change.

What will change with different types of tire compound and tread is the amount of force required by the rider to pedal at the same cadence.

Hence, my original, although poorly communicated point, that you will be faster on a semi-slick tire vs a knobby mtb tire since for the same amount force the wheels will move faster.

Hope this helps and sorry for the confusion.

"lick tyres on MTB just makes it easier to ride" am confused with this
statement :(
if u riding easier means you r riding fast isn't it ? I am not
comparing with road bike. (atleast, if I am riding easier, I can do
long rides without much effort ?)
But will "non-slick Vs Slick tyre" will be faster ? Atleast in Uphill
on tarmac will it improve the speed?
My average speed is b/w 17 - 20 KMPH, When I was riding on Nandhi
hills my speed was B/w 9 to 11 KMPH will this improve if I switch to
slick tyres?

Balu

with Slicks you will be able to paddle faster and thereby increase your speed, if you continue to paddle at the same rate as before, there will be no difference in your speed!

There are 2 conditions being discussed here.

1. Cadence is kept constant,same as that with your old average on
knobbies. Nothing changes in terms of speed. BUT, with slicks, the
force required to maintain this speed decreases.
2. Force exerted is kept constant,similar to that you exert while on
the knobbies. Your speed increases.

Now, may I please have my A+ and complimentary book coupon? :)

I'm not sure how much the tarmac temperature contributes to the  slowdown. More likely, the higher temperature will reduce the amount of effort your body can exert as otherwise you will overheat. In addition, it's quite likely that by the time its afternoon, you'd have been riding for a few hours, so naturally your energy levels will be lower than the morning.

I'm pretty sure of this temperature thing with tarred roads. It is not
because of tiredness. Tarmac roads in the afternoon gets really hot
and I can see my front tyres rolling with full blackness. I can also
hear much louder tyre noise while rolling, as if I'm cruising in a car
at high speed. If I find the side of the road with little bit of dirt
as is common in Indian city roads I take that path and it rolls good.
Similarly if the tarred road had been wet due to rain a while ago or
due to some water spilling, it will again roll much better.

I think this difference in resistance due to temperature should become
less significant with leaner tyres. That is my assumption

when the temperature increases, the tarmac becomes softer not as firm/harder as when the mercury levels are down,
so this softness on the road makes the difference in rolling tires...

Yes, I think you get the award for the most 'lucid' explanation - LOL

Wonder if 'lucid' is the right word?

Yes but ....

You also have to factor in the effects of the increased tire pressure as a function increasing temperature

As well as the change in air density as a function of temperature change

And ... on and on.... Etc, etc...

Guys, Just to draw a Summary :

Slicks will improve your performance (No Comparison with Road bikes).
I can conserve my energy more efficiently... :)



Can somebody tell me in numbers : My uphill ride with full force my
speed was 8 to 10KMPH, so with slicks can I achieve 10 to 20%
improvement in speed ? means
can achieve 12-14KMPH speed ? and same in flat road at-least can I get
edge of 5KMPH average when I am peddling at full force ?

Balu

When I changed to (2.1") semi-slicks on my MTB, I noticed a ~5-10%
improvement in average speed, over 1hr of riding on flat to undulating
roads.

Not alot of change in hill climbs as you're fighting gravity more than
the road friction. Yes it would be easier on the hills, but only
slightly.

If you're going to be doing alot of city riding (commutes etc), slicks/
semi slicks are well worth it.

Cheers

Too many factors to just quote a number... Not mention the placebo effect.

this is my experience

Its more of experince that one have to go through to really find the
difference between the two semi slicks and knobbies

yes definetly it reduce the effort to cover the same distance on
knobbies

speed definetly depends on cadence and the wheel diameter,crank, gear
ratio that you select..., you position on the bike (angle of attack
with the head wind)not be compared with road bike.

just forget all those fundas and ride happily all that you can term is
it reduces your effort..., so proportionally one can take it with the
effort(energy saved) to distance covered with given time. or
effort(energy saved) to the speed achived at a given point...,

on the tramac issue: what i belive when the sun is at its peak in
summers-the tar flows awaya from the jelly(stones) there by increases
the traction with tyres what ever it might be (semi slick,roadie or
knobbies) there by reduces the speed

or if the tramac is in semi solid condition like a jelly,it will allow
you tyre to sink(resistance reduced) in which there by increases the
effort (imagaine riding on sand)

If try riding on the white shoulder line,which offers less traction
than the tramac road you will experience the difference in the effort
level that one has to apply.

Ideally that should have been the case if the road was not tarmac,
though the increase in air pressure due to temperature would be too
negligible, say a couple of psi.
