My MTB Is Too Slow

Actually when I was cruising on my MTB (with knobies) the other day, I passed Stuart. When I asked where Lance was, he didn't answer. Apparently I was too kool. ;)

Yeah, cruise is one term that needs to be defined first. When I use this term myself, I mean a sustainable speed (within minor variation limits) over a certain part of a route. This speed could be equal, faster or slower than the trip's average speed.

Creative use of hypostrophes usually gets around such things. Try ****-ty.

I don't understand the difficulty with "my comments first, then his response". There were only two
paragraphs.

Which tyres?

How much did that cost?

In answer to your questions:

Tyres - Continental Top Touring 2000 700 x 28 A$36 each

Crank - Deore LX at about A$80 bought from the Internet over a year ago, as I have damaged my current chainrings I am now getting a trekking version (usually only available in Europe) of the Deore LX 48/36/26 from Cambriabike

Me too: to be 'crusing', the path must be mostly flat, since otherwise you'd be climbing or
descending. FWIW I'd define it as riding along reasonably flat ground, at a speed where you're not
really exerting yourself, but not going slow either.

An easy pace.

Which do you think made the greatest single difference, new tyres or a new crank?

MBC has the Deore Octalink crank in either 44-32-22T or 48-36-26(silver only). How does that compare
to the European 48/36/26 Deore LX?

This would be a good quality product but you'll probably need to get a new bottom bracket as this
is splined.

The change in gearing from say 42/11 (1:3.82) to 48/11 (1:4.36) is massive if your top speed is say
40km its going to be 45.7km with the new ratio at the same cadence (woo hoo!).

Where it all falls down IMHO is in the lower gearing with where say you might be doing 8km climbing
you will now be doing 18 percent faster for the same cadence. It may not sound like much but in
terms of effort and power output its a lot more.

IMHO and at the risk of sparking a riot I belivieve that cadence is everything, if you cant spin
it you cant climb it. Take a gander at Lance he eats em alive and its not just guts and grit. By
the way I'm not comparing my feeble effort to Lances I'm just an old fart who found a way to
save his legs.

A great combination would be 48/34/22 but where do you get it or maybe you can build it?

May all your cycling adventures be with a tailwind,

Neil.

I don't know. Obviously you'd need to be able to get individual rings, for starters, but if I could
get a new large Shimano ring I wouldn't have to buy a new crank, would I?

And which do you think made the greater, new tyres or a new 44/33/22 crank?

The bottom bracket is the spindle and bearing arrangement that your pedal cranks are fitted to.
There a few different types - Tapered square drive, splined and I think there is a variation of the
splined type. You can't fit splined cranks to a square bottom bracket and visa versa.

New tyres aren't going to change all that much unless your going from slicks to knobbies but then
you increase rolling resistance and are likely to loose speed because of the extra effort to drive
the tyres.

Have a look at Sheldon Browns site on all things bicycle it has a wealth of info.

http://www.sheldonbrown.com/gearing/index.html

http://www.sheldonbrown.com/k7.html

How many gears does your bike have?

Count the number of teeth on the sprockets on your wheel. Do the same for your cranks. Find out what
your tyre circumference is by rolling the wheel along a tape. Using the valve as the start and
finish helps.

Then go to - http://www.sheldonbrown.com/gears/

Have look at the gearing calculator then change the numbers on the chain rings to match the set up
you are considering.

May all your cycling adventures be with a tailwind,

Neil.
