Quoted message said:I currently commute through London on an old £150 Halfords mountain
bike thing. The top front gear is something like 40 teeth.
I am almost constantly in the top few gears except for some hills, and
believe that I could get some extra speed by going for a "proper" road
bike
You could, but for starters you could probably increase speed
considerably by training yourself to ride at higher cadences, which just
takes practice. Select lower gears but spin the pedals faster, and aim
to get to cadences of about 80+ rpm. Many people cycle about at half
these cadences, and it just leaves you nowhere to go on your gear
selection (as you've found).
Quoted message said:(reduced tire friction, higher gearing ratios first time i will
use cleats etc)
To reduce tyre friction on your MTB, change the tyres you have for
slicks. These will give you better grip on roads anyway, as well as
being quicker and quieter. Make sure you have them pumped up to the
maximum end of the inflation range.
As above, higher gear ratios aren't /necessarily/ a good thing. But for
a lot less than the cost of a new bike you can just fit a bigger
chainwheel... Similarly. nothing to stop you using cleats on an MTB,
many do: just fit "clipless pedals", get some suitable shoes and off you go.
Quoted message said:Is a drop handle bar better or worse than the hybrid-style flat handle
bar for commuting? (safety terms mostly - seeing oncoming lunatics
etc)
Bit of a non-issue, frankly. The main point of drops is to give more
positions, not /just/ getting your head down. Ride on the hoods and
you'll have a better view.
Quoted message said:It seems that Specialized, Marin, Giant are the main manufacturers
these days, and their road bikes seem pricier than the MTBs. Is this
true or are there secret, amazingly cheap road bikes that only the
initiated can find?
Try Edinburgh Bike Co-op, or just look through the Rags for stuff in
Last Year's Colours.
Road bikes from the above are only more expensive than the cheap MTBs,
look at the serious dual suspension MTBs and they're every bit as
expensive, if not more so, than the road bikes.
But start off by changing your tyres and pedalling at higher cadences.
You might find your MTB is rather better suited to the job in hand than
you thought. It still leaves the option of changing bike, and higher
cadences will benefit you on any bike and the slicks on the MTB will
make it better for stuff where the road bike is hopeless, like getting a
heavy load of shopping home.
