in my 30s, the fat is consolidating! And this must stop.
My commute would entail an approximate 26 mile round trip from
Caerphilly to Cardiff (according to data from Google Earth). My
question is:
Do I need a new bike?
Currently, I have an old Trek 820 Mountain bike. I've had it around 10
years. It has been a great purchase. When I was in my early 20s, and
going through a (late) Holden Caulfield phase, I used to ride my bike a
lot to make myself feel better. And the Trek has never let me down. But
would I need a Road bike for a daily commute of this distance?
Soft knobbly tyres are exceedingly draggy on tarmac, and a mountain bike
has a more upright and consequently less aerodynamic riding position
than a road bike. Also, if your bike has suspension, this is almost
certainly parasitic on the road, and is costing you energy. On a
mountain bike unmodified, you are going to have difficulty exceeding
12mph average, unless you are very fit.
On the other hand, a pure road race bike isn't very forgiving of less
than perfect surfaces, so if some of your off-road sections are not
tarmacked, a road race bike is not the best choice.
There are essentially two compromises you could aim for. The cheaper one
is to fit slicks to your mountain bike and pump them up hard, and either
lock your suspension (if you have it) or swap suspension forks for rigid
- ideally carbon fibre - ones. This will greatly improve the bikes
performance on tarmac for a total spend of about £40 - £120.
The other is to get something like a cyclo-cross bike, and fit it with
slick tyres. Cyclo-cross bikes are designed for racing off road, but
with drop bars like a road bike. They are tougher and more forgiving
than road bikes while still having good aerodynamics.
Quoted message said:The
terrain would be a mixture of road and trail (the Taff Trail to be
precise). I think that a great deal of it is now tarmacked so that
should make things easier. I was thinking of getting an entry level
bike (after 5 minutes of research) like the Trek 1000. Any
recommendations?
The Trek is OK if all your off-road section is tarmac. If not, you'll
find it distinctly sketchy on loose surfaces. But we've had bad reports
recently of the wheels fitted to Trek bikes, and it might be better to
look at equivalent models from other manufacturers - there are lots of
good bikes of this class around this price point.
If you have any untarmacked sections, cross bikes you might look at
include
Trek X0-1 (a bit more expensive)
Specialized Tricross
Quoted message said:As for transporting clothing and getting changed - I have a locker and
shower available to me at the office. So I guess I'll cycle in 4 days a
week (eventually after I have built up some stamina!) and take clean
clothes in on the one day that I get the train in.
Good plan.
