Hey everybody! So as you all know, I currently ride a GMC Denali
700c Road Bike, purchased from a local Wal-Mart! (The pink cruiser in the background is the wifey's) And personally, I love
my bike! So lately I've been hearing some people talking about how
horrid of a bike it is and how it isn't worth upgrading. Enter Sir Flat
Broke Ironman to the rescue! Because, you see, I fully intend to ride
the Denali into the ground, until it's either totalled or my financial
situation improves to the point where I can afford a decent tri-bike! So
this is a quick guide to show you through what I intend to do with the
Denali in the next few years how to make your own clunker road bike
match the space-age bike snobs!
1. Clipless Pedals
If
you read my earlier review of the Denali, you know it comes with flats.
Which is a MAJOR problem as far as bike speed and power efficiency goes. I
understand the logic, most people buying an intro level road bike need
to get used to simply riding a road bike and that's much easier to do
without wiping out due to clipless issues. So step one for my bike and
hopefully yours, is going to be to install a clipless pedal system to
increase overall cycling power. I'm looking at installing these bad boys

Remember, you need shoes, cleats, and the pedals to make the system go!
I'm looking at adding this to my bike around late January or February.
2. Clip-on Aero Bars
This
is basically a temp fix until I can get integrated aero bars. These
basically just clamp onto your handlebars and adjust to a modified aero
position. I intend to install these at the same time as the clipless
pedals, all of which should help you (and hopefully me) look closer to
the athletes on $6,000 bikes. Quick tip: The same tape you use on
baseball bats works great on keeping sweaty hands from slipping on aero
bars. And it's cheap.
3. High-pressure Slicks and Presta Tubes with Adaptors
The
Denali came standard with 700x32 low-pressure hybrid tires. Not bad for
intermediate roads but definitely not race material. I'll be upgrading
these before my Ironman to high-pressure (100-120 psi) slick racing
tires. I'll probably be shrinking the width slightly too. The Denali
also came with Schrader valve tubes to make it more commercially viable
to a public used to Schrader valves, so those all have to go to be
replaced with Presta. And since the rims are drilled for Schrader, they
all need rim adapters ($0.65 on Amazon) to keep the valves from tearing
loose. High pressure tires reduce your rolling resistance and will help
make your clunker more aerodynamic.
4. Wedge Box Top Tube Bag
This
is more of an accessory than an upgrade and I'll probably be doing this
one in spring when I start going back out for extremely long rides
(they're only $10 at Wal-Mart) Another trick learned by watching the
father-in-law, he uses one to store immediate nutrition since reaching
behind you in aero bars is fraught with peril.
5. Quill-Stem to Threadless Adaptor
If
you own a bike with a quill-stem, you know what a pain in the arse it
is to find new handlebars. So to fix that problem, you can install an
adapter that then allows you to use threadless handlebars with your bike
which greatly opens up the possibilities. Eventually I'll grab one from
Amazon and fix my handlebar situation which brings us to...
6. Handlebars and Drop Bar Shifters
The
Denali comes with extremely heavy and heavily customized handlebars,
which have quite literally been cut in half to have mountain bike
shifters installed. So replacing these with carbon-fiber bars would be
an extreme improvement. Since I eventually intend to install integrated
aero-bars, the adaptor is a necessity and bar-end shifters are going to
become a must have. If you have some basic bike tune-up skills, this
won't be a major project but we'll see how it goes when I'm trying it
out! ;)
7. Deep Dish Wheels
This
is a long shot since decent racing wheels would cost me 4x more than
the bike did, but if you can ever find a great deal on a set of racing
wheels, you can greatly lighten your bike and decrease resistance. For
me, a new set of wheels would also be the easiest way to get
quick-release skewers on my bike!
8. Adjustable Saddle Post
Also
a long shot due to cost, but the straight-bar saddle post on the Denali
leaves the available positions somewhat lacking. An adjustable saddle
post would indeed fix these problems and allow for greater range of
motion but they're also expensive. Although speaking from experience,
the saddle post in the Denali weighs an entire pound all by itself so a
carbon-fiber post could shave some weight.
9. Drivetrain
The
Denali's drivetrain is somewhat lacking as the gear ratios and cassette
it uses are the same as for mountain bikes, topping off your gear-based
mileage at a sub-par area. When these wear out, I definitely plan to
replace the cassette and upgrade to a lighter, more weight-efficient
drivetrain. This is an excellent way to both gain gearing power and
shave off a few kilos.
10. Frame
Eventually,
if I have invested all this money already in the bike, I will want to
replace the frame with a lighter one to shave off the last few possible
kilos! Just remember, although the components may change the bike itself
keeps on living!
