GMC Denali Road Bike

The GMC Denali Road Bike is in the starter road/racing bike category. And actually it’s several hundred dollars less than you might expect.

But don’t let the low price mislead you, this bike is significantly more than you can expect at your local mega-mart department store. The good news is that a lot of people have purchased this bike before you and in turn one by one contributed to its quality trend analysis.

GMC Denali Road Bike

Road Bike or Racing Bike Features

The GMC Denali Road Bike is easy on the eyes, and has a well built frame with decent welds. The frame is much lighter than a mountain bike, but not as light as bikes costing several hundred dollars more. When it’s all said and done, this bike weighs in around the 29 pound mark.

While the frame looks great, it does have its flaws. The standard is tubular, and this frame is not on the front vertical. Why should you care? Because non-standard means its harder to mount accessories to a non-standard frame.

As with most road bikes, it has 21 speeds to make nearly any road easy to tackle. And the GMC Denali Road Bike really rides well, its gearing works well making it fairly fast without the big bucks. It’s more than good enough to make the daily commuter or daily rider happy, but for serious competitors, you’ll want to spend some serious bucks to stay competitive.

Alloy calipers and ally brake levers

While the calipers and ally brake levers aren’t the best, their significantly better than what you’ll find at your local mega mart. But the Calipers could stand to be upgraded as could the brake pads so that it stops as good as it goes.

Brake levers: Promax BL-250AP Aluminum
Brakes: Promax 501A Alloy Caliper Brake

As with the derailleur’s, the brakes need to be fine tuned. For the purpose of shipping and assembly the components come slightly loose and need to be dialed in. For people who aren’t sure how to do this properly, it’s probably worth paying someone who is to do it for you. It will make the difference between satisfaction and frustration.

The GMC Denali Road Bike uses Shimano derailleur and Shimano Revo shifts, which must be fine tuned as mentioned previously to get a great ride. If you can’t get it adjusted right, you’ll be blaming the bike, but really with a proper tuning, these work great.

There does seem to be a problem with the rear derailleur, as many have had to replace it.

Shimano Derailleur and Shimano Revo Shifts

Shimano has been making road bikes better bikes for years now, even sporting some fine bikes themselves, some of which you’ll find reviews on here in Road Bike Reviews. So when you see Shimano Derailleur and Shimano Revo Shifts in use, naturally you would assume that your getting some decent quality. However you need to understand that these aren’t ready to go out of the box. You’ll need to adjust them, even then they can give you fits and you may want to replace them. So they are Shimano, but the cheapest Shimano makes.

The shifter is a grip style which is likely different than what your accustom to unless your into mountain biking, as thats where you’ll normally find this style of shifter. The bad part is they take a lot of handle bar space which could be used for accessories.

700c Tires and Vitesse Rims

Tires: Kenda Black With Grey Band 700X28C. These are OK tires, but they seem to have a problem with blowing out the inner tubes, so before you put them together and air them, do some investigation. Check the wheel for sharp metal, from cutting or drilling which wasn’t deburred. These burrs or cuts can give you fast flats. Once you’re happy there is no sharp metal to puncture your tire, install protectors to protect the tube.

The Rims are Vitesse Alloy black 700CX14GX36H. Be sure to check these rims out for being true, prior to riding to save yourself some grief. Just true them up as a part of your assemble and you should be pleased.

Pros and Cons


Price is great for a road bike, looks good, nice style.

Included water bottle holder.

Easy to put together.



Wheels aren’t quick release.

Handle bars not adjustable, one position only.

Shifters are awkward initially, but not bad once you get used to them.

While the bike style looks great its harder to add accessories because of the frame.

Common parts needing upgrade are:

Front and rear derailleur
Break pads
Plus purchase of liners for tires

Final Thoughts

The GMC Denali Road Bike comes in a box, a well packed box, but a box. This means it needs to be tuned and adjusted when you put it together. You need to ensure the wheels are true, the Brakes are adjusted, the front and rear derailleurs are tuned and make sure the hub cones aren’t too tight and make sure everything is lubed that should be lubed. Again, it just came out of a box.

The Denali has a good frame and front fork, everything else is basically the lower end as parts go. The brakes are cheap enough to up-grade that you should fairly soon after purchase. If you’ve given it a good tune and adjustment, the bike should be a nice ride. You’ll actually be surprised how well it rides when properly adjusted. Oh and make sure to get the bike sized for you, a small detail that is critical.

Bottom line is this bike is several hundred dollars cheaper than most starter road bikes, even if you do some heavy upgrading you’ll still be a few hundred dollars cheaper than a typical local bike stop starter bike. Keep in mind these are lower end components, but from good manufactures, so they will still be better than your average department store bike in quality, except maybe the brake pads.

The Price and quality makes this an exceptional value for college students, commuters and casual bikers not looking at serious racing. Just be prepared to adjust or have it adjusted before cycling. Do that well, and you should be tickled pink with this bike.
