I have seen plenty of high horse comments on this bargain type Walmart bike, and understand the poor souls who need to diss it.
The fact remains that it is an exceptional value.
For someone outside Titanium Club riders who looks for recreational riding a $159 road bike with passable frame and components may make very good sense.
If you are competent enough to assemble and tune it properly there is no reason it won't serve its purpose.
It certainly will show you whether you like road biking, and does not cost you a fortune if you find out that this is not for you. And if you love it, you may eventually head down to your local bike shop and endulge yourself with one of those titanium jewels.
I would like to hear from buyers who are not embarrassed to admit to buying a Denali GMC.
