Building up a bike for my son

My son is turning 11 this year. Last year we got him a 24" Specialized through craig's list. It was sort of an impulse buy and I sort of wish we hadn't done it. It's beefy and like many kids bikes has too much crap on it that they don't need, such as a heavy ineffective suspension fork and chain guide. The brakes were crap as were the shifters.

We've been him riding on some trails and he was belly aching away. I'm tired, I'm having trouble shiftin, I'm having a hard time braking.... We'd sort of chocked it up to the typical 10 year old I'm really a teen ager.

I took a harder look at the bike and was in a debate regarding redoing all the cable housings and putting some nicer brakes and rear shifter on it. It really was heavy and didn't brake or shift well. Instead of putting any money into it I decided to just go ahead and look at 26" bikes cause he'd be growing into them soon enough. He already likes to ride his mom's bike around

Now the next hurdle was finding an affordable small bike that didn't look like a women's bike. No women's bike names, sky blue, pink or lavendar or flowers. I wanted a frame so that I could use some of my parts bin parts and then ebay the rest. This proved much harder to do than I'd expected.

Ebay was the only real venue. All the small frames were going for more $ than I'd wanted or were full bikes. Some that I'd seen that fit the bill for a short effective top tube included trek, Fuji, a haro, marin, specialized. But once you included shipping the costs were getting a little more than I wanted. Plus I just plain lost a few in the bidding process. Small frames are hard to come by.

But then someone at mtbr turned me on to some frames that performance sells. They picked up the older superslow Access frames and their own house brand. I emailed and got some geometry measurements (shown at the bottom of this.) Decided on the red Access bike. Sort of funky tubing but cool. ETT seemed short and the plan was to put a short 50mm stem on it with the goal of increasing stem size as he grew.

$149+shipping -10% discount coupon. Plus I could send it back no questions if I needed. I was pretty impressed upon opening it. They upgraded their powder coating process and it looked pretty cool. Light too. Note that it comes with a seat binder and crap headset cups (zero stack) I did order a Woodman zero stack just to be safe. A cheaper frame is there perf. brand but I wanted red

I'd had some parts and picked out the rest through some closeouts at Icycles, treefort bikes and ebay.

We gave a box of parts and the frame to him as an early bday present. But he had to help put it together. I must say it was really really fun to do it with him. Real father son time. He did a great job and helped with almost every part. I was a little bit more excited about it than him at times. Explaining each part in detail especially some of my prized parts bin treasures like my Real Designs Square taper Bottom Bracket.

I showed him how to grease parts

and press in the headset.

Scoured the Internet for some red platform pedals

He now knows Race Face and has brand loyalty to them over nike. As I have several other race face products. They had 50mm stem. Its a downhill stem heavy and beefy but cool.

We wrapped the chainstay and even put heat shrink tubing on all the cable ends

I'm pretty stoked on it. He loves it. 27'lbs with full disc. Heavy parts, front hydraulic disc, rear mech disc. WTB saddle, Sugino impel crank, heavy easton post, bar, nashbar rigid fork. The reach is good, but the big wheels make it a little on the large side. Sort of looks like a 29er. He'll adapt no problem and will grow into it in short order.

All in all, I'm really happy as is he.

Great hunt for the frame and excellent build for your son.

Father - son time in the project: PRICELESS!

Hopefully his enthusiasm and the new bike will delete the braking and shifting comments now while out on a ride. ;-)

Nice project... would like to do the same for my son. Do you have an idea of the weight of the newer 14" access frame? Local Performance has an older model that is real close to 3 lbs in the 14" size. Thanks for any info..

not sure of weight of the brand new one but I bet it's light. I was just amazed when I got the box that such a cheap bike could weigh so little.

For a kid's bike I think it's a big deal. It will help them a lot.
