Gotta change the gearing... max allowed rollout is 5.46m.

OK. My son's bike is finished with the exception of handlebars. His track bars haven't arrived yet. Hopefully today or tomorrow. I also need to find a 16t cog to get his gearing right. At the moment, his bike is way under-geared.

I'm still waiting for cranks, seatpost, and stem to arrive for my bike. I went with the SRAM Omnium in 165mm. I decided to go with a 120mm stem and then try to match my road position as closely as possible.

Tires have been stretching on the rims for over a week. I'll start gluing tonight. My son gets his bike Sunday at his birthday party... just in time to begin a winter track program. He's going to be psyched!

Awesome Dad! :beer chug: Good crank choice too. I think you will like the 165 length too.

Off topic. There are a few weight weenies in San Diego. One does not post here often but we keep in contact. Get working on those climbing legs.

Mini-Me got his bike today. Still waiting for the proper track bars and a different chainring. We need to dial his position a bit but I am waiting for the bars to arrive. He's a happy kid.

I also picked up a super-dork helmet for a steal. It matches his bike. hahaha

That is great. Way to go Dad. I bought my son a BMX from Chain Reaction 3 months ago and it has been sitting under the stairs hidden until Christmas and it is killing me not to build it up and give it too him. I am going to WW it a bit for him and instead of baseball he wants to start racing BMX next summer. The bike will be fine for now and it was 50% off during Chain Reactions big BMX sale so picked up a $400 bike shipped to Canada for $200 including shipping.

I think it is great when a father that loves bikes can pass on the passion by showing their child the joys and love of cycling while not pushing it on them. Great work TED.

Thanks. Let me know if you need any tips on the BMX project. I have become an expert. Mini-Mini-Me is just starting to learn to ride and will start BMX next year. It has been a blast sharing the bikes with my older son. I'm looking forward to my little one joining us.

I used to race ages ago and he is so pumped up about racing instead of baseball. He is currently on an 18" wheeled bike but I have him on a 20" now. He is incredibly strong on the bike and has been jumping and bunny hopping very well so now it is just more about technic and learning how to ride the course fast. He is 7 but will be 8 when racing starts. We have a lot of clubs around the are with a very large club about 30 minutes away so that is who we will contact and I want to take him out to their track and have him go around while I ride my MTB. Just want him to see what he is getting into. I will also get him a MTB soon set up as a 1 X 9 and have him do longer rides with me.

Biggest lesson I learned was to keep the cranks short so my son could learn to actually turn the pedals instead of mash them. Too many little kids ride mini or junior BMX bikes with 160mm cranks... which are often standard on smaller bikes.

As for the mtn bike, we found it was good to have 2 rings in front if only to have a bailout when the going gets really tough. However, shifting from the granny to the "big" ring can be hard for little hands.

Mini-me finally got to take his bike out to the track. We still have some adjustments to make, but he really enjoyed it. He was out there for 2 hours.

I'd wish I got into track/road racing when I was a kid instead of doing barspins and rails on my bmx. Great build dad!

Thanks guys. Nitto track bars just turned up in the mail. So now we can finalize his position. He is super-excited. The parts for mine have arrived as well. I only need a stem to build it up. Stay tuned...

The track bars had a slightly deeper drop than the road bars, but he really likes the feel of them. So we inverted the stem and all is good. I am leaving some extra steerer to allow for future growth. Back to the track tomorrow. More photos to follow.

Ted, the Facebook pictures are awesome! Makes me wish I had one the same when my daughters were younger.

Thanks. Just got back from another training session. My son was a bit frustrated riding with older and faster kids. I put him on restricted gearing per national regulations but it seems I am the only parent to have done so. Most kids were running HUGE gears. I asked the coaches about it, but they said it doesn't matter if it isn't a sanctioned race. I'm torn as to whether or not to leave him on the restricted gear or let him run the tallest gear he can turn.

Since you have a flip flop hub, you could have a junior legal cog on one side and a larger one on the other.

Or, you could get a cheap rear wheel that has bigger gears for training and keep Jr. Legal gears on the nice deep wheel.
