Part 1: Renewing a 2007 Specialized Stumpjumper Pro DIsc - Little Stumpy Touch-up Paint

Part 1: Justifying an Irrational Decision - Rebuilding a Bike Ready for the Scrap Heap

I tend to write very long blogs. I really appreciate when my Spark Friends can actually make it through one of my meandering blogs - and still have the energy left to leave a comment.

I am going to try to make this short.

I am in the process of rebuilding the first good bike I ever bought, which is a Candy Blue 2007 Specialized Stumpjumper Pro Disc. "Little Stumpy" is nearly 8 years-old, which is about a bazillion in bike years! All of Little Stumpy's brethren have long been recycled and turned into pop cans and aluminum foil.

I hate to see a bike tossed aside.


I have seen bikes sitting on scrap heaps. I think about when the bike was brand new and how the first owner felt when they took that fist ride. Was the bike a present? How many miles had the bike seen?

In the end, I just couldn't see such a good and faithful bike as Little Stumpy being tossed on the scrap heap. Little Stumpy is just too special, no pun intended.


Part 2: Rolling Back the Years with Touch-Up Paint

The heart and soul of any bike is the frame. Unfortunately, Little Stumpy has seen a lot of use and abuse. Little Stumpy was not designed for nice smooth roads. Little Stumpy was built for dirt, mud and crud. Little Stumpy is a battle scarred mountain warrior


This is shot of Little Stumpy's drive-side chainstay. This damage is the result of chain suck. The chain came off the small chain ring and jammed on the chainstay.

Here is the result of careful application of touch-up paint.


I mixed some Testors Model Master blue, silver and black paint to match Little Stumpy's Candy Blue color. I carefully applied the touch-up paint with a short-bristle medium camel hair brush. Using the thick paint and soft brush, I managed to fill the deep scrapes.

I think it looks pretty good!

Most of the paint damage was, predictably, limited to the drive-side chainstay. There were also some big scrapes on the head tube as a result of a few spills on rocky ground. I touched-up all Little Stumpy's battle scars.


This damage was causes by the chain slapping against the chainstay. Some of this damage was due to weakened rear derailleur springs. Some of this damage is also caused by fast shifts under extreme pedal pressure. Here is the results of the touch-up.


I may have to redo some of the silver pinstripes. However, the irregular pinstripes are really not noticeable. The frame looks new.


I am pleased with the results. I think installation of all the new parts I bought will make the bike look pretty nice. I hope the bike will ride better but Little Stumpy rode pretty well before.

The original Mavic wheels are excellent. I am installing larger diameter brake rotors for more stopping power. I am having fun renewing Little Stumpy.

Thanks for reading my blog.

    That looks sweet, nice job! Oh, Stumpy might be able to use one of these. http://www.amazon.com/Lizard-Skins-

    /B000YMI60A I have one on Starscream, been good preventative measure to reduce chipping when you get some chainslap.

    Glad You cared enough to put the loving touches to keep her going since she's such a good bike! Why throw away something that can't be replaced!

    Ha! I saw you used Testors paint, and the first thing I thought of was your other hobby. Looks good.

    (I was tempted to say "TL;DR" but that would have been incorrect)

    Beautiful!! Did you put some kind of top coat over the model paint so that it can stand up to outdoor wear?

    Nice job, Little Stumpy is looking good.

    The best bike I ever had was a 24 inch street bike that my dad pulled out of a ditch on his way to work. He had passed that bike for weeks and finally stopped and tossed it in the car and brought it home. He cleaned it up, oiled it, and did some touchup on the paint, straightened the handlebars, adjusted the seat and pumped up the tires. I was a happy kid that day. Good memories. Thanks for jarring them loose.

    Hey, why not? If it's in decent enough shape to keep riding, then why not fix it up and keep riding it? Besides, that's fun for you, so go for it.

    For the record, my bike is 26 years old (I bought it when my daughter was a year old and she's 27 now) It got fixed once when it got hit by a car, and it still rides great. Besides, nothing new is built to last anymore, so fixing up our old "stuff" is a great option.

    Little Stumpy thanks you! He has a lot of life left in him. So do you.

    Wowwwww.... Pretty! I wish I could fix bikes. That looks like a fun project! If 8 years is a bazillion years in bike years, is 3 years about 100 million?
