JKS mid build

Wednesday, June 24th, 2009

I’m just over 1/2 done building a JKS for James and it’s coming out very well. Some bikes are work and others just seem to fall together  and this one falls into the latter category. I should have it all done late tomorrow and then it’s off to JB.

Stay well,

Dave

Riding tip

Friday, June 19th, 2009

I wrote this about a year ago for the V Salon and it has been on my mind again due to a conversation going on on Road Bike Review. For those that haven’t read it I give you my take on getting the proper fore/aft saddle position. Thanks for reading,  Dave

Riding tip #2

#2 and then it’s time to cut pipe.

* let me first say that if you are a strong devotee of the KOPS deal then you will strongly disagree with what I’m about to share. I personally think that KOPS is as valid as standing over the top tube and seeing how much room between your crotch and the top tube. All one needs to do is look at the two fastest type of bikes out there – the new school time trial bike (knee way in front of the spindle) and a recumbent (knee more than a bit behind the spindle) to realize that this knee-pedal thing is crap.

That said here is a way to get your ball park fore/aft saddle position. Note I’m not talking about reach from saddle to bars. Saddle to bar reach is a separate deal and should not be adjusted by moving the saddle fore/aft. Reach is a function of toptube/stem length.

1) put your bike in a medium easyish gear and ride up a very gentle grade. I use a 42-17 up a slight grade where I can maintain my natural cadence of 85ish without great effort.

2) put your hands on the tops of the bar next to the stem and ride relaxed like this for a bit. Let your body fall into a natural arch and relax.

3) now, with your body relaxed, lift your hands from the bars WITHOUT sitting up or changing the angle of your hips and lower back. Lift just the hands off the bars. Just and inch or so. Do not sit up.

3a) if you can do this without strain or by using a great deal of core strength then your fore/aft saddle position probably isn’t bad and is in the ballpark.

3b) if you have a hard time doing this even after a few tries then it’s a pretty good bet that your fore/aft deal could use adjustment. If you tend to fall forward when your hands are lifted it’s a good bet your saddle could go back. If you tend to fall back then your saddle is way too far back. The latter is pretty rare.

This test, like all tests is not absolute or perfect but I’ve found it to be a good general rule. I think more folks will find themselves falling forward (instead of backward) and need to move the saddle back. Most folks that have had a fitting that is built around KOPS will have a saddle that is too far forward and will put too much pressure on their hands (I’m still not talking about reach here). This will make folks want to fit shorter stems and to raise the bars. This will have the double negative whammy of making the bike handle like shit and make you want an even shorter-higher stem.

By having the feet the right distance in front of your hips your ass and lower back muscles (the best ones you got!) can easily hold your position. You can try this right now in your chair while you should be getting some work done – sitting in your chair put your heels 6″ in front of the chair on the floor. Lean forward a bit. Easy as shit eh? Now move your feet back so the balls of your feet are under the leading edge of the seat and lean forward a bit. It’s takes much more core strength to hold this unnatural position. It’s the same basic deal on the bike. Your feet support you and the added weight on your feet can be put into the pedals. If you pedaled with your hands then having a lot of weight on them would kick ass.

Give it a try. If you decide to make changes make them very small and a little at a time. I little can go a long way.

Time to make the donuts,

Dave

All rounder

Thursday, June 11th, 2009

I just got deep into a lugged all rounder road bike today. Room for 28′s and fenders under long reach calipers and geometry to handle most any road. It’s going to be a fun bike and it’s going together very well.

It’s sunny and warm here so I’m closing shop and getting out on the bike. I suggest you do the same.

Beautifully Brown

Wednesday, June 10th, 2009

I was emailed these photos by a friend of the Frameworks named Noah. The build was a long time in coming but it certainly looks like it was worth the wait. I love the way the different shades of brown and tan work so well together. Nice job on the build Noah.

“It turned out looking great, and the ride is all I could ask for.  I am in love.  Thank you.” – Noah

Thank you Noah.

Imperfect

Friday, June 5th, 2009

This is something I wrote awhile back for a forum and it’s a subject that I’ve been thinking about the past few days and thought I’d take this opportunity to share it here - 

 

It seems to me that the phrase “no two are alike” can be applied to many things we buy and own.

I used to own an old and rare car called a Lotus Cortina and I did a full restoration on it and had it very far apart. When I got into the guts of the car I started seeing more and more hand work. There were grease pen notes and arrows showing where flaws were and subsequent hammer blow marks that fixed the issue. File marks, the slip of a hand drill and the skidding swirl marks it left. Even 40 years after it was made there was evidence of the men that made it all over if you knew what to look for. When it was rebuilt great care was taken to be sure to not clean up or “fix” these things.

I’m sure when it was made those defects that I worked so hard to discover and protect where not something the workers were proud of. They weren’t looking 40 years down the road and thinking how much I would covet the evidence in the metal of the skilled but imperfect men that made the car. They were defects pure and simple. But to me they were a way for me to connect to those men that all those years ago worked hard and long on the car.

I suspect and hope that something similar happens with my work years down the road. Just like the workers at Lotus that made Lotus Cortina #1839 in June of 1965 didn’t want any defects in their car I don’t want any defects in my bikes. I don’t purposely leave my mark anywhere but there’s no doubt that there is a mark and I hope that at some point someone will celebrate it. It’s all part of the charm of something being handmade. That connection is important to me and I suspect to others. So while I don’t think folks celebrate flaws in work they do celebrate the fact that these things are made by living breathing men that are not perfect………… and those flaws are just evidence of that. That to me is something I think everyone can relate to.

French Racing Blue

Monday, June 1st, 2009

I just got this back from JB and wanted to share some photos of it. I have a thing for French Racing Blue (otherwise known as Bugatti Blue) and the first bike I ever made for myself 20 years ago was FRB and I’ve had a number of them since. This is a customer bike and when he asked what color I thought it should be FRB was the first thing that came to me.

I never tire of it.
