If it has 89mm clearance with 175s then you can ride it with 175s. If it has only 90 mm clearance with 165s then you can't ride it with 175s. You don't measure a frame, you measure a complete bike. Legal with 165 mm cranks and not legal with 175s is possible. One might question the sanity of some of the UCI rules, and of course they don't apply to non-racers, but thems the rules none the less. So if you spring for a custom bike with the intent to race it, and are not allowed to race, you might reasonably want your money back. Assuming, of course, the builder knew your intent and crank size. A little while ago I measured my 62 cm Eddy Merckx Corsa Extra - I have less than an 1/8th inch clearance with 23 mm tires. That means that I would hit with 25mm's. Not that I would pay any attention to that because of the way I ride but that is so near an overlap that the commonly used 25 mm tires today would strike. |

It does not have to be a $xxxxx per seat CAD package. My engineering drawings are done on a CAD that cost me just under $1k and can also do layout, even automatic routing of circuit traces. I only use it for schematics and that part is the full unlimited version. Autorouting invariably stinks. They have give-away packages from companies now that do auto-routing. Not ONE of them matches a good layout man. Most generate so much noise in the routing that you have your uC making mistakes in low power high speed applications. |

Not ONE of them matches a good layout man. Most generate so much noise in the routing that you have your uC making mistakes in low power high speed applications. I always farm out layouts, then allow the layouter to auto-route digital stuff and mundane analog but not any hot stuff. He uses a well-seasoned version of PADS and the auto-router is quite good. I haven't yet tried the auto-router on my Eagle V7. -- Regards, Joerg http://www.analogconsultants.com/ |
