Hi Marc, The SRAM X-Gen front derailleur works very well, but they're getting hard to find - here's a listing: http://www.beyondbikes.com/bb/itemdesc.asp?ic=QFD4601 You'll need a 34.9mm clamp. I think they start at 34.9 and use shims to fit to smaller tubes. They're being phased-out so the...

Yea, verily! Ward, I think Mark's experience should be very helpful to you because Mark came from a very similar "platform" to yours. He's chronicled his experience and progress here very completely and has been a help in some of the development that happens in the background in Cruzbike Land...

Marc, Ahh, yes, I have one of those - Sugino double 110mm off of an '80s or early '90s Schwinn LeTour. Wonderful straight crank arms and small Q factor. That sits wayyy down on the taper, and I think with the 125mm axle you'll be golden. I put mine on my SR proto with the 122mm BB axle and...

Hi TD2, What lead you to select a 125mm BB? I'm thinking you'll run up against a chainline issue (shifting into the top ring might be noisy and difficult). The Freerider uses a 122mm for its single chainring, the Sofrider V2 uses a 113mm for its double... Or does your road crankset sit...

Hi Huw, Having just watched this: http://www.northroadbicycle.com/fframemovie.html I love those '60's style promo films... I think you'll have a very entertaining and unique bike with excellent riding qualities. And there's a good chance it will be able to break down like the original for...

As Mark would say, Pictures, man, pictures!

Got that right... You're as bad a tinkerer as I am. If you had other hobbies, go ahead and sell the stuff now... Have Fun!

Hi John, Lemme ask you... Do you have enough leg clearance to lower the bars a little? In other words, can you shorten the TFT distance between the bars and the pivot clamp? I have learned that the entire arm is a system, and having the elbows bent can transfer stresses to the wrists. Your...

A great deal of Cruzbike development has focused on transfer of power through the steering assembly. This power transfer is what sets MBB apart from other designs. The front triangle of the Silvio, Sofrider and Freerider are exceptionally-rigid assemblies. This is carried-over as much as...

Hating to say this... The cap screws on the bottom of the fork legs will interfere with the triangle brackets. The disc caliper mounts on the offside leg are likely to interfere with the cassette/freewheel cogs when the fork is rotated 180 degrees. Doug

Amazing what you can learn from a camera angle! Good Luck!

Hi Marc, and welcome... This is probably a good bike to "get a taste" with... A few things based on the picture: 1. I'm assuming it has a square-taper bottom bracket; I've noticed that sometimes down there in wally world bikeland that the specs change around but the pictures don't - I'd...

It's hidden between the pictures... 53/39 170mm crank with 13/29 cassette.

Hi, I built that bike. It has 700c Campy Vento wheels and 700x23c Conti GP4000 tires. It uses a 53/39 Centaur crank and a Centaur 13/29 cassette. At the time it was assembled, we didn't have a provision for using triple cranks for any but the tallest riders. Now we do. Its sister bike...

They're set in red Loctite, so I think they'll stay put for the short term... I'll use this one long enough to shake out the details and then make another one, maybe even a pretty one. I need to relieve the lower section of the adapter to let the QR run out to the end of the dropout, too...

Almost done, just gotta get a long rear brake cable...

Jack's done a lot of research around seat recline... I'm about to alter my Sofrider seat mount to duplicate teh Silvio operating angles... means raising the front of the seat pan a tad...

I would reiterate Mark's idea of prototyping this in steel, which is much more forgiving, before potenitally destroying the aluminum frame. A couple of things that have stopped me from working in aluminum and CF: 1. Welding aluminum puts all kinds of interesting stresses in the tubes, and the...

A most excellent truckster! Add a pair of footpegs to the false bottom bracket in the swing arm and you could be runnin' a taxi service! ;) Nice job.

Nice looking ride, I like it! :D As Mark suggests, the dynamics of the bike favor having the seat close to the steerer, and that will automatically relieve your seat angle. You can also turn the seat post clamp around backwards and get a few more degrees incline. Mostly, ride ride ride...
