This way I can make a bike ride just the way I feel it should and not be held back by using stock tubes out of a kit. Reynolds makes special chainstays, seat stays and fork blades for me and I love the way they work. I've had no desire to ask them to make special main tubes for me as the existing offerings in 853 Pro and 953 are just what I'd ask for anyway. I'm fortunate to have worked with the same engineers at Reynolds for nearly 25 years and we have a great relationship and they build what I ask for - pretty cool.

Good enough for me! Very thorough explanation of why you choose to work with Reynolds. Great products indeed. Was just curious... as I start to make a selection on what my next frame material will be.

Thanks again.
Mike

It is interesting to hear you comment regarding how strong the joint is.

In my simplistic mind I have always worried about that style of joint because it seems that the filler would be in shear instead of tension/compression.

I hear you. I recall seeing bikes made this way so long ago before I'd gotten into building and from my then BMX point of view I thought the stays would snap clean off just dropping a curb. But I was wrong. In all the years I've been doing this I've never seen well done side tack fail in normal use. I've seen one fail when it was on a car-top rack and driven into the garage but I don't think of that as 'normal use' despite how often that happens. Strong stuff.

Dave,

Concerning the fork on the stainless bike, are you using a crown that already has some rake to it or is there just such a long and gradual rake on the blades that it looks like they have less rake than a typical road bike?

However you're doing it, I think the subtle curvature looks REALLY nice.

Nope - the crown is straight up and the blade just have a very long duration curve.

I like both but if I feel like showing off some side-tacks are the ticket.

dave
Hi David, Do you think the side-tacks can tolerate the stress of the Terraplane if you were ever to build one? Or do you choose to do fastback because of the aesthetics element? Thanks.

Good question.

The big issue really is simple one - the angle that the Terraplane stays meet the seat lug at are such that making side tacks just fit onto the lug would be really tough. The lug would need to be made to extend much further down the seat tube so that the stays would meet just the lug and not the tube itself seeing as the stays are fairly close to vertical there. It would make for a super long joint which could be strong with all the surface area but the mock-ups I did 10+ years ago showed it looked really awkward.

So fastbacks it is.

Thanks for the question.

Accidents happen - Sometimes the ···· hits the fan and accidents happen and this is what happened recently to an owner of a JK Special I built back in 2012. The fork was bent badly enough that we decided to replace it and the frame was completely undamaged. So just a few days later a new fork was built to the original specs, using the same materials as the first fork and it's now off getting painted as original and the owner will be back on the road soon. Cool to be able to keep them all on the road.

Dave

Onesto.

Onesto.

I started working with Reynolds 953 stainless steel tubing in 2006 when I first introduced the JK Special line of bikes which utilize a custom mix of 953 stainless, 853 Pro, and special non-stainless stays and blades made by Reynolds just for the JK Special…and over the years I’ve been asked countless times if I could make a 100% stainless frameset and up until now the answer has always had to be “no.”

The reason for this was simple – the chainstays, seat stays and fork blades that were available would have allowed me to make a nice looking bike but not one that would ride as I felt it should. As much as I want my bikes to be easy to look at it’s far more important to me that they ride right first with looking good being an added bonus.

With this in mind I was very pleased to have been asked by Reynolds last year for my input on new 953 stainless stays and blades and just this spring the new parts have become available. Now, for the first time, I can offer a fully stainless steel bike that has a great raw and honest stainless look and an even better ride. I’m pleased to announce a very limited run of five lugged stainless bikes that I’m calling Onesto. The pricing for these five frame and fork sets is $4250 and they can be purchased as a fully built ready-to-ride bike or as a frameset. The framesets will have polished logos and a bright and frosty glass bead finish as shown.

I’m really looking forward to building more editions of the Onesto and finally being able to show off the much fussed over metalwork that many have told me they’d like to see. I often share photos of my non-stainless bikes before paint and a common request is to leave it raw so as to show off the metal work…unfortunately with steel this doesn’t work out as we’d like it to. But with stainless I can build the frame and finish it without any paint at all and really show off the hand worked lugs and details. The end result is an honest bike with the ride of the JK Special and the look of raw stainless. As a craftsman I’m excited to now be able to show off a bit and finally give people what they have been asking for.

If you have any questions about the Onesto please contact me and I’ll get you answers right away.

Thanks for looking -

dave

That looks classy. Might have to get in line for one when the Terraplane stays become an option.

Working on this - should know one way of the other in a few weeks at the most.

Thanks!

AWESOME work, Dave! Gorgeous. I'm a huge fan of the acciaio inossidabile, if you recall I was one of the people prodding why you didn't have one available, though I totally understood your reasoning. What sizes did you make in this run? I'm knee-deep building up a speedvagen at the moment... but I'm super interested in this new product of yours.

Cheers
Mike

Hey Mike -

Thanks for the comment.

I think I may have given the wrong impression - I will be making a run of five and all will be sized to the owner.....none will be 'stock' sizing and all will be custom so if you wanted one it would be built for you.

Yep, I totally misunderstood, sorry. I thought you'd already made five in various stock sizes like a "validation lot", as we'd say in my industry. I'll be looking out for your additional info on the seat stays, certainly something that sets your frames apart.

Cheers
Mike
