jetstream rebuild...

That's it, the inevitable has happened; it is time to rebuild my old jetstream; 2 years ago, I recommitionned it to start cycling with my daughter and her "tag-along" because I did not mind if it got damaged, it was my old commuting bike which had had a hard life eating salt, mud, curbs etc...
Nowadays, I need a "gravel bike" with aluminium frame that will accept a child seat (not putting that on my carbon frame bike).


while cleaning the frame, I realized that the BB and the rear hub were sized so I decided to keep the frame only... and rebuild using various spares scattered around the garage. I unfortunately needed to buy a few bits:
- rear wheel (I have a spare new front but no rear)
- a BB
- a rear derailleur (I have 2 long cage but not medium )
- rear shock A5 125

Before,


Stripped


Start to look like a bike

Almost finished ... have to wait for the derailleur and handlebar tape deliveries.


I would like to fit a small front luggage rack but it won't be easy; most rack I saw use a top mount usually located on the caliper/fenders mount or V brake mounts but the German A suspension fork is inverted - brake and fender mounts on the rider side rather than the front.

Any clever suggestion which does not cost a lot (surply and topeak look good but very expensive)?

Thanks

I don't know of any solutions to your rack needs (that don't involve getting a different fork) but some of the regulars over at the Touring, Commuting and/or Utility forums might be able to help.

There is little room on the frame but more importantly, I want the rack to be mounted below the suspension like a std rack or fender so that the added weight does not affect the suspension mechanism.

Whether the weight is on the frame or the wheel side of the suspension, the mechanism will be affected. The problem with wheel side is that every little imperfection on the road or steering input will involve shifting the luggage, while the benefit is being able to put the luggage very low to reduce a bikes tendency to topple sideways for example. If the luggage cannot be positioned any lower, and there are no folding issues, the frame bracket would make the better choice.

The bike is almost finished so I gave a test ride. the new shock works well, the gears are nice...
With these bmx tyres, the bike is really easy to bunny hop, good fun.

I found that the dropbar on this bike have a reach 25mm too long so , I will sort this out next week

That looks good. My old Dahon doesn't have the welded bracket either, and feels very back heavy when touring. Putting the weight on the frame rather than the steering works really well too.

Is it an aluminium plate? What are the curved pieces which hold the plate against the frame made of? I have a piece of marine ply that might do the job, especially if I paint it black after sealing.

It's 1/2" aluminum plate. I cut a square of it then drilled a 1 3/4" (44mm) hole in it and cut the remainder into the four pieces that you see. I tapped and screwed the plates together.
