Default Headset & bar modification

Hi,

I've made a major change to the bike today. Basically I have reversed the headset on the bike and redone all the controls to suit.

The only problem I have run into with this setup is knees and handlebars when pedalling slowly (from stop), they tend to collide... and manuvering the bike is harder because the end of the bars hit my legs - this should be solved by moving the seat back further (which means a new seatpost )

I've also moved the storage bag I had on the bars to the RHS of the bike using the GEBE mount to put it on the bike. I *might* be able to fit another bag on the other side.

My fuel tank is leaking slightly from the top bolt mounting on the RHS of the fuel tank but I cant see a leak anywhere - is there anything I can use to stop it?

Comfortable cruise is now 31mph and the bike will wind out another 4-5mph above that WOT.

Pictures are attached

probably so she can sit more upright and because she can. I like those bars but I would feel a little better if the stem were a smidge more down-where is the min insert on that thing?

Because it saves me back and shoulder ache.. I have tendonitis and a spinal injury so I get pain after about 10-15 minutes riding in my shoulders and upper back.

The headset isnt long enough by a couple of cms - when I pedal I can only do it in a straight line.. but then I am using the bike 100% engine at the moment so its not so much of a problem. I get enough exercise walking and such

Regards how high the thing is - its around the highest extension mark and I have been careful to look at it to make sure it isnt twisting or anything.

It has affected handling - it seems to have made the steering more responsive.. I just wish I could get a longer headset.

Jemma,

I'm in the same boat with the severe back problems, so on my current build used some mid-rise handlebars with a high angle stem. I'd second a higher handlebar approach. Stems are pretty cheap as well and you should be able to find one that will put the handlebar base a little further from your legs but give you a much more upright seating position.

I had to build mine so that I had a completely upright seating position due to my back:


Here are a couple of ideas:
one of these:
KALLOY TRI/MTN QUILL STEM - 1" at JensonUSA.com
With one of these higher rise cruiser bars.. this set has a 126 mm rise.
DIMENSION SUPER WIDE CRUISER HANDLEBAR at JensonUSA.com

What is the rise on your current handlebars?

One other thing.. you could convert to a threadless stem attachment, like this:

DIMENSION QUILL STEM ADAPTOR at JensonUSA.com

That would let you attach any number of different risers, since they are readily available for the threadless style of steer tube:
One of these for example:
Stem Raiser, 1-1/8 Threadless - black

Then you attach a new stem to secure your handlebars:
Alloy Hi-Rise stem, (25.4) 45d x 80mm silver

You could have those bars way up in the air if you wanted.

So far as I can tell they are flat bars - no rise at all. The effect I was going for was the '00's style motorcycle look. Then having put it all back together I find out that its soooo much more comfortable to ride..

Had a guy come chat to me today - im riding a GEBE and hes riding a Moto Guzzi twin of some description.

I might try inverting the bar and see if that improves the clearance thing.
