After a short waiting here we are with the prototype, beautiful and functional as always! 🙂
Assembled right away and checked that all the functionalities work as planned, we are happy to announce that soon these beautiful, light and innovative lever will be available for everybody!
And so, also the Brake Lever gets the V2 declination… As for the Shifter lever, also the brake lever was (is) working well (still on my bike) but for the same reasons (see the post about the Shifter lever) we went for CNC…
Prototype purchased, aluminium 6061, black glossy anodized, can’t wait to see how it will be!
As usual these are something completely new and unseen:
All parts are CNC machined;
No welding: all the parts can be replaced singularly;
The brake lever can be adjusted in height (about ±15mm), something that cannot be done with the OEM lever; and can also be adjusted in length (about ±10mm); our unique and unseen (if you see others with the same system you can be sure it is a copy …) allows a quick adjustment to make it suite your needs.
For time being enjoy the CAD, soon we will show you the real one!
And here we are, with the Shifter Lever V2! The V1 was working well, but…
We made as it was (steel, different parts, partially 3D printed) following several suggestions and our proper inspiration, but it turned out to be expensive and too time-consuming. In addition, the second prototype shows some defects: of all places in the 3d printed steel base! although it works well we could not stand that defect, and the producer could not guarantee, at the same price, that the future parts would be flawless…
So we went for CNC machining!
Models modified, purchased, and here we are, this is the first prototype of the V2!
Less parts even if the shape is the same (still possible to make it in three parts, as the V1, we will look for the best option!), no paint needed, completely in aluminium 6061, still adjustable and less protruding like the V1, still with the tip at an angle so it will fold easily, and probably it will be possible to get them anodized…
Now time for the brake lever, that one also will be changed and made in aluminium, soon a prototype will arrive!
Now the winter is coming, so there wont be so much testing (even if we are confident that it works) and we have other projects ongoing (first of all the Tower), but as always if there was enough real interest we could organize a buying group.
Here we are, ready to show off our next project, the Giamaicaworx Tower, at a more or less final design stage…
There are still a few details to be worked out, but we are going to make the first plastic prototypes to verify envelope and interfaces, and check the feasibility for what concerns the assembly.
Made as a mix of parts in carbon fiber (the main plates and some secondary plates), aluminium (the windshield plates and other plates requiring bending) and 3D printed plastic parts (covers) everything is designed to keep the assembly light and stiff, and of course… beautiful!
And, as usual with our parts, it will have some features that nobody else offers:
Weight: still in definition, but we are at around 1.1kg (from CAD); the OEM parts (the two main parts) weight alone 710g, then comes the X cover, the dashboard cover, the GPS bar and screws and washers etc etc, we are pretty sure that we are at the same level, most likely overall a few grams lighter;
Extra attachment points: we added two extra points without having to modify the frame (not shown yet, because we have to take final measurements) that help the OEM attachments, which in a few cases failed because of the extra weight added by aftermarket towers or other optionals;
Adjustments: the position of the dashboard can be adjusted in two positions, to suite different preferences or to move the dash when using pads or other large screen or roadbooks;
Quick release: the windscreen (same position as the OEM one) is attached by 4 of our Quick Release, modified to fit the new brackets;
Compatibility: of course it is compatible with our Front Rack and Device Holder; the Front Rack will only require a cut, to remove the no longer needed attachments to the OEM 12mm bars, while the Device Holder will fit without any change.
New Add-On: a new Device Holder is coming, bigger and more robust, but here we need your help: we don’t use devices as tablets or roadbooks, so we don’t have the interfaces; we will design the new part with standard AMPS hole pattern and few extra holes, but if you provide other interfaces (holes positions and diameters for you device) we will be happy to implement them.
Costs: Last, but not least: money! We don’t have the total costs yet, but we can foresee costs that will surprise you (in a positive way), as soon as we have them we will post them!
So, now it is time to order/make the plastic parts! See you soon!

The levers have been used now for more or less 1500 km, mostly on the road, but have seen also some (light) off and they work well also when standing.
The shifter lever has an adjustable (and of course foldable) tip, it can be moved ±10mm back and forward.
The brake lever has an adjustable part, the one where the tip (OEM or another compatible) is attached to, that can be moved ±10mm back and forward as well. And the whole lever can be adjusted in height (at the tip) of about ±15mm.
The grey parts in the pictures are in stainless steel, 3D printed, it looks like they don’t rust, so no need to paint them (they have also seen some salty water).
The levers (in black) are in carbon steel, they have been painted (powder coated) but we have a spare one, and does not show rust, even if it has been over two months in my (not isolated) garage, subject to humidity. Anyway we think it is a good idea to paint it.
We have received some requests for different colors, but we can only paint in black, for a simple reason: it is the only color I have/use with my hobby powder coating equipment. By the way, the quality of the paint is good, but do not expect professional paint quality. If you want to paint them in another color you will have to do that yourself.
No welding: all the parts can be replaced singularly.
The lever tips are adjustable, about ±10mm back and forward, from a position “more or less” equal to the OEM one; the shifter lever tip is also angled few degrees, so that it should “close” more easily in a drop; the brake lever can be adjusted also in height, about ±15mm, again from a position “more or less” equal to the OEM one.
There is a last ting to mention. The levers use a bushing different from the one in the OEM levers, same ID and length, but different OD. So we needed new O-rings. When we got them we noticed that, together with the tolerances we get on the parts, they play a huge role in the play the levers got on the pivot bolt and the friction when the levers are moving. They can actually, if too big, lock the lever, or make it hard to move. So we played a bit with o-ring dimensions, and we came to the conclusions that you can actually play with the o-rings and get the best combo play/friction according to your taste.
We used two thinner o-rings (which will be part of the kit), which made the levers very light to move but gave more play (movement) around the pivot bolt, and we have also used a thinner o-ring, at the interface with the washer, and a OEM one at the interface with the head of the pivot bolt, this giving less play but more friction.
In both cases the levers work totally fine.
See the two videos we posted on youtube, showing the play in these to cases (for the shifter lever, same happens on the brake lever):
Following a comment for one of the Rear Rack owners, we decided to test an additional spacer, between the tail and the Rear Rack, similar to the one used with the standard Rear Rack.
Actually it is not necessary, as the Rear Rack HD uses 4 screws, so it is stable as it is. But the additional spacer increase the stability of the Rear Rack, making negligible the (unavoidable) already small deflection when loaded.
The spacer also provides an additional attachment point (personally I have used to secure a small tool bag positioned under the rack).
It needs a conical washer and a countersunk M8x80, but a standard M8x75 with standard washer works as well.
The spacer is available for free on Thingiverse (search our name, the spacer is named FGWX-0-B-003).
Eventually… also the latest group buy is completed!
All packages are on their way, most of them already arrived, the last ones will arrive soon.
There has been a delay, caused by an error in the parts…
Shortly, the Quick Release has a left bracket and a right bracket… we got all left!
Even if the QR would have worked anyway, we didn’t want to deliver them that way, so we got in touch with the producer and they started the production of new parts right away, and even if they manage to produce and send them very quickly it cause a one week delay.
In the meantime we packed all the remaining parts and sent first all the packages that did not have QR in it, trying to minimize the delay.
Lesson learned: having a left and right bracket wasn’t really necessary, so the QR design has been modified, so that now the same bracket is used both side. 🙂
From today is Giamaicaworx also on Thingiverse! Searching our name you will find several parts (more to come) that can be downloaded for free and 3D printed.
we made a correction to the PETG parts of our Handles, you can now download it from Thingiverse
just made a small clip to carry out Carbonfiber Shifter Rod (or the OEM one) under the seat, another Giamaicaworx effort to use all the available space on the bike! 🙂
Do you want to mount our Siderack closer to the bike? Or do you need spacer to experiment with the position of our parts? We made a large database of spacers, both for M6 and M8 screws, feel free to download them!
As promised/anticipated, new versions of our beautiful and practical Rear Rack and Side Rack are coming, the prototypes are on the way, but they won’t be fully tested until spring 2024.
The Rear Rack HD is actually our known “old” rack, but a couple of reinforcements, made in 5mm aluminium and bolted to the Rear Rack, will make it capable more weight, and integrates also the handles. The reinforcements are also designed so that the rack plane is about 25mm higher, allowing to store a small bag with tools or a tire repair kit underneath. And still the Rear Rack can be used without reinforcements, giving plenty of possibilities and configurations.
Same for the Side Rack, it is our well known design, but now made in 5mm aluminium, and with a slightly increased surface, so that larger saddlebags can be used without problems. Weight capacity is increased as well, due to the increased thickness and to the third attachment point, the M8 screws used by the OEM luggage systems.
