I got s little time to test the bike outside, and made a few changes: - Cleaned up the cabling to open up the cockpit view. The front brake cable can use some shortening but that'll wait 'til later. - Added some usual accessories for some limestone trail riding: lights, computer, clip-on...

The height seems to be the only difference, so whether you get them or not presumably depends on whether you feel a need to modestly lower your seat or have more flexibility in tilting your seat pan. Ray

Robert, That's great! I was under the mistaken impression that it would take a much longer time due to all the delays in bike supply chains. Thanks very much for the clarification! Ray

After assembling my new Q45 to the standard design and specs (1st photo), I've pursued several changes to make it closer to where I'd like to be when Spring blooms (we expect more snow tomorrow...). Here is the original in-workshop evolution with a list of specific changes I've made, mainly...

I'd very much like to lower my seat a bit on a 2021 Q45. Am looking for one of the short seat brackets. In the attached photo it is the one on the right, about 1 inch high compared to the larger bracket, which is about 1 - 1/2 in high. If you have a short bracket that you're not using and...

That almost looks as complex as a seat post. Ha! Impressive...

That was the approach I was considering but do not have access to welding capability. Without a strong weld, I'd worry about failure of the cross beam through the relatively thin-walled main tube. Seems like a recipe for a stress riser that would be repeatedly worked with a good fraction of...

I think it is fixed now. Holler if not. Thanks Ray

So I decided to cobble up a simple seat post that demonstrates what one can do while waiting for CB to source some new design. I used only readily available parts that require no complex machining , welding, etc. The main tube is Aluminum with a 1-1/8 in diameter and 1/8 in thick wall. A...

That's pretty much what I was thinking for a crude fit check. To avoid too much stress, it would likely require a fishmouth transition on the spacer tubes to match the curvature of the large tube. Even then, this could be chockful of stress risers and may not be strong enough without...

I appreciate what Robert is doing and will be interested in how his new seat post version will work. You know, if you really want a steep recline and don't want to wait for a fix to fit-check a more aggressive seat angle, it looks like you could use a simple straight 1-1/4" tube to replace the...

Rotating the post does not work on this iteration. It looks like the upper part of the seat post has been lengthened from past iterations. As such, when you rotate it, it extends unacceptably close to the rear tire. Without rotating, it moves the attachment point closer to the seat and...

Hi Michael, I happen to have a 650b wheel set with an XD hub and a 10-42 cassette here, so testing on the Q45 is no big deal. My first approach was going to be a 10-42 with a 36 or 38 t chainring. That does limit the high end, but you pick up some by getting the 10t smallest cog. For me...

The Madison-Milwaukee trap (the Glacial Drumlin) is a favorite of local bikers. Generally I prefer the trails that go south or west of Madison - they go deep into the countryside. That's where I'll be testing the Q45 first, of course once we thaw out here! I'm still looking for some parts...

I was looking for a thru-axle adapter to mount my new Q45 on an indoor trainer, and so had to determine the specifications for the thru axles used. As best I can tell, the axles' sizes are: Front (drive): M12 x 1.5; length = 177 mm; 12 mm diameter; 1.5 mm thread Rear: M12 x 1.5; length =...

I was able to get some time this weekend to assemble my new Q45, and thought I'd show the first picture of one here. The build went smoothly following Robert's assembly video for some details. There were no serious hitches, but I did note that several threaded holes (especially for the rear...

Looks like mine is scheduled for next Tuesday. Time to clean up the workshop...

Well, apparently the new Q45's have arrived at Cruzbike and they'll be shipping them out over the next several weeks, per a notice from Maria to all pre-order buyers. So, we'll soon be able to close out this thread speculating on what is coming to new threads discussing the new bikes with...

I've had no problem using a Saris/CycleOps Fluid2 wheel-on trainer with my S30. And yes, you can orient it properly so that the trainer spin direction is correct. Just locate the resistance unit under the front of the bike. It does help to use a road wheel with a 130 mm dropout width so...

Time to replace my old Q559 that I sold last year. Ordered an orange one!
