    Ventisit 2cm or 3cm?

    I am pretty sure all of our Dentists are the 3cm ones. I am not sure that Bart at Dentist has done a 2cm one for us, actually. maybe a long time ago...

    rear rack wobble

    The movement of a load can be exacerbated by the amount of movement of the rear suspension up and down in general. Have you tried to pre-load the stock spring collar a good 6-7 turns to stiffen that up - that can help. Also when carrying that much weight you might need to up the shock to...

    Convert Q45 to ebike

    A front through axle motor hub is the holy grail but sadly there are basically none. Literally. There are no manufacturers really making them. At the Taipei Cycle Show this last spring we saw ONE manufacturer that had designed a VERY COOL front hub that rose insanely smooth and was all...

    Swap to 26" MTB Wheels on Q45?

    The hubs would have to match - if they are 12mm through axle and the same width - 100 rear and 142 front.

    New Cruzbike rider issues

    This is exactly how I have adjusted my own dentist pads on various bikes to customize the fit and support where needed like at the lip or for lumbar, etc.

    Tubes or tubeless

    If you practice taking the wheel off and putting it back on about 20 times in the comfort of your own home I near guarantee you will get the hang of it and that it will never be an issue.

    Airtag Mount for S40

    They have sticky pads that are designed to go on the inside of suitcases: https://a.co/d/0UTCgGu Put one of those on the back of the seat (nice smooth surface to stick to) so the tag is fitting inside one of the frame holes.

    QX100 derailleur hanger: which type?

    The QX100 has a standard type of DR hanger. We have those in stock, but also it is a hanger that many shops can access even though they may not have one on hand. There are a zillion "stock hangers" out there. The QX100 uses basically a Wheels Manufacturing "Hanger 25" like this one...

    Q45 with 24" wheels?

    Possibly - it would take some decent amount of disassembly I think.

    Q45 upgrade complete

    That is one sweet ride.

    Q45 with 24" wheels?

    A 24" Q is a sweet machine. I don't have any pictures, but can say that you might lose a bit of that "rolling speed" of the larger wheel, but the bike is more nimble and handles low speed really really well - better than the larger wheels even so for urban city riding it is a bonus. One of my...

    QX100 headset: alternative to FIRST BI-3

    Those seat tube clamps won't be the right size to properly clamp a steer tube, unfortuntely.

    QX100 headset: alternative to FIRST BI-3

    Hmmm. It is basically the same thing, just "ungraded OEM" so not an item that is available to consumers as it is only provided to manufacturing sector. The Problem Solvers as a "Brand" is a QBP (Quality Bike Parts) named/branded line for them as a distributor. It is probably made by the same...

    QX100 headset: alternative to FIRST BI-3

    That should indeed work in combination with a regular headset. It is pretty much the same combo that is now used on the current T50. Though that iOS an OEM version and not the Problem Solvers brand. Robert

    Florida bike Safari 2025

    I'll (NOT) be there. Sorry all I confused this thread with the RAGBRI one.

    Q45 Under seat water bottle cages

    The mounts there are really leftover from the older days when the bike had an entirely different seat, and the newer style does get in the way, unfortunately. I have seen a few of these position adjusters used to effectively "lower" the cages to a better position, though I can not speak to how...

    Very interesting differences between Vendetta 1.5 and V20

    That would be about right. 2013 or 2014 (depending on when manufactured - having "model years" is problematic especially back in the earlier days. The manufacturing cycles do not necessarily lend easily for "made in _____ year" all the time.)

    Cheap trainer setup for proper fit

    On any trainer through axle or QR - you will want to use the stock one that we provide with the bike. Most of the stock off the shel QR's ad through axles that come with trainers will be too short as they are designed for upright bikes - where ours are longer as we have to account for the wider...

    Q45 - SNOW DAY!

    That bag is a NEW addition - and they are on the way via ocean freight. Hopefully by mid-end of April. The one in the video was an early finished one just for the filming. Stay tuned! It is an award winning trunk bag that can fit a MacBook laptop and has some small fold-down panniers and an...
