    Three years have passed and the BB ultra still feels as brand new. Really rock solid. Haven’t had any issues with anything so far. The battery needs to be changed at some point soon i guess.
    Coupled BB ultra with a real steering wheel Sparco P310 and couldn’t be happier. Best investment ever made tbh along with the SC2 pro

    Thanks Tomo!

    I added this wheel to my rig for GT cars requiring an open top wheel to see the dash, shift lights, etc. As mentioned in other reviews, the quality is excellent and the feel of all the inputs is very clear and positive.
    I had a small issue with the initial setup and customer service was extremely responsive and helpful. Overall a great product with great people standing behind it. Highly recommend for Simucube and other bases.

    I tried the Asher for a while but I decided to go for the SRB BB Ultra mainly because I’m driving in VR and only iracing. It means that I really need at least one unky switch for the black box.
    I’m astonished about the quality of this product!
    Top material and assembly, i couldn’t be happier of this choice!

    Using two of them for several weeks now.
    Extremely good quality, very happy with the product.
    Like the various options you have with 2 rotary encoders.
    Absolutely on the same level as ascher, own one product of that also.

    SRB BB Ultra batch 3, the build quality is stunning, all inputs are super sharp, good tactile feedback even with racing gloves on.
    The rubber O rings on the rotary and funky switches insure firm grip while rotating them.
    Magnetic shifters are VERY clicky, I’n sticked very thin rubber pads to make them more quiet, a joy to use.
    Simucube 2 wireless connection was instantaneous, no lag, no hurdle to overcome, as plug and play as it could be. 100% signal strength.
    Although I don’t use the stickers (VR user) the two designs of stickers were provided, and looking closely at them, nothing to complain about, print quality is perfect, former issues with red bleed or non filled white areas are issues of the past.
    Mounted the BB with Fanatec 911 GT3 Cup Rim (320mm), perfect fit.
    No adapters needed to mount on the SC2, everything included on SC side as well as SRB is enough (6x70mm adapter provided by SC, nuts and nylstop bolts, everything is in the boxes)
    High quality product, high quality service (delivered to my door in less than 72h when in stock)
    Really happy with the overall experience.
    Thank you

    I’m going to get another one of these because its the best value for the money on the market. So I dont have to switch between rims. I’m adding the second one to the Motamec D shaped wheel. Hopefully I can still get black.


    best money u can buy took only 7 day to arrive super happy

    By far the best deal for a SC wireless option!
    All possible Input used. 2 great 7 Wayx switches. GREAT QUALITY!!!
    I don’t care for the stickers, since I don’t use them for my VR use.

    Build quality and finish
    Electronics soldering job is top notch
    Number of inputs is same as Ascher F28 but 100€ cheaper
    Has two encoders with push instead of just push buttons
    Magnetic shifters are very tactile and have a solid click
    Shifter mounting holes are compatible with Ascher shifter
    Compatible with more steering wheels than the Ascher button plates
    Comes with decals for common functions

    Material of decals is slightly cheap (especially red text on black decals)
    A front plate would’ve been nice
    The anodized aluminum scratched easily when I mounted to my wheel, but that’s not really a con of only this plate, I think rubber spacers would’ve been a good idea (my mistake not to think of this)

    Overall, this is the best value for a Simucube wheel for starting out as all the other options are very expensive. I wish Tomo offered a USB version!
