    mid foot shoe adapter - has anyone tried this?

    I honestly don't know why shoe manufactures just don't offer extra holes near the midfoot section. It shouldn't be so expensive to move cleats further back. Personally, I just drill my shoes and bolt the cleats where I want them. Works for SPD two-bolt cleats ( 3-bolt road cleats present a...

    weight saving

    This is true upto a certian point. Once your body weight drops to the sub 70Kg (~150 pounds) range, the weight of the bicycle as percentage of your body becomes significant. The power to weight ratio becomes a major factor. When I look at professional bicycle races the lower UCI limit for...

    Gearing Question on Stock S40

    Pretty good actually. I could not tell the difference. It just felt as stiff as my old Shimano one. However, the catch is that the BB spaces and the bearing preload washes were plastic. They became brittle and cracked when I was swapping the two cranks between my bikes. Good thing is that the...

    Gearing Question on Stock S40

    @Always-Learnin , on my 2019 S40 I have used a 48T with a 11-46 Sunrace(CSMX8 11-46) cassette. I added two links to my chain. (Using a second quick link) I do notice the gear jumps but I've gotten used to it and my cadence range has adapted. Occasionally I still spin-out at around 59-60Kph...

    Yes, we got some pretty amazing people here. I don't deserve such generosity. I wish I could be able to do the same for someone and give back to the community too. God bless you all.

    Looking for a S40/Q45/V20 Straight Boom Slider

    Thanks. All they have to do is to ship to Texas where our Cargo company is. I guess that should be about $20 locally. I can pm the Texas address details to whoever has the slider From Texas to Kenya the cost will be invoiced to me by the cargo company on arrival. . A brand new slider is...

    Hello out there, if anyone recently upgraded to a curved slider and may be having the original Straight Slider that they don't need, kindly inbox me. It will be local USA shipping to Texas. I estimate that to be about $20, I'd like to replace one on my S40 which developed a crack at the...

    Boom Cracked at Handlebar clamp While Climbing

    After this incident, I couldn't help but think if it was possible to redesign the end of the boom to make the handlebar clamp area a replaceable zero offset Oversized stem that screws in or clamps to the end. It might add some few extra grams but it make is easier and cheaper to replace. It will...

    Boom Cracked at Handlebar clamp While Climbing

    Thanks. I will religate it to the trainer for now. (I got a used Cycleops fluid2 that works well for my S40.) I think it's safe enough indoors on a stationary trainer in this case. No risk of crashing incase the handlebar comes loose. For the outdoors, I will go back to my homemade MBB for...

    Boom Cracked at Handlebar clamp While Climbing

    My only fear is that welding aluminium is a lot more delicate than steel. If not done properly it can result in an even weaker joint on an already high stress area. I think it needs TIG or MIG which have don't have access to at the moment. I also read that 7xxx grade series aluminium alloys...

    Boom Cracked at Handlebar clamp While Climbing

    Today, while I was climbing a hill on my S40, I heard a rhythmic clicking sound in sync with my left foot. I thought it was my wheel. Stopped and checked and wheel was fine. Spokes , derailluer, brake all was clear. I hopped back on and the sound momentarily disappeared but came back when I put...

    Cruzbike S40 in Nairobi, Kenya!

    Thanks! The S40 is quite a capable bike once you dial-in the fit. It can climb well (especially short punchy grades) once you train on and fully adapt to it. It takes time and patience. The upright aka DF bikes are still faster uphill particularly on long arduous grades. To be fair, however...

    Cruzbike S40 in Nairobi, Kenya!

    Thanks! Incase anyone is interested in a rim brake option for a 2019-S40 front fork, that is a Tektro R539 caliper brake. I think they are Long Drop Brake Calipers 57mm (The rim brake pads can be adjusted between 47 and 59mm , I think. I will need to confirm.) They work well. My original...
