    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...

    Recumbent "Off-saddle" aka Bridging Plank: More power to ya!

    Yeah, me too. Works well over what we call locally here " rumble strips" , which are some annoying multiple strips of small speed bumps.

    Recumbent "Off-saddle" aka Bridging Plank: More power to ya!

    Probably this technique has been discussed elsewhere but I thought it would be nice especially for "newish" cruzbike riders to know. I first discovered this technique several years ago while riding my home-made cruzbike clone purely by chance. However later on as I browsed through...

    Cheap Power Meter Anyone?

    As for a cheap power meter, I got a really cheap one that I wrote about here: https://forum.cruzbike.com/threads/affordable-power-meters.14514/post-175070

    S40 newbie questions

    Tip: Seat up when going over bumps or push your shoulders against the seat and lift off your bottom slightly to reduce the jolt from the bump. Asumming that it's only a short section.

    Optimizing Fit - Eliminate Recumbutt/Hot Foot

    Iam sorry I don't have sufficent skills to give a better drawing . I have edited the little drawing on my previous message. The most amount of padding is at the nose of the seat (with the adjustable plate fully extended out) making it look like the Thor Easy seat. It stops me from sliding forward.

    Optimizing Fit - Eliminate Recumbutt/Hot Foot

    Hi @benphyr , Thank you for your interest. Unfortunately I used a mix of black and white pieces of form padding making it difficult to get a good contrast in the picture. What you are looking at is the top of my seat pan with the cushion rolled back . In brief the idea is to make the gluteus...

    Optimizing Fit - Eliminate Recumbutt/Hot Foot

    Thanks @Don1. Unfortunately my home-made roller experiment did not work as intended. The rolling resistance was so bad , I could hardly make a few pedal strokes ! o_O. I abandoned the project. (I think it needs higher precision, bigger diameter rolllers with smoother bearings). My "hot foot"...
