    Ouch

    Glad you are O.K. and I hope you will get a replacement of all that was damaged soon. I think all FWD MBB bicyles have more weight in front when the rider is seated on it than at the rear. I usually inflate my front tyre higher than my rear. Mine are 700x28mm schwalbe marathron at the front...

    MBB on a diet (9 kilograms)

    Priceless! @LarryOz, I wonder how it feels to climb a 15-20% grade with a seat reclined at 20deg and with the BB at 8 inches above the lowest part of your seat. I believe you encountered those at RAAM. I know human beings can adapt to most situations, but how long did it take for you to adapt...

    MBB on a diet (9 kilograms)

    Maybe I should have said skilled at racing with tact. There is one video they do a "sandwich" move to drop a DF rider. In one of the videos above Serafino performs a formula 1 kind of move on the bicycle riding in on the inner side of a corner to hold his line in the mini peleton.

    MBB on a diet (9 kilograms)

    I guess if it was to be produced it would need Large, medium and Small frame sizes. Nothing is perfect, I guess, there are always pros and cons to every design. He explained that the low bottom bracket is good for better blood circulation to the legs and I guess for a more natural orientation...

    MBB on a diet (9 kilograms)

    Marco 's design has four main advantages/improvements for a general purpose road racing bike: Completely nonadjustable rigid front triangle means max power transfer and easy wheel change. A telescoping adjustable handlebar mount adjusts to rider without changing the front triangle back and...

    MBB on a diet (9 kilograms)

    If you practice at 32° or 33° long enough you will adapt and eventually gain some good control. But you might need to add a headrest, I think.

    MBB on a diet (9 kilograms)

    My favourite part is at about 9:25 : Serafino and Marco team work to split the group! Then at 10:19 the DF leader looks back and realises they are only two left against two recumbents and the rest have been dropped! Wow! Marco, what is the weight of Serafino's bike? Why does he not use Rev...

    Getting Off the Fence

    Looks like the front wheel blowout cursed the bike to pull a partial stoppie, and the rear wheel lost traction. It's, after all, a front wheel drive and it puts a lot of stress on the front wheel. Your front wheel should be as bullet proof as you can make it. Not just the tyres but the rim...

    S40- Wow!

    Same for me. I ride 700x28mm Schwalbe Marathon HS420 performance in front at 85 PSI and a 28mm Schwalbe Delta Cruiser reflex at the back at 65 - 70 PSI (It can allow as low as 55 PSI according to the manufacturer spec on the tyre). I weigh an average about 69 Kg (151 pounds). This is a good...

    Getting Off the Fence

    I'am trying to understand the incident. Do you mean the rear wheel literally came off from the and the rear dropouts touched the ground? Did the skewers break?

    S40- Wow!

    Looks like you went back to 28mm or sleek 32mm tyres! You really must be getting a hang of it now!

    Happy New Year 2018!

    .. for me I'am more scared riding my recumbent on extremely congested roads like these because quick starts and stops are harder for me on my recumbent than on the DF. I also feel psychologically more vulnerable because I'am seated lower and with slightly wider handlebars and I cannot jump the...

    Happy New Year 2018!

    The wide lens of the action camera makes it look worse than it really is. However, I still choose my routes to avoid highly congested roads. Being a weekend it was alot better. On a week day, it's absolutely crazy. I can only dare ride it with an upright for my commute. Here is an old video on...

    Happy New Year 2018!

    Yes, considering the weight of these bikes, the triples are a must for steep or long hills. However, unless the grade is greater than 4 - 5% or very long, we rarely use the granny gear. (My cassette is an 8-speed Sunrace 11-34 and my crankset is a 50-39-30 Shimano Sora. I use barend ratcheted...

    Happy New Year 2018!

    Great observation! Yes, he cut off the old BB from the original U shaped ladies donor bike and MIG welded the frame back together. Mine was a suspended Y-frame "step through" ladies bike. I just welded a seat stay and removed the suspension. Generally, step through cromoly/steel ladies bikes are...

    Happy New Year 2018!

    We both have steel framed DIY MBB bikes modified from old bicycles. Quite heavy and not for the faint hearted! :p. Mine weighs 18Kg yet it is noticeably lighter than his! I guess his is more than 20Kg! Funny thing is that he climbs better than me despite the extra weight! We could both make...

    MBB on a diet (9 kilograms)

    Just curious, what seat recline angle have you set on it? Looks like 40 degrees or about 35.
