Hey Yan. Thanks for responding. I've been drooling over your bikes for years and finally was able to get a bare 9 front suspension. I was also able to get a hold of a Saso shock fork but until I'm ready for that, I figured it'd be nice to ride it around first...since the shock is threadless, I thought I should go threadless with the rigid fork as well. I'm just not sure of the headset to use. Will there be enough clearance for a 1 1/8" threadless headset? What would you recommend?
Also the bottom bracket that came along with this doesn't fit. Do you have the specs for that too? Thanks in advance!
- CJ

CJ,

Apologies for the delay. Classes ended and finals started last week.

FYI we have had 4 different front suspension frames over the years. I assume you have the newest model? We have always used 1 1/8" headset ( it was threaded from 2005-2009 ). FYI parts may be very expensive, I understand nice 20" wheels are hard to come by. Make sure you spend less for parts than our $549 retail.

Om,
Yan

Anyhow good weekend

back to the Downtubes thread ...lol

Thor, Brakemeister, I have been away from the forum for a bit, I am so sorry to hear of this. You have never hidden who or what you are, and you have been a great servant of the folding bike community. The forum would be diminished without you.

hi anyone including Dr Yan, will this be ok as a replacement for my DT Mini seatpost?

I can't do the measurements of the seatpost I have. The bike itself is umm, the subject of a custody battle in my rather painful divorce, but I think I will get it in return for the bulk of the equity in my home. That was.

We stopped selling the mini's in 2009, and will introduce them this summer. I recall the old ones used a 30.4mm seatppost but I also think the early mini's used 27.2mm seatpost.

Does this help?

Yan

Yan thanks. I think I must wait until my green baby is back in my arms. I think it is going to work, but let's see

I am greatly pleased to hear the mini will be back. I miss it a lot as my everyday folding workhorse. I have a Brompton SL2-X, which is lovely, but almost too precious to ride in the city I live in, which is stupid. Plus the mini has more gears. Hope you will do it in green. FWIW some simple mods to enable holding it together when folded (magnets ? good bungee mounts ?) would give it a big 'in' on the commuter market in the UK.

Abs, as my Brazilian friends sign off..

For the Sculpture Race I also built noise makers
(got the idea from the Dremel site)



It will need mods to tune it lower. Right now it is more of a clack-clack

Those noise makers should be standard equipment for urban commuting.

Riding to the race start, my partner was not comfortable riding amongst the traffic in the city, but I would let her lead the way and she knew I was nearby (and not stuck at the light or whatever). And during the race (more of a parade), I would lead and slower bikers and pedestrians would slide out of our way. Clack-clack-clack-clack-clack-clack-clack-clack-clack-clack-clack-clack-clack.

Now if we could put these things on the Prius, I would not worry about getting hit by one of those silent killers.

I think my factory assembly is top notch. Many customers tell me they just take the bike out of the box and ride. The percentage is increasing every year.
Are the Novas and the 9 Speeds made by the same factory? While both are very nice, they seem to have different (fabrication) styles to me.

Monti- all our bikes are made in the same factory. The Nova's are not at the same level as the 9 and 9FS, however they are great for the price.

marxmini- my wife runs distribution in Indonesia. We are looking to expand to other countries ( we are offering incentives ).

Thanks,
Yan

Anyone know of any suitable replacement for the suspension pivot of a 8fs model?

I ask because I've noticed a bit of flex on the lower part of the bike and it seems the pivot is the cause of it, makes a creaking noise if I apply more force to one side of the pedals.

I don't know if it is the same set up as the 8FS, but a while back someone made changes to the Downtube Mini's suspension design, including mods at the pivot. Here's the link:

Couldn't see anything about the pivot itself, only saw him adding a piece of rubber to the spring section.


8FS suspension springs are beefier so I don't really have a problem there.


This is the area that I'm referring to.
