A couple of questions about two models from Dahon
Hello
I went through the Dahon global site looking for faster bikes, and have the following questions:
Dr. Hon
Mu P27
Thank you.
I went through the Dahon global site looking for faster bikes, and have the following questions:
Dr. Hon
- Gear Inches 92"- 304". 304 * 0.079 = 24,016m. Can't be. Is this a typo?
Mu P27
- What are the gear inches?
- SRAM 3 x 9 SPEED DUALDRIVE II (FINGER TAP SHIFTERS): How well does this derailleur + hub thingie work in practice?
Thank you.

Sheldon says the Dr is 32.3 - 94.1".
He says the Mu is about 21 - 120.3"(crank length not given).
Dual Drive systems work well,they just add weight and complicate wheel removal somewhat. You'll have to carry a 15mm wrench for the hub's nuts(no QR) and you'll have to pop off the shifter box. On the plus side you can shift your 'triple' at a complete stop.

Hi.
Dual drive does add a little weight, but its not as much as people often believe.
I looked in to this using the weight weenie site and came to the conclusion it was about half a kilo heavier than a equivalent set up using a front triple.

I'm pretty sure it adds more than that. The rear wheel on my SPTT weighs 3lbs 11oz w/cassette. I'm not going to pull the wheel off my Mu and weigh it(it's a low spoke Kinetix so apples/oranges anyway),but there's def a big difference. A front der and triple aren't going to add that much more weight.

Yes its quite hard to do a direct compairasion. But it is surprising when you add up the weight of a tripple the front mech etc.
