TIres for English Century

Just finished a brutal trainning session (60 English miles of flat highway) with my Dahon S1.
Had added a drop handelbar with foam...but still need to fine tune the Reach.

It was pretty comfortable (like Cadillac) ride...with the 1.5" Kwest tires, 45 psi.

I was only averaging 10 mph with the 62 gear-inches gearing...so I probably need to increases GI and reduce tire friction...

Looking for faster tires...any ideas?


Probably going down to 13t cog to incrase GI to 68...after a few more brutal training sessions, when my legs get stronger

Maybe you can find Primo Comet Slick tires or Schwalbe Kojak.






Over Months I averaged less than 10 Mph , on a bike tour..

doing 100, start real early.. get most of the miles covered before lunch.

Have done the 100 mile route of the New York City Century on my folder. Was using
Schwalbe Kojaks(folding) for training rides and actual event. Primo Comets roll pretty fast as well.

13 tooth sprocket might be hard to find to fit.

You are tough----60 miles on a single speed is brutal....

100 miles on that bike would wipe me out---

Luckily, the route is completely flat.

Without hesitation, if I were picking a fast tire for a relatively flat and long road coarse, I'd use Greenspeed Scorchers without kevlar (406). Unless the coarse was really smooth, I wouldn't bother increasing PSI since the relationship between rolling resistance and pressure on "real" roads is u-shaped.

If you want to experiment more there are some super high end BMX tires that are supposed to be exceptionally supple.

Okay...I am finding good tire is very expensive.

I find Primo Comet Recumbent for $20 less than the regular Comet.

Can I use a Recumbent tire for my Dahon Boardwalk?

What is different between regular tire and recumbent tire?

Is Comet Recumbent just as fast rolling as regular Comet?

Only thing I can think of is that recumbent bikes are usually heavier...maybe thre tires are beefier as a result. (Since I'm trying to find a light weight tire with low rolling resistence) Also, recumbent bikes don't lean like regular bikes...design might be impacted.

$23.78..."The Primo Comet Recumbent is a fast rolling, high pressure tire."

$38.49..."
The Primo Comet Kevlar is a fast rolling, high pressure tire with a reflective stripe on the sidewall."

The Kevlar version has a Kevlar anti-puncture belt and reflective side stripe which make it more expensive. Otherwise they are identical. I bought a pair of the plain ones last month. The recumbent is just a term so people with recumbents will find them. They are not recumbent specific.

Spec says...
The Kevlar version ($38.49) is 42 grams lighter than the recumbent version ($23.78).

Is 42 grams worth $15 more?

Recumbent -- 342 gram
Kevlar -- 300 gram

That seems wrong. I've used both versions and it is the same product except for those mentioned differences. My plain version is 265g. Just weighed it, bought actually from them couple of months ago.

Mine are 451mm though.

Your 451 tires are narrower...so lighter.

451-iso 1-3/8"-wide, plain > 258 grams
451-iso 1-3/8"-wide, kevlar > unknown grams

406-iso 1.5"-wide, plain > 342 grams
406-iso 1.5"-wide, kevlar > 300 grams

406-iso 1.35"-wide, plain > 280 grams
406-iso 1.35"-wide, kevlar > 294 grams



I'm starting to see why 451 is so attractive for speed'sters.

I have been reading alot of problems with the Comet getting flat tire.
Now I'm scared. I guess light weight comes at a price. You cannot have your cake and eat it too.

My Kwest never gave me any flat. The Kwest came with the bike. I have no idea how puncture resistance Kwest is. It's 406-iso 1.5 with 60psi-max. I read Kwest is a cheap tire. The side wall is very soft.

I'm scared the Comet will mean I have to fixed alot of flats on the side of the road.
I don't mind wrenching...but since this is a single-speed bike, removing the wheel to fix a flat means getting my hand greasy. It would mean having to carry towels to clean the grease off my hands.

I have had no problems with punctures - not zero punctures, but very very few. I tried all sorts of other brands and types... Comets are in my experience way better than others for road riding. Tough, durable, light, fast. Comets are the unsung hero of tyres. I just lament the difficulty in getting these at reasonable prices.

Kojak? Tried them, fragile. Kwest is quite good too, another unsung hero, but I like Comets better as they are tougher and lighter.

Kojak sidewalls, you mean...

You mean the sidewalls are not the toughest, that's true. Do Comets not also have fragile sidewalls? I used folding Kojaks in off-road situations a few times, and the sidewalls did get scuffed up, but i would not charecterize them as fragile, just not tough. Also, there are wire Kojaks and folding Kojaks, both in 406 and 451 so we are talking about four different tires.

Panaracer Minits Lite or Tough. Maxxis Torch.
