I ramped up the PSI from 40 to 50... 25% increase.

Yes I did notice an improvement! But I am well exceeding the safe range to run these, toss in the kid trailer and I really would hate to blow a tire pulling them. So I figured since I did notice a a nice decrease in rolling resistance I need to change out to a higher PSI tire so I can take advantage of it without living on the edge.

From the recommendation of another forum member I picked up Kenda Kwest High Pressure 26x1.5 Black. They have a higher pressure rating of 100 PSI and they are slightly more narrow.

Ordered em form AE Bike and they are on the way!

That will improve things no end- Decrease in width of the tyre and 100psi will be far better.

And don't forget that you will need new tubes.

Yep I got 3 of them so I could carry a spare. I actually ordered the wrong style at first, thanks to some forum members they warned me in enough time to change the order!

I hope it does, seems many here are on the fence on if it will make that much of a difference. I know it won't make it any worse, possibly the ride rougher but I'm willing to do that to take the chance in making the ride not feel like I'm always trudging through mud.

Nothing personal, but at 240 lbs. you're hardly a freak of nature. There's lots of riders out there that weigh far more than you. I weigh 225- 230 and get along just fine. I have no idea what your height is but just make sure your bikes are set-up to properly fit you and your spouse. That's a problem with Wal-mart bikes, one size only. Better tires will help, but you may never get truely comfortable. Never could figure out why they call them comfort bikes, "cause they're usually anything but.

One other caution in moving to high pressure tires.

When I moved to a high pressure tire on a 26" rim, I had some trouble with flats due to flats caused by the rim/spoke heads which was handled by getting a better rim strip. Things that are no problem at 40-50 PSI can be a problem at 80-100 PSI. I also ended up going to a thorn resistant tube just for extra insurance.

And a lightweight like you will have fun cycling on higher pressure tires... I have 100 pounds to lose to get down to your weight.

Thanks for the heads up, if I keep getting flats I wont have to wonder why.

And thanks for the insight Norwood, I understand now that I am not that big. (been hanging out over on the Clyde forum since last week) I also understand that this bike may not ever feel perfect, I have been adjusting it during / after each ride tweaking it to get everything right. Trying to at least make it "ok" until the day comes when I can pick up something perfect for me. I think I have the seat height right, my legs are almost fully extended on the stroke. However they kind of don't feel in the correct place under me. Kind of like they need to be moved forward some. I finally also got the handlebars up some so I wasn't sitting on my hands as much. Carpal tunnel is already a problem and it was causing me a lot of discomfort.

I appreciate all the help!

Just a thought on the carpal tunnel.

Just a thought on the carpal tunnel. You may have already done this. You might want to try some padded gloves and/or nice thick sponge grips( if possible). I too have problems bearing weight on my wrists for very long, and these have worked wonders for me.

Just remember, you wanted an inexpensive bike. Now add the tire cost and tubes, wheels, and anything else that doesn't feel right. Total your expenses and then go to a reputable lbs and look at a few hybrids (even used) and compare your box store bike to the one from an lbs. I'm speaking from experience. Got an old WM bike hanging in the cellar. Got tired of investing for upgrades and got a used GT at my lbs and I love it. Don't fix it---junk it. There are bike shops who operate just to fix old junk and give it away to kids who otherwise would never have the cash for a real bike.

I know I dropped 75.00 on tires, tubes and a few small items. Bike was 120 new. I refuse to do anything else though, no more upgrades. Next spring I will be buying a lower model Trek or something. I need to prove to myself (and wife) that I will keep up on it before dropping that much money. So far so good, and loving every minute of it!

Kenda Kwest comes in either 1.25 or 1.5". I'm sure your LBS can get them, or you can get them here.

Will it be an issue, spending $60+ on tires for a $99 bike?

I already ordered and received those tires in the 1.5 high pressure model. They actually got delivered today about 30 min ago. I don't feel spending the amount was that big a deal considering now total invested amount has been 180 bucks. And unless something breaks that simple to fix I will not be "upgrading" anything else as I said. I need this bike to last me until next spring, if it does that I will be happy!

Oh and I only paid 24 for them from AE bike!

Comfort bikes are not for going anywhere. they are chairs with wheels. If you want something faster you should get a different bike. You also didn't mention how much you weight.

To answer your original question, yes higher pressure smoother tires will help your pedaling feel easier. try not to compare your speed though with other types of bikes which are meant to go somewhere efficiently, meaning with less effort.

FYI: I bought a hyrbrid and was disappointed with the speed, so I changed the tires and swapped the bars for drop bars. It's faster now. I don't think one can convert a "comfort" bike though. Plus it would cost some money.

try some new tires. I got some smoother tires for my kids' mountain bikes and I expect them to go faster and not work as hard when they pedal on paved bike trails.

I don't think anyone has mentioned it, but besides tires, are you shifting your gears? Spinning an easier gear is better than mashing a big gear.

Yes I am shifting, however the bike only has 7 gears. So steep grades are really tough on me.

Actually this is one of the things I misunderstood for some time. Whether 7 or 11 gears on the back, bikes don't necessarily have higher or lower gears as the number of sprockets incereases... they tend to add more gears in between as the number of sprockets go up.

I have an 11-34 cluster on my 8 speed comfort bike, and an 11-28 on my 10 speed road bike... On my 10 speed cluster, it is the widest range my road derailleur could handle, so I actually have lower gears on my 8 speed than on my 10 speed.

In fact, 34 teeth is typically the largest cog (so lowest gear) whether you have 5 cogs or 10... if your drive train will handle it.

Oh nice so your destroying my excuse!

Good to know though, I found pulling the trailer up a slight incline in the lowest gear impossible without standing up. These stupid shocks are annoying though, I can tell it "bounces" a lot, wonder if I can tighten them up.

Guys/Gals I need Help Semi Slick Question

First of I would like to say I am 6'3" and 340 pounds. My mountain bike I bought last summer is a "L" Giant Rincon. My mountain bike Knobbies have been great. Since Last summer I lost 30 pounds and am riding about 50 miles a week. I want to step it up a bit. With that said I would like to go to a semi slick tire. I do mostly road riding now and hardpack campground/state park trails. Even with a road tire I think it could handle the trails I ride on. With that said I am very concerned about semi slicks because of the possible flat factor. I went to my LBS and they had Kenda Kross for 20 each. They seemed nice and the gentleman at the LBS said they will do just fine with my Weight. All flats have to do with road/trail debris. any advice on a nice Semi-Slick?? thanks for the help guys/gals.

Tim
