Will I break this bike?

First, welcome to cycling and this forum! Lots of good advice here. As long as you keep the tire properly inflated you should have problems. That doesn't mean that you won't flat a tire from time to time, but it won't be due to your size. And the bike will be fine, too. Enjoy the ride! Brian in VA

I'm sure that what Brian meant to say was that if you keep the tires properly inflated, you should NOT have any problems. 260 is not a lot of weight for a bicycle, tires or frame. One thing that you definitely want to do is visit your local bike shop and let them fit you. A person with the wrong size bike will not ride it because it is uncomfortable. People with good fitting bikes tend to ride more and buy stuff from their local bike shop so it is in their best interest to make sure that the bike that you purchase is the right size.Get the bike, enjoy the ride, and kiss 260 lbs good bye.

There are many heavier cyclists [also called Clydesdale's] here at the forum and on roads and bike paths everywhere. I've lost some weight myself... very much, due to cycling... but weighted 257 pounds just last November.

I rode then and still ride my aluminum road bike with C25 tires. I admittedly don't know the actual limits of a modern bicycle. But I do know that millions of the worlds bicycles are "push bikes" and used to haul or carry heavy loads. But I try to be extra careful when on the crappy potholed urban areas I often ride. I haven't had any problems with my entry-level ($650 on sale) Fuji in the last 2 1/2 years [over 3K miles] I've had it. I do check my tire pressure every time I ride my bike... as well as keeping the bike clean and properly oiled and such.

I went to my LBS today and got fitted for a large Rapid 4. I voiced my concern about the tires and he said as long as they are properly inflated... I will have no problems. They said they needed to do some final tuning so I came back in an hour and it was ready to go. I went biking with my girlfriend at a popular bike path and had a blast.... however, after 20km... i got a flat on my front tire.

Do I just have the worst luck? The reason I bought the bike was because the guy at the LBS said I will not have an issue with flats. I wont be able to afford getting flats fixed everytime i ride. This discouraged me quite a bit despite how much I had during that 20km.

So I assume flat tires are not generally covered by LBS.

When I get a flat... is it always going to be the tube? Or will I often get problems with the tire as well. I feel I can splurge for the $5 tubes 🙂... but the $50 tires will hurt the wallet.

Thanks

That's interesting as I had my first flat today, too. Mine came after about 1100 miles, though. You apparently have bad luck. May I suggest you do a quick search of this forum and YouTube for info on how to fix the flat yourself thus avoiding the charge? That will save money in the LNG run. The other piece is to watch for objects that might puncture a tire while riding and avoid them whenever possible. Good luck! Brian in VA

Learning how to fix flats is easy and something that you should learn so that you don't get stuck on the side of the road a long way from home someday. Here is a tutorial on how it is done:

Or Park Tools website has an in depth tutorial:
parktool.comtire and inner tube serviceOpen ↗

Typically the only part that is damaged is the inner tube and it can be repaired, but most people carry a spare tube so that they can just replace it if they flat on the road and then repair it once they get home. It is possible to have a flat that damages the tire casing and then you need to replace the tire. I have been riding for over 40 years and have yet to have a flat that destroyed the tire. It can happen but it rarely does. It is sort of like an asteroid can hit the Earth but..........

In order to minimize flats, you can purchase a pair of flat resistant tires like the Continental Gatorskins. There are also thorn resistant inner tubes that you can purchase. But watching for debris is your number one defense against flats. After riding, check your tires for anything that might be embedded in the outer casing as shards of glass or thorns that do get stuck in the outer layer of rubber tend to work their way to the inner tube unless they are removed.

Thanks for the advice. My LBS replaced the tube for free. I also picked up a patch kit and 2 spare tubes. The guy at the LHS told me to keep the tires at 100psi... However the tire itself says 120psi... Which one should I go by?

The tire sidewalls usually state a "Max Pressure" rating only, not a recommended pressure for a given rider's weight and riding conditions. Exceptions are Michelin race tires, which state a range on the sidewall : "Min 6 bar, Max 8 bar" (87-116 psi). For your weight, on 25 mm tires, I'd say 100-110 psi is OK for front, but for rear I'd go to the max, 120 psi. When your rear tire wears out, you may be able to replace it with a wider 28mm tire, which would give you better ride and longer tire life with fewer cuts and punctures. 100 psi would be plenty for the wider tire.

Flats shouldn't happen that often, but you'll need to be able to fix them on the road so you can get home. With your brand-new bike, I wouldn't be surprised if the flat was due to a defective tube or problem with the wheel. The LBS should have carefully checked over the wheel and rim tape before installing your new tube to be sure spoke ends aren't sticking up. If it happens again on the road, try to find the hole in the tube. If the puncture is on the top (rim) side of the tube rather than the bottom (road) side, look for a sharp spoke end poking up through the rim tape.

I went through a period of flat tires myself. I followed all the normal procedures and inspected the tubes (and tires) in an effort to determine the exact problem/cause. I inspected the routes I ride most often looking for road hazards that could have been the source of the flats. I also reexamined most own riding style to make sure I hadn't developed new bad habits that would make me more exposed to road hazards.

In the end.... I gave up looking for the cause of my plague [of flat tires] and took the bigger hammer approach. I purchased thorn proof tubes. They are twice the cost and several times the thickness of regular road cycle tubes. NOT a perfect solution! Flat proof tubes increase rolling resistance and slow down the cyclist. That was hundreds of miles ago, and so far, no flats.

I still carry all the needed tools and supply's in my saddle bag... just in case. An occasional flat isn't a big deal. But when I began to wonder about how many tubes I should carry on a 20 mile ride. I felt like I needed a solution.
