Just purchased a Synapse Carbon 5. After 5-10 minutes, my butt is hurting. Normal?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I'm a first-timer road biker, and my butt is hurting. Is this normal?

yes... both my butt hurts and my hands get tingly after long enough.. bike fits me well but when doing something for the first time it takes time for the body to adapt. On the plus side I learned how to true tires and adjust both front and rear derailleurs today thanks to some youtube vids. Make sure the bike fits you well and/or order a different seat.. thought about getting this one from amazon.. any thoughts?


some vids

YouTube - How to True a Bicycle Wheel
YouTube - ‪leonardmlee's Channel‬‏
YouTube - How to Adjust a Front Derailleur

bike shifts almost smooth as butter now, only some minor adjustment to the front needed yet to eliminate some chatter.

Yes, and your "sit bones" will be sore tomorrow. You will get used to it and will not hurt so bad. You may have to experiment with new seats. Give it 4 or 5 rides before you plunk down money on a new one, though. BTW, I have the same bike with the Prologo seat.

expect your ass to be tender for the first 10-12 days of riding, if you don't take more than a couple days off between rides...
if you end up off the bike for more than 4 days, expect to get 'recycled' like in basic training... Groundhog day over and over...
don;t bother messin with saddles before then, give it 30 days of ridin before you think you need to start the search for the holy grail of ass axes.

3rd/4th day usually worst, it get's better from there on, slowleeeeeee........

Even if your sitbones are super sore, at least do a 10-15 minute slow warm up ride. For me, it took about 5 minutes before the soreness went away, even on the bad days, then you're good to ride for the day.

just regularly, I would say twice a week minimum and the soreness will go away. if it doesn't, find a shop that will let you try different saddles for a week.

Your butt will toughen up .. it takes a bit of time. I'm assuming your wearing padded shorts / bibs. If not, you should seriously think about getting some.

As long as your junk is not hurting or numb, you'll be ok.

Install a saddle, it'll hurt less.

Go to your LBS and get a sit bone measurement, you may be on the wrong width saddle.

If this is your first road bike, your butt's gonna hurt for a while regardless of what saddle you have.

The one that comes stock on your bike (Pro Kappa Pas) is actually a pretty well regarded one. As noted above, give yourself time to get used to it.

I'm picking up the same bike next month - that's the only reason I know which saddle comes on it.

Demain, on roule!

It is the wrong bike. Box it up and ship to me. You will only have to pay for S&H.

No, it shouldn't hurt until you've been on it for 20-30 miles. There are a lot of adjustments/tweaks you can make. If they're right it makes a big difference in comfort over when they're wrong. Get a good fit from someone who doesn't just think racing. Maybe buy some padded shorts and gloves. Getting the right saddle is important, but it's hard to know what will be right until you've ridden on it for a few good rides.

Yes, it's normal for new riders. It's like wearing thong sandals for the first time, and the web between your toes hurt after 10 minutes. If the bike fits, the saddle is good, and your position on the bike is right, your butt will get used to it, and it will stop hurting soon.

Things to check for:
Is the saddle too high?
Is it tilted wrong?
Saddle fore/aft adjustment - are your sit bones properly placed on the saddle, and no pressure in your "sensitive" areas?
are you leaning too much?

There are some good resources on this site regarding bike fit, I suggest you start by doing a little reading about saddle adjustment. If all is done well, and you're still hurting after a while, look into getting a new saddle with those anatomical cutouts in the middle. I like Specialized saddles a lot. Get something not supper padded. And if after all that, you're still hurting, try to get a proper fit done by a professional.

Felt the same way. Thats about how long it took my debit card to clear Padded shorts are a big plus if your not using them, Ive heard some bad things about gel shorts though.
