Debating on whether or not my Allez will be able to pull a trailer with my two children? Any issues pulling a trailer with a road bike?

It's made out of aluminum...not glass. It's just depends on what the seatpost is made out of if it mounts that way.

It's doable, I've done it once or twice while the mtb was out of commission. Just watch out for sharp corners turns. I would say if you plan to do this a lot just buy a beater off CL, it will be much more comfortable.

Pulling kids with a road bike make it handle really twitchy. I'd suggesting getting some wider bars, turn it into a flat bar road bike or just get a mtb. I used to pull my son on my Salsa Vaya which used had 42cm bars instead of the normal 40cm I usually used and it still made the bike handle really squirrely.

I had a trailer for my kids and towed it behind my old steel bianchi. I hated it. The trailer clamped to the chain stay on the left side, and there was a pretty stiff spring that gave the trailer some "give" when I pedaled. Well, it felt like I was being pushed at all the wrong times and pulled when I was trying to push, but not consistent in any way that I could become accustomed to. It was awful. And heavy. It's hilly where I live so the trailer hasn't been used in years. I'd rather floss my teeth with barbed wire than use that damn trailer.

If you can test one out. There are probably much better models that are pleasant to use.

I used to pull my kids in a Burley trailer on an older model steel Allez. Never had a problem. I finally decided they were getting too heavy for it when they turned 15.

You just need to HTFU!

I think my trailer was a Bell so get a Burley instead.

This is my set up, I loved it, it’s absolutely brutal on hills, I ultimately decided it’s too hard on the bike.

The thing I've noticed in pullng a cart or trail-a-bike is that it's much easier to control with wider flat bars than narrow road bars. Especially with the trailabike where the kid is pedaling -causing some swaying. That can be downright hard to control with narrow road bars.

My guess would be in 14 years they figured it out one way or the other and I think at this point all the people involved are no longer active.

I concur with the suggestions about obtaining a (sturdier) used bike for the purpose. WAY back when my kids were that age/size, and I wanted to take them along for rides…I opted for a (used) steel road touring bike. It also had somewhat larger/sturdier wheels. But I didn’t pull a trailer. I went with a rear-mounted child seat. It worked out well, and I used it for several years for both kids. Just a note for you, or those who do go with a seat instead of a trailer: The key be being able to ride longer is ensuring the child is satisfied. Make sure you have everything for diaper changing with you. Additional considerations for the kid: sunscreen, sunglasses/goggles, snacks and drink, and toys. And remember…ANYTHING that the child has should to be tied on or you’ll be backtracking frequently to fetch things they discard. And don’t make the rope/string so long that it gets tangled in the spokes. Have fun. — Dan

Depends on the hitch attachment and trailer design. I pulled kids in trailers for thousands of miles with no issues,

Get a multi-speed cruiser bike off Craigslist or similar, it'll be much easier to handle with a kiddie trailer. After the kids are too old for the trailer the cruiser can come in handy for teaching the kids to ride a bike, utility riding in the neighborhood, etc. I'd suggest multi-speed (even 7-speed) as the lower gears are handy for pulling a trailer, higher gears with no trailer and you want to get somewhere a little more quickly,

esp at slow speeds. Plus, OP has 2 kids.

I have no experience with towing 2 small children. Used a large rear rack mounted seat + trailabike when 2nd could sit upright. Also had a solution when the younger could be trusted to hang on.

I wonder the differences in towing a 2 wheeled cart, verses a single wheeled ... 'something for 2 + dog companion'.

The cart is much easier. Not much of an issue actually, iirc (it's been 30 years!) because of no much side to side movement. But still easier with a MTB/flat/wider bars. I recently rode with my grand kid on a trail a bike with a cross/gravel bike with normal width drop bars. I had to be VERY careful when encountering anyone else on the MUP. I got to the point where I would tell her to stop pedaling. I recommended to my daughter and son in law to get a cheap flat bar bike to pull it with. He (son in law) is much younger of course and much fitter and probably able to deal with the sway, but still....

Judging from the OP date, I’m going to go out on a limb and say they are no longer kids. At least not ones who need pulling.
