I'm looking to buy a cruiser to ride at my local track with my little son who is racing a mini now. Can anyone tell me the difference between the Redline mx24 and the redline proline 24? Looking for some pros and cons. Thank you

You are getting two ounces less weight on the Proline according to the 2017 specs on the Redline website, and probably the parts on Proline are each mildly better than on the Mx24.

The Proline bike has a full chromoly steel fork, and handlebars. The mx24 mentions chromoly only for steerer, and the rest of the fork is thus likely to be so-called high-tensile steel. Ditto the handlebars, which are specifically called out as chromoly on the Proline. Brands will call out chromoly because it is a selling point.

Alloy cranks on the Proline versus chromoly on the mx24. Alloy is lighter in weight.

The above are items I notice from a quick look at the specs.

Thanks man, is there a huge difference between the cromo and alum cranks? Other than weight wise?

Aluminum have always been considered a more cheaper crank. Cro-Mo's can be a little lighter and stronger.

Racing cranks are often aluminum. I think the OP's son is planning to race.

For example: https://www.danscomp.com/bmx/Race/Cranks/

Yes but if you look at that page you'll see the Profile's which are Cromo are for the most part are much more expensive.

You make a good point though, if you're racing aluminum is good.

You're right. I hadn't spotted those. Wow. Spendy too. Nice looking, but spendy cranks for sure.

I just bought a cruiser for exactly the same reason, to ride and race with my young son. I bought a Flight Pro 24. In my opinion, the Proline is only marginally better than the MX24. I'd say go with the MX24, or go all the way to the Flight Pro......which is considerably a better bike. If you're out riding with your son, you can't go wrong with any of the choices.

Thanks man, that's exactly what I did,i ordered a mx24. I think my son is more impatient about waiting for it than I am. Lol
