Whats lighter- Hi ten steel- or- cro mo ?
Kristina D on Dec 12, 2017
BEST ANSWER: Good Day Kristina,
Whether a Chromoly Bike or Hi-Ten bike is heavier will depend on the components. Weather or not a tube of Chromoly is heaver or lighter than a similar tube of Hi-Ten Steel is not a simple answer unfortunately. There are a couple different types of both materials. Chrome Moly, 4130, is carbon steel + a trace of Chromium and Molybdenum, it has a way higher potential tensile strength, but tends to be a little heavier. However, that can be adjusted by reducing the tube wall thickness.... without compromising strength. 1010 Steel is OK too, commonly the tube spec lets the wall thickness be a bit thicker , so weighs a bit more , but will still be adequately strong. Basically... the weight of both materials will vary depending on how they were manufactured. I cannot compare weight by materials.
Are the pedals plastic or metal?
Scotty on Dec 31, 2018
They are Nylon which is a form of plastic.
Do these ship assembled or do I have to put it together?
Scotty on Dec 27, 2018
BEST ANSWER: The bike wil come in a box, and you will have to install the front wheel, handlebars, pedals and seat. Inflate the tires, safety check and ride. We have some great how videos on our You Tub channel.
Does it come with a warranty?
A shopper on Sep 9, 2017
This GT Performer will come with a full manufacturer warranty. BMX bikes (because they get abused) have slightly limited ones. From GT: GT frames 2015 model year and newer are warranted by GT Bicycle Corporation against manufacturing defects in materials and/or workmanship for the lifetime of the original owner. All other components, frame fixtures and finishes (paint and decals) are warranted against manufacturing defects in materials and/or workmanship for a period of one year from the date of original retail purchase.
