It does not specify for what type of bike frame can be used.
Bad seller, I do not recommend. In 2 months waiting for the product to leave China, he just said it was late and did not check the delivery situation. I lost 2 months waiting for a product I needed and the seller paid no attention. terrible seller. terrible attendance.
The seller harmed me in 30 days without checking the carrier delay. I gave no information, just left me waiting. Until I complain after the deadline and return the money.
