Dear friend
We are glad that you are interested in our products.
We will send this bike booster as soon as possible.
Please send us a picture of your bike for us to see.
We want to analyze whether your bike can use our booster or not.
Booster three questions:
1, the booster can only use round seat tube, (other shapes of seat tube can not be used)
2, the booster maximum use 31.8MM round seat tube, (seat tube diameter over 31.8MM can not be used)
3、Our booster can not be used with Rear shock absorbing bicycles, (because shock absorbing bicycles will cause damage to the booster when riding up and down,)
We are waiting for your reply.
Thank you
If you have any questions, please let us know and we'll discuss it together.
Best Regards
Jason
