I recommend this product
Consno max loading indication
Prosinstant rack mount, single piece construction, simple
Casted and machined to size, by virtue, such construction improve product strength and reduce weakness points.

This is a great piece of accessory that can instantly give you a rack mounting eye.

The only regret is that manufacturer does not provide max loading test result. It will difficult to verify the safety of carrying a 150 lbs pillion.

M Wave Seat Clamp For Carrier
25 Jun 2015
The seat post on my bike is 30.9mm and the tube it slides in to is around 34mm and I am not sure which size of clamp to buy, can you help on selecting the right size ?


SJS Customer Service:

Normally if the seatpost diameter is 30.9mm then the seat tube where the clamp fits to will be 34.9mm. If this is what yours measures then you can fit the larger size clamp in place of your current seat collar. If yours is a different size, then you will need to go for the smaller size and fit it directly to your seatpost with a shim to account for the difference in size.
