Zefal Spring Bottle Cage

I recommend this product

Really good cage from Zefal - works equally well on the downtube and seatube. Better than any other cage I have tried.

I recommend this product

The simple cages hold normal bottles well and don't increase the overall width much so work well if your legs run close to the cage. They are made of strong plastic. The bolt slots are quite wide so if you use a normal cap head bolt, it is worth using washers both sides to spread the load and smearing some mastic or loctite on the bolt threads to keep water out of the frame tubes.

I recommend this product

Good quality plastic that provides a strong but flexible hold on water bottles. Looks excellent on my black MTB, and holds a bottle firmly so it doesn't fall out on rough trails.

This is a good cage, great value and very lightweight, but be warned: to fit it on the seat tube, the distance between the centre of the lower bottle cage boss and band of the front mech has to be around 40mm or more. Otherwise it won't fit.
