Question: Converting Topeak baby carrier to rack for groceries One reviewer noted that a steel rack would be best to support the weight of these baskets when filled.  I use the Topeak aluminum rack to hold a baby seat and now want to convert it to use with these baskets.  (http://www.amazon.com/Topeak-BabySeat-Child-Bike-Sliding/dp/B000ZKHNHS)     Is this rack strong enough?
Document: These were a little difficult to install; however the 2nd basket went easier than the 1st. The baskets are very heavy and with 2 on my back rack I can no longer lift the bike. When fully loaded it is difficult for a girl to handle the bike.
Using these baskets is easy as they are sturdy and hold two Trader Joe's polypropelyne bags relatively easily. The problem was the installation hardware was inadequate and thus we ended up buying two longer bolts to finish that installation. Also, the brackets that locks the baskets into the folded position could be easier to operate for those with any kind of impairment.
Answer: no
