I am getting ready for bicycle touring this summer. The tubus tara lowrider front rack is perfect ... light but strong and a great value. I had used another front rack on a trip last year but this was too heavy and did not get my panniers low enough. I should have gone with the best on the first purchase
I replaced my Surly front rack with the Tara Lowrider, and so far am happy with the decision - the rack is less than half the weight than my Surly. The rack is solid, and I can easily fit my Ortlieb front roller panniers on it. I will clearly need to play around with the positioning of the bottom clips on the panniers (the angles to get them engaged with the rack are more limited than on the Surly racks).
I did have an issue with getting the rack plus fenders installed. In my case I ended up needing to get a new quick release lever that would fit with the hardware and still function - for someone forgoing quick release levers for the locking variety, this is not an issue).
Only other minor complaint was aesthetic... on my Disk Trucker, the horizontal bars are not quite parallel to the ground. I played around with all possible installation points and it's just not possible (gave up after reading that this is a common complaint with the rack).
