The Tara low rider is a great rack. Something to consider is whether your bike has 700c or 26" wheels. Totally my own opinion but I find that with 26" wheels lowriders put the panniers too close to the ground for tight quarter riding near curbs and narrow trails. The 26"wheel LHT can carry front panniers on a top rack just fine but you have to move them far back enough that they'll overlap the brakes which may be a problem for some cantilevers but not for linear pull brakes.

this rack for 26" LHT



with the axle mounts removed the rack fits perfectly on the top dropout eyelet with a 1/4" spacers to clear the fork ends. I have it attached to the fork at the cantilever bosses and mid fork eyelet. It's a very solid and light set up.
