The body on the unit to the right and are magnesium these have 3 sealed ball bearings and spin effortlessly. There's an O-ring on the inside to help prevent road dirt from entering the bearing. Aluminum lock nut and black anodized end cap. Dis-assembly is very easy and only takes a few minutes. As you can see on the scale these weight 78 grams each.
Here's another popular pedal. This is the BiG pedal and has the largest platform that AEST makes. The version on the left has Gold Titanium axle available only at Toronto Cycles
We also offer axles in titanium anodizing and have all replacement parts on hand. At this time we do not have the steel axle units but should get some axles in the future. AEST has really been making some nice stuff lately. The pricings are great and it's hard to beat this quality for the cost. We will post a review on the 2014 hubs and also do a few wheel builds when the titanium spokes are finished.
