ShimanoL03A Resin Disc Brake Pads(Return to Product Page)

These came with my road bike (105); I didn't buy them from BikeTiresDirect. They're so quiet and have great stopping power, so much better than the brake pads that came with my commuter bike which also has disc brakes (Tourney). I climb a lot (like I find the Strava monthly 7500 m climbing challenge too easy) and I brake a lot in urban areas as well as there're so many stop signs and traffic lights. The rear one lasted over 1800 miles; actually I'm not sure if it was really all that worn down as I never checked it myself and the mechanic replaced it when I dropped my road bike off for a tune up. Like most people, fearing flying over the handlebar, and especially that I'm right handed, I brake more with the rear brake. The front one still has some life left after over 3800 miles, but I should replace it soon. I really love these brake pads. Too bad they're so hard to get. Or no wonder they're so hard to get and are gone as soon as they're available.

I live in a very hilly area and in the summer it gets very hot here in North Carolina. The added heat sink helps keep the temps controllable with all of the downhill runs I have. Wish I could put them on my other bike but they don't make them for the Sora line. These pads were a noticeable improvement the first 1/4 mile I rode with them.I highly recommend them.

Never have any problem with these. Braking is good. No squeals except when wet... but so do all pads.

I would like to get a bit more wear out of these. That would be my only complaint. Otherwise good pads.

replaced metallic pads with these. They are way thicker than the ones I used previously. I personally think they are smoother, quieter and easier to modulate on downhills. Can't speak to wear yet. Easy install using a plastic tire lever to push the hydraulic pistons back.

I use these on my gravel bike and they work very well. They are easy to install and provide excellent braking quality. I generally get 6-9 months out of a set.

Great Product

Exactly as ordered, delivered on time.

After checking all the competing pads available, I found most reviews pointed to sticking with Shimano's OEM pads. The original set lasted long and didn't have any negative impact on the rotors. So...I'll keep buying these.

I use these on 4 different bikes for road, commuting and cyclocross. They are quiet and provide good consistent power.

I am still on my original pair of these disc pads. They are very, very easy to remove, inspect, clean andor sand if necessary - perhaps a bit easier to service than rim brake pads due to access. But that is open to debate. Cooling fins are not necessary for flatland use. I cannot comment on effectiveness for long hill or mountain descents.

These pads provide excellent stopping power and modulation. Excellent control.

Quieter than metal but wear much faster. As long as you can do your own maintenance the cost to wear differential is worth a quite ride.

This latest pad (L03A) is a solid improvement in longevity over the prior L02A pad. The L03A pad wears more slowly than the prior Shimano resin pad, with easily equal power. In fact, the newer pad seems to have a small increase in absolute braking power. In all meaningful parameters, the new pad is an improvement.

My Moots is equipped with the 8070 Ultegra Di2 Hydraulic setup. I ride my bicycles in all weather conditions, including brutal downpours in the Pacific Northwest, mud, gravel, and grime. The Moots is no exception. These Resin pads replaced the Metal pads which were on the bike originally. They have great stopping power, and are easier to modulate than their Metal counterparts. However, Metal pads will stop harder and in harsher conditions. Make sure that you buy the ones you need before you order. Generally... I run Resin during fair-weather times of year, and Metal during drenchy, drippy winter conditions. Resin pads wear a bit faster in exchange for better control over stopping power (and less wear on rotors.)

The Shimano L03A replacement brake pads offer good stopping power with fairly quiet performance. Too early yet to evaluate Shimano's claims that the L03A pads last significantly longer than the L02A pads that they replace. However, even if the L03A longevity is as good as their predecessors, then I consider them very good.

Though I am relatively new to disc brakes, I was very pleased at how easy the replacement of disc brake pads was. Just follow the steps Shimano provides, and the task is done in 5-10 minutes per set. Easy!

they installed easy, don't squeal like my old pads did.

These pads don't look much different but I can tell they are lasting longer already. No squealing except when riding in the rain and they all do it then,

Shimano LO3A are easy to install. They are quiet, , smooth and long lasting disc brake pads.

Use these on the road bike I ride in the rain. Bought them to replace metal pads that squealed like crazy. These are quieter, but they still squeal. I don't know that it's the pad's fault though, I think maybe the rotor Shimano uses for their Ultegra set just might be noisy in the rain. In any case, it is an improvement.
