Hey guys,

I bought a new road bike it came with tektro r540 brake calipers, I want to replace them with shimano 105.... Are all the new 2013 and up 5700 105's the same?? Reach, mounting ect.

Thanks,
KF

Reach and mounting are the same for all current and recent 105 brakes (except the relatively rare long reach version). However BR-5700 model brakes require a somewhat longer cable pull than earlier ones, sort of between standard calipers and V-brakes. Unless you have 5700 or 6700 brifters, you should use BR-5600 model brakes or earlier. Older brifters or brake levers will work with 5700 calipers but the lever travel will be longer and the braking may be a bit more touchy.

I just replaced the 105 series brake calipers on my Domane 4.5 and my wife's Domane 4.3. I put Dura Ace 9000 calipers on my Domane 4.5 and I put a set of Ultegra 6800 calipers on the wife's Domane 4.3. It was an easy swap. The Dura Ace 9000 calipers work great with my Ultegra 6700 control levers and the Ultegra 6800 calipers work great on the 105 5700 control levers. The 105 calipers should bolt right up without any issues. I have two sets of 105 calipers set aside now after this upgrade to our bikes. I may put one set of the 105 calipers on my daughters Lexa SLX to replace the Tektro r540 calipers it has.

I don't know if this helped you or not.

HillRider

Yes, they should. All of the components you list have the newer cable pull requirements so everything works together as designed. The OP's Tektro brakes require the older shorter cable pull levers and current 105 BR-5700 calipers are not an exact match.

Domane

Maybe I misunderstood the OP when he said he bought a new bike, I was thinking he bought a 2013 or 2014 model year bike.

Our daughters Lexa SLX has 105 5700 controls and tektro brakes.

Thanks guy's,

I bought a new left over 2012 Jamis xenith comp and it has the BR-5700 levers so im thinking the 2014 BR-5700 calipers should be good ??

I live in the Cape Coral area, let me know if I can help you out as far as a set of 105 brakes goes. I have two sets one with 340 miles on them and the other set only has 18 miles on them.

Sounds good thanks.

Sure, you do have the matching levers so no problem. It wasn't obvious in your OP.

Thanks for the help. I didn't mention the levers i didn't realize they mattered.... I was thinking about the caliper reach to the rim and didn't even consider the levers.I learned something new today thanks again for the help.
