The road bike brake caliper of the Black Friday should be chosen with precision: a caliper for a classic rim or direct mount, a flat mount disc caliper, or a mountain bike model cannot be replaced by one another. First, note the type of mounting and the position, front or rear, of the caliper to be replaced, then compare the discounts from Shimano, Sram, and Tektro for this reference.
The selection mixes three families. The dual pivot rim calipers, from the Sora BR-R3000 to the Dura-Ace BR-R9200, including the 105 and Ultegra, with the R540 and R559 from Tektro and the S900 from Sram. The road disc calipers, mounted in flat mount, such as those from the Red and Force AXS groups from Sram or the Tiagra BR-4770 from Shimano. Finally, MTB calipers in post mount, XTR, XT, Saint, Code or Maven, which are not for a road bike.
The same reference is sold individually, front or rear, or in pairs, like the BR-R9200 set from Shimano or the Force front and rear from Sram: a crossed-out price can therefore be compared with identical content. For a hydraulic brake, the caliper must share the fluid from its lever: mineral oil for Shimano, DOT liquid for road groups from Sram. A Sram caliper does not replace a Shimano caliper on the same lever, even if the mounting is the same.
Tektro, a family-owned manufacturer founded in Changhua, Taiwan, starting with cantilever brakes, offers here the rim calipers R540 and R559, the latter available in recessed or bolted version.
Sram covers the road with flat mount disc calipers, Red and Force, and keeps the rim caliper S900 in direct mount, both front and rear.
Shimano brings together three generations of Dura-Ace calipers: BR-9000, BR-R9110 in direct mount and BR-R9200, also offered in direct mount under the reference BR-R9210.
Out of operation, bike road brake calipers detail reach, mountings and adjustments. During Black Friday, a rim caliper is installed with new road brake cables and housings and discounted brake pads; hydraulic calipers pair with brake levers for Black Friday. The clearance sale includes replaced generations, while the new arrivals feature the latest references.
Yes: the event, organized around the Friday after Thanksgiving, also covers road braking, and the discounts on calipers gathered here remain throughout November.
Look at the mounting: a single central screw for a standard caliper, two screws on either side of the wheel for a direct mount. The reference engraved on the caliper, with its suffix, confirms the version.
No, generally. MTB calipers mount in post mount, while road disc bikes use flat mount, and they are designed for flat handlebar levers.
Compare the same reference, in the same position and with the same content: a caliper alone, a pair, or a caliper delivered with its pads are not equal. Also check the generation, as newer and older calipers do not always have the same lever ratio.
A new caliper often comes with pads, designed for aluminium rims in the case of the Dura-Ace BR-R9110. For carbon rims, make sure to get suitable pads.
