Can you use two different shifters (eg. Left-Tiagra,Right-105) on the same cockpit/handlebar?

The shifters on your left and right side don’t have to match. They can even be from completely different manufacturers. On road bikes it can be problematic because when riding “on the hoods” (the ...

Brake cable reach

I am somewhat confused by your description " they need pulling almost to the handlebar to brake". If you actually need to adjust the bite-point, that is done by tightening the cable at the ...

Are ST-5800 shifters compatible with hydraulic brakes?

As an alternative to the expense of upgrading to hydraulic STIs, there are cable-to-hydraulic adapters available. I recall seeing some Genesis road bikes equipped with them in a local bike shop. We ...

Are ST-5800 shifters compatible with hydraulic brakes?

You need to change your shifters. Brake levers designed to pull wires cannot be modified to push fluid. You might choose to install hydraulic brake calipers that are cable-operated but that's just an ...

Upgrading a 105 R7000 to 105 di2 R7100

Shimano has a pretty good compatibility chart. These things are "incompatible" according to the chart 11/12-speed drivetrain, I guess that should be clear, so the rear mech won't deal with ...

Shimano components upgrade - Claris/Tiagra to 105 R-7000

A much less invasive path would be keep the cranks, STIs, and rear wheel you have, go to 52/42/30, get an FD that can accept the 10t jump (none of the 50/39/30-era Shimano ones can), and then either ...

Shimano components upgrade - Claris/Tiagra to 105 R-7000

First of all, Shimano 105 is a nice sweet spot price-to-performance-wise, and would be a nice upgrade (I transferred an Ultegra 6800 11-speed setup to a 1994 Trek frame that I use on the trainer with ...

Shimano R8000 right crankset compatibility with 105-5800

You are good to go with what you are proposing. You may also need a FD-7000 (or FD-8000) front derailleur. There is a very minor difference in the FC-8000 vs. FC-5800, but it is truly minor. Both ...

Claris crankset compatibility with 105 components

An 11-speed chain will provide terrible shifting on an 8-speed crankset with an 8-speed FD. The chain is significantly narrower on the outside. The usual rule of thumb is that a one-speed difference ...

Can you pair a 105 10 Speed Cassette with a 10 Speed Tiagra Derailleur?

Yes you can, provided that the cassette range approximately matches the range and capacity the Tiagra derailleur expects. Any Shimano 10 speed cassette works with any derailleur subject to the range ...

Are ST-5800 shifters compatible with hydraulic brakes?

STIs include the internals actuating the brakes, i.e. the mechanism pulling the cable or the reservoir including the brake fluid etc. For this reason, they are not interchangable, even within the same ...

Can I replace Shimano 105 FC-5501 crankset with Ultegra FC-R8000

The two cranksets use different bottom brackets, so you will need a replacement BB. Something like the SM-BBR-60 has an MSRP of only $32. It does need different tools to install than the old Octalink ...

Use Shimano 105 R7000 shifters for Disc brakes

The R7000 shifters are 11-speed shifters and require 11-speed pull ratio rear deraileur and 11-speed cassette. I'm not sure if your Tiagra is 4700 or earlier. If it's 4700 then despite being a 10-...

Claris crankset compatibility with 105 components

I think you could give it a try. Check to see how the 11-speed chain engages the Claris chainrings. Also check to see if the 11-speed chain will slip between the two chainrings. If it engages well and ...

Can you use two different shifters (eg. Left-Tiagra,Right-105) on the same cockpit/handlebar?
