These pedals appear to the Look PP66 - use the Delta cleats for them. The red cleats give you rotational float, black for fixed position. As others have pointed out, the Keo cleats cannot be used, as they are smaller and a different shape than the Delta.

You’re right on. The road shifters have different pull ratio, so you need to use a road front DR. A Sora triple front DR will likely work.

In case someone else finds himself/herself in my shoes, here's how it all turned out for me... so, the previous FD was a 2x9 Shimano Altus and it still managed to move the chain from one chainring to another. Since there was no 3x11 option with a different type of pull, other than front, i took a chance and ordered a 3x10 Deore SLX. Besides the usual min-...

Shimano says the Tourney level TX-505-8 hub is compatible with 8-10 speed cassettes. Mountain bike 11 speed cassettes fit in on a '10 speed' freehub, because the larger inner sprockets can extend off the inner end of the freehub and not interfere with the hub and spokes. On road bikes where cassettes have narrower ranges and smaller inner sprockets the ...

I did some looking around and was surprised by the lack of options for a proper ramped and pinned 42t 130 middle. But, there's still TA, the Alize model in this case. Don't get a non-rampy chainring to use with STI. It's too much of a compromise. FSA has one too.

Ultegra 6500 components are a 9-speed group made in the early 2000s and maybe late 1990s. The bolt circle diameter (BCD) on all performance-oriented Shimano road cranks of the time was 130mm. Thus, any chainring with that BCD will fit. Dura Ace 7800 was introduced in 2004, and the BCD was still 130mm. Thus, that chainring will fit. I don't know if the ramps ...

reliable interchangeable parts is a trade secret with tiny insights hidden in places across the internet. I disagree with that. The information is out there and is not a secret. Shimano publishes a huge trove of information about their products including detailed specifications and compatibility, with an archive going back to 2004. SRAM is not so great ...

If you want something utilitarian and practical leaning, the closest thing to your "Thinkpad and not a Macbook" analogy is going to be something from one of the spare-parts-bin-oriented frameset companies like Surly, Soma, etc. If you want something more mainstream and performance-oriented, you'll just want to avoid bikes with proprietary gimmick ...

I have XTR M9100 brakes. Recently I have replaced the front caliper with a XTR M9120 4-pot caliper with excellent results. The rest is absolutely the same, hose, levers, etc. Only the front caliper changed.

Is this because the parts are incompatible? Yes. As groupsets with greater number of sprockets in the cassette were developed, the sprockets were spaced closer together to fit them in the space available. 11 speed road cassettes are slightly wider than 10 speed but the sprockets are still closer. The chains for 8, 9, 10 and 11 speed groupsets are also not ...

Any Shimano compatible 9 speed road shifter like the Sora you linked will work. While it will be visually different it will perform the same function. The last of these models were produced in 2007. While the Sora shifters you are looking at may be lower on the hierarchy list, they are likely equal to or better than your nearly the 20 year old technology you ...
