Re: Road bike Commuting up hills - 16, 22 or 24 Gears?

Do they still make triple variants of the fancier road groupsets? Nope, Tiagra 4700 is the highest current shimano groupset with a branded triple (this mostly appears to be 105 5700 with a respray tbh). Essentially as Shimano sets moved up to 11spd they lost the triple. I'm pretty sure campy don't ...

Re: Road bike Commuting up hills - 16, 22 or 24 Gears?

Depends entirely on the available ratios between back and front rather than the number of gears. Triples typically have a larger overall range of gears than doubles but a 2x11 setup will generally just provide finer increments than a 2x8 rather than more range (depending on cassette choice) Without ...

Re: Costing up Changing Double Front Chainset into a Triple

Yes, you'll just have larger jumps between gears. Your current cassette is 12.13.15.17.19.21.23.25. The standard 11-32 8spd hg50 shimano is, iirc, 11.13.15.18.21.24.28.32. Whether this bothers you largely depends on how much you like to pedal at a specific cadence. Obviously other cassette options a...

Re: Costing up Changing Double Front Chainset into a Triple

Meanwhile a new cassette is a tenner. According to shimano the short cage rd is 37t total capacity so in theory an, eg, 11-32t would work with a 34/50 compact though the gaps would be largish. Is your hybrid 8spd? If so could move the cassette over from that for testing purposes. You still might nee...

Re: Which tyres????

Be a bit careful comparing folding and rigid tyres even of the same or similar sounding models, I'm sure sometimes the difference is more than just the bead. That is a good point. Some manufacturers will have a number of sub variants for each tyre model name with different compounds, casings and pr...

Re: Changing double to triple - BB choice/Crankset choice?

The cx front mech is designed for doubles not triples though. Regarding the overall capacity issue how about a mtb rear mech? As long as you stick to '9sp' or lower the ratio is the same as the road so will work ok with the 10sp shifter. Eg an alivio rd-m4000 is stated for 34-11 (or 36-12) and has a...

Re: Shimano R517 Adjustment

I'm not suggesting using the cable to adjust the brakes for pad wear and I don't believe Padraic was either. He appears to be talking about the small amount of slack at the beginning of the arms movement that results in no pad movement which seems to be something specific to the design of these R517...

Re: Shimano R517 Adjustment

Hello, I have these brakes (well actually the CX77s but they're basically the same) on one of my bikes. The 2.5mm screw does not remove any arm travel, it just pushes the piston further round (and so inwards) relative to where the arm is (the end of the screw is what actually pushes the mechanism wh...

Ah, makes sense, mis understood what was meant by 'mechanically propelled', misread it as manually propelled.
