32T Cassette/Derailure Options

[aerobrain]

Hi

I'm doing C2C in a few months and have come to the conclusion I can't beat gravity!! I believe some people use a 32T cassette on their road bikes but from what I can see only MTB cassettes have that option.

I'll probably only need that kind of ratio once in a blue moon so don't want to spend a fortune. But conversely, doing 150 miles I don't necessarily want total bargain basement.

My current thinking is a 12-32 MTB cassette with maybe a 105 medium cage mech. I'm on a compact chain set and Tiagra shifters.

Any recommendations for specific cassettes or mechs greatly appreciated!!

Cheers

Lee

It depends on the bike, but 32T will be pushing it with a road mech.

Some will fit 30T without issues.

9 speed shifters work well with Deore MTB mechs, as for 10 speed, i dont know.

Even the pros use these ratios sometimes. If you need it, do it

I have a SRAM Rival set up with 32T at the rear.

Unfortunately a complete groupset change is out of the price range :-)

A 9sp MTB rear mech will work fine with a 10sp shifter. Would allow a 34t cassette if you wanted it then

Yeah that's kind of the thing I was thinking. Although I'd like to go for a 12-32 to give slightly better cadence gaps. I know SRAM do that range in their MTB cassettes. Am I right in thinking SRAM MTB is interchangeable (for cassettes/chains) with SHIMANO even when mixing MTB/Road?!

Cheers for the help guys

I appreciate that but I mentioned it because it's in all other respects it's a perfectly standard road bike. Oh and, me too, I'm useless on hills.

Yes, SRAM and Shimano cassettes are compatible with each other. SRAM tend to be more expensive that's all.

My Giant Defy 4 compact has a 32T cassette.

 

[MikeW-71]

Yep, so does my Brothers Defy 3 with Sora.

How do get on with Double Tap? Next year I plan to change the lot and I'm very tempted to go for the Force 22. Tried it briefly at the cycle show and seemed more intuitive than I expected.

Very quick adjustment for me. I've 3 bikes, 3 different systems. After a while of riding one bike exclusively I can forget and look for the bar-end friction shifters on the double-tap thingummy but, as that means grasping in thin air, I very soon remember. The system very soon gets associated with the bike, its frame, its ride.

I have a 8 speed 11-34T cassette on both my run of the mill road bike and my hybrid “tourer” I changed the working stuff to Alivio. Compact on front of road bike and a triple on the other bike. Cheap stuff, but works ok.

Can you go with a 12-30 ? 10 speed Tiagra here for £15 and just fitted one to one of my road bikes for the hills (105 compact) no issues other than adjusting the B screw .
