Defy zero cassette

Fil6914

Hi guys

Need a little advice please, I'm struggling up the hills at the moment so thought about getting a 12-30 cassette to help me up until my fitness levels improve to be able to drop back down to the 12-28.

My question, is it just a matter of swapping over the cassette without any other adjustment or is it more involved than that ?

Thanks Phil

I have a defy 4 and I swapped to a 12-30 cassette no trouble. I will say that mine has shimano 2300 rear mech and is 8 speed .Maybe what you have might not go the extra, though from a 28-30 isn,t that big a jump.

How Far is too Far

I would agree with the above post.

I have used one with an Ultegra set up no problems.

The only problem you might have is if you ever went into 50t front and 30t back, but this should not really be a problem.

I have a 30/12 Tiagra cassette with no more than 100 miles use with original box if you want to make me an offer

Agree, it won't be a problem. Technically you'd add a link to the chain, but you'd get away without I think.

Yes it will work, I swopped my 12-28T for a 12-30T CS-4600 Cassette on my bike. You will need to adjust the B Tension screw to achieve the correct clearance between the 30T sprocket and the upper guide pulley wheel of the rear derailleur. I did not add any extra links to my chain as I never use the Large F - Large R combination.

When I started back on the road three years ago, with a compact 50/34 and a 12 /27 on a defy 1, I was struggling on the hills. Now, three years on, I use my old hack for winter riding,(Giant Speeder, steel frame, 53/39 and an 11 / 23). And I ride up the same hills. Maybe not as fast as with the compact, but then it is winter. My point being, don't change your cassette, change your mindset. If it hurts, take a rest. If your slow, don't worry, you'll speed up. If you know your route has a hill coming up, take a drink, take a break if you need, start in a small gear and spin all the way to the top. You'll be suprised how quickly you will improve.

the 30t cog isn't that much of a jump from the old 28t cog anyway.
