Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

road bike gearing change !

I have an S-works with sram Force 53/39 & Ultegra 11-28 but still seems to struggle on the big hills.......I'm not small at 15 stone & could do with making the hills a bit more manageable as my friends are conciderably smaller guys.
Can I put a 11-30 on the rear? I think the rear DR is standard..........I have just chafed the 39t for a 38t but not sure this will be enough........

you might try a triple or compact ringset, up front. tough to understand your build w/o more info but, more miles will make you stronger. maybe thats all you need?

If you're using a Ultegra RD-6600 or RD-6700 your maximum sprocket size is 27 or 28 respectively. That does't sound like it's going to work with a 30T.

The sort of change you suggest would help you generally can't be made with a simple cassette change. (Not unless you're starting from extremes, at least.) I suggest you look at compact gearing (a new crankset, at the minimum) for a more substantial improvement in high gearing choices.

A triple would be most beneficial but also raises the likelihood that you will need new shifters (a new left shifter?), gs rear derailleur, and cranks. That's a big investment.

Try a midcompact 52/36 crankset with your 11/28 cassette.

gearing

Thanks for the feedback, I was just hoping a quick cassette change might do it.......much more cost effective.
I did change the front from a 39t to a 38t but don't think will make much noticeable difference...........

FYI, right now on ebay:

FSA Tempo Triple Road Bike Crankset 175mm 52 42 30 Silver 175 Cranks | eBay

You might need a new bottom bracket with a longer spindle as well, those can be gotten for $25 or so

That would be a major downgrade from OP's current crank, he would need to new front dérailleur and lever to run a tiple, plus I'm assuming OP is in UK paying for shipping it won't be as good of a deal.

OP just needs to find a comperable crank in compact and sell existing crank to recoup some of the cost.

A much higher end solution for a reasonable price: You can find Campy Record Cranks for under $100 on ebay, and get them triplized.

How often do you use 53/11? That's a gear that most amateurs including myself can manage without. A switch to 50/34 would reduce your maximum speed by 6%, if your cadence remains the same. But you would gain a 13% lower gear on the climbs.

Lose weight or More squats and lunges... You are just too weak for your weight.

If if you are strong but not recovering fast enough for steep hills, then do more HIIT exercise routines.

Or you can just ride more slow miles and get stronger the old fashioned way

For reference I'm currently 17.3 stone and I don't have a problem with a 53/39 and 11/28.

At a light 15 stone and struggling? HTFU.

Cheap to try a 12-30 cassette to see if it gives you enough low end. I've used them with 6600, 6700 and 7800 rear derailleurs w/o issues but it depends on your frame. The later 6700A is Shimano approved for 30t.

You don't say anything about where you live, how long and steep hills are, your level of fitness, how long you've been riding, etc. it's hard for anyone to offer advice without more info. For example if you're just starting out, riding more with some hill workouts might be all you need. At the other extreme if you are really experienced and in the best shape you plan on and you ride continuously on 6% mile long climbs, getting a compact or a triple makes sense.

get the shimano 12-30 cassette

if your RD will run a 28 it should (99% confidence) run the 30, just turn in the B screw. If you cant find that, use youtube.

I have run 12-30 with RD7700 (rated for 27 max)

If you need more gear, SRAM makes a 12-32 cassette, but you may actually need a new RD for that
Still, cassette and RD are cheaper than cranks

if you're running SRAM shifters you can go to a wifli derailleur and go as big as you want. (That's what she said)

Use that gear combo you have and just ride hills twice per week and base miles another ride per week. No cyclo-science, hills are your friends. Do not avoid them.

28 to 30 isn't likely to help much. The only sure thing it does is the added weight. Changing the front to something smaller is the way to go.
