Ok,

So whats the smallest chainrings uou can get on a standard 105 5700 Chainset??

Currently set up as 50-34, but having tried out loaded panniers, well, people where right..

Could see it being an issue.. 😳

I’m pretty sure you won’t get less than a 34T, suspect they don’t exist. What’s the BCD?

Bigger cassette?

What woody says Nick. Bigger cassette would be wise.

11-36 Wiggins bike

even the best need spinny gears

Cheers All..

Much appreciated.

So I’m guessing I’d be better of with an MTB Chainset then?

You can get a 33t TA chainring but that’s not going to make a huge amount of difference.

Assuming you’ve got double specific STi shifters on the bike? Not 100% if a roadie front mech will work with a mtb double chainset.

Fit a 9-speed MTB mech and a 36T cassette. That’ll work with your 10-speed STIs.

I use an ultegra triple on my touring bike, 52-39-30 with an XT 34T cassette. Mostly on the flat and rolling climbs I can spin along on the 39′ but when things get steeper I use the 30.

Back in the day touring bikes were sold with 42-52 cranksets 😯
