STI Shims 5mm to 10mm

More of a quick review than anything.

I have a Shimano 5700 groupset on my bike and the levers came with 5mm shims as stock. I don't have the world's largest hands and had always been aware of the slight discomfort, for the want of a better word, when braking from the hoods. When braking from the drops, I always wished that my fingers were a few mm longer.

Recently, whilst overhauling my bike, cleaning, regreasing, new cables and bar tape, I found that I had lost one of the 5mm shims in my levers. Couldn't find it anywhere, so decided to buy some 10mm shims as replacements. What a world of difference! I don't know if they are actually 10mm, I haven't measured them yet, but those few extra mm really make life easier. It all depends, for me personally, where the first joint of my fingers sit. With the 5mm shims, the levers fell halfway between my finger tips and the first joint in my middle finger, now with the 10mm I can hook my finger around the front of the lever, which makes braking feel more controlled and natural.

Well worth the few pennies I spent on them. So, if you have the same problems as I, go buy some.

A very helpful review and I'm glad you found a good, cost-effective solution to your discomfort.


It's worth noting that the 5700 (and 6700 Ultegra and 7900 Dura-Ace) series levers did have quite a bit larger diameter hoods than the previous (5600/6600/7800) and indeed, the newer (5800/6800/9000) series levers and so this will be of particular interest to those running the first style of lever I described.


Do you have a link (or a part number) for those wanting to purchase the same shims?

I believe that the 10mm dimension stated is the amount of lever tip change. As in the lever tip becomes 10mm closer to the handle bar. Andy.

Thanks, Matt!

Yeah, it was an annoyance as it was previously, like that shirt that you can't get the top button fastened without causing suffocation, or that pair of trousers that you have to wear a belt with to stop them riding down to your ankles. Not a major annoyance in the grand scheme of things, but now with the newer shims, there is a world of difference.

You are quite correct regards the previous and latest 105 hoods. I definitely noticed that difference too. Also, the 5600 and the 5800 STI's are more enclosed than the 5700. Not that it makes a huge difference, but they are definitely more protected from the elements than the more open style of the 5700's. They obviously went back to the better design after the 5700's. Typical that I have the 5700's

Links are below:

SJS Cycles. Shimano Adjustment Blocks - All Models

I have found SJS Cycles to be excellent for all those small parts you need but can never seem to find.

The 6700 shims, for the left and right levers, are on the first row for the 5mm and third and fourth row for the 10mm. These are compatible with 5700, 5703, 6700 and 6703 shifter. Other model shims are here, too.

It would seem it, Andy, as it's changed the feel and reach of my levers quite a lot.
