19 Aug 2018
HI there,
Can I use these with the ST-5600 Flightdeck Shimano 105 shifters? Also what is the cost to send to New Zealand.
These are not listed to be suitable for 5600 and we have never attempted to use them.

Can I use the Sora adjustment block with Claris levers?
22 Jul 2018
I am trying to reduce the reach for my son. He has a road bike with Claris group set. Bike purchased in late 2016. Dawes Academy Road 650c. One adjustment block already in place. Can adjustment blocks be added to or stacked to reduce reach further? Many thanks RY
These should be able to be fitted as long as the previous block has host holes.

Can I use this Shim with shimano Tourney?
16 May 2018
Hi there,

From the information available there are no suitable shims to fit those levers.

I have a specilized ruby with shimano double breaks will this fit my bike?
06 Apr 2018
I rang specilized and they said they do 5mm and 10 mm shims, are these the 10mm? Thank you
Hi there,

These are the larger 8deg option from Shimano and will fit ST-3400, Shimano ST-2303 and Shimano ST-2300.

Hi can this be doubled up with other shims?
10 Feb 2018
Hi there,

As far as I am aware you can only fit one shim, fitting two would mean the second has no point of connection to the first.

Hi , can you buy extra shims to add to this ?
12 Nov 2017
i have already bought this item but it still isn't enough for my sons small hands. Can you add another shim to this to bring the lever even closer, thanks

Unfortunately this is the largest reach/angle adjust block available from Shimano, so to bring the lever even closer you would need to make something up custom I'm afraid.

do you stock the right hand one too?
04 Nov 2017

We do indeed stock the right hand too, these are SJSC part number 26993.

Can it be used with Shimano Claris ST-2400?

The ST-2400 Claris actually use the newer style of adjustment block the same as found on the ST-3500 Sora, we stock these are they are SJSC part numbers 33591 and 33590 for right and left.

Triple To Double?
01 Nov 2016
Shimano Sora ST-3400 Adjustment Block - Left Hand - 8 Deg - Y6LT24000

Does this item make a triple a double?

Or is it the other way around?

Unfortunately this is not what this adjustment block is used for, this just affects the angle of the brake lever making it easier to reach for people with small hands on when fitting these levers to compact bars.
