Paul "Thumbies" are the original upright handlebar mount for bar end shifters. They do not include the shifter but are designed to be used with indexed bar end shifters from Shimano, Campagnolo, SRAM & others, this version is for use with Shimano shifters only. These shifters are readily available for 8, 9 & 10-speeds, & most have a friction option for everything else.

There are three versions available to pair with Shimano bar end, Campagnolo bar end or SRAM TT shifters. Each company has their own unique shifter boss fitting & they are incompatible with one another.

Mountain Thumbies fit standard mountain bike handlebars but will work with almost anything that has a 22.2mm (7/8 inch) diameter. The shifter boss is raised from the bar to give clearance for bulky two-bolt brake levers & the hinged clamp makes installation easy.

- Finish: Anodized

ProsDoes the job really well
Enabled me to swap the drop bars on my Dawes Galaxy for straights while retaining the use of the original bar-end shifters. Open jaw design means easier fitting / removal. Expensive but being made in the USA that is to be expected. Good quality and an excellent accessory.
Good but maybe cheaper alternatives are better

ProsLevers better than pods
I bought these rather than JTEK or SJS cheaper alternatives as they project more from the bar and will sit over the top of a brake lever. In fact once they are fitted you end up moving them more centrally on the bar so that the levers do not intefere while braking, so maybe the cheaper ones would have been better. That said, these do have a distinct advantage in that they are open-jaw & can be removed without removing brake lever and grips and bar ends - this means that when I pack the bike to go on a plane the shifters can be detached from bar, hang free, and be wrapped in bubble-wrap, which should protect them nicely.

Quality is good, they do the job, sod those rapid-fire pods.

ProsEasy to fit, work well
My apologies for getting back to you so late, but before I could give proper feedback I had to do a few test rides. Everything else was very much okay. No complaints about your service either. They arrived sooner than expected, so nothing more to wish for.

The product itself: Damn good! They are very easy to fit and place the actual shifterpart in just the right place. Way better than the original Shimano thumbies, although it can't reach the ergonomic quality of the STI unit. It's also not as fast shifting as the modern STI units, but its super bombproof and will probably outlast every other shifter combo that's on the market today.

One advantage that's also worth mentioning is that it can make combinations of shifting parts from different brands work. For "walletary" reasons I use a mix of shifting parts from different brands like Shimano, SRAM and BBB. My former XT STI's did the job but not always that good. Now, combined with DuraAce timetrial shifters, it works absolutely flawless. (For globe travellers this info might come in handy also.)

But: If I had known that regular downtubeshifters also fit on these adaptors, I wouldn't have gone through the trouble of getting timetrial shifters. Maybe that's something worth mentioning on your website?

So, thanks SJS Cycles for the quick service and for a top product.

Fitting On Drop Bars
18 Jan 2017
Hi, I'd like to fit these on some drop bars (don't ask!) but they seem to measure 24mm rather than 22.2mm. Do you think I'd be able to fit the thumbies to these bars, bearing in mind that I'd have to squeeze them around the curve so they'd be on the flat part of the bars.

These thumbies unfortunately will not fit your bars, most flat/straight bars are 22.2mm and most drop bars are 24mm. All we can recommend is going for a set of the 31.8mm options and run them pressed right up against the stem on the larger section of the bar. these are SJSC part number 29187.

We don't currently stock them but they are available so we can get hold of them. As we'd have to order them as a special order item the order would have to be placed over the phone.
