Customer Reviews

ULTIMATE USE 30.9 Internal Shim is rated 4.7 out of 5 by 75.
Rated 5 out of 5 by from Good fit I used this so I could fit a 30.9 dropper post in a 31.6 steel frame, and I have had no problems with slippage or siezing in the frame all in all its worked perfectly.

Rated 4 out of 5 by from Seems flimsy but doesn’t the job Initially unconvinced a bit of thin plastic was going to work but went on anyway (or not ride) and was pleasantly surprised ... no slippage at all.

Rated 4 out of 5 by from Does the job. I needed this to convert an existing dropper post to a new frame. With a bit of carbon compound and some grease it did the job fine. Only 4 stars as it was a bit thin at the top and kept flexing as I tried to insert it. A larger flange would have helped in this regard. It has survived several roughish rides unscathed, with plenty of dropper post actuations.

Rated 1 out of 5 by from Not so good Needed this to colve a 30.9 reverb in a 31.8 frame - it fits, but it didn't hold the post in place well enough to stop it rotating

You would need the 31.6mm option.

Will this change a 34.8mm diameter to a smaller diameter?

Asked by: maracas
You will need to choose the size of your seat tube from the drop down menu. This shim will reduce the internal diameter down to 30.9mm
