Rated 4.2 out of 5 by 5 reviewers.
Rated 2 out of 5 by ONly for flat bar. Only really for flat bar, on my high rise bar they marked as the go around the bends. You can split them open a tad while your doing this but then you may as well just get a split shim and save the hassle. Gets 2 stars because they are nicely machined. I have lost mine and i am glad. 15 June 2012
Rated 5 out of 5 by good buy Проставки-переходник для выноса,помогли мне подружить руль 25.4 и вынос 31.8.Резинки наверно,чтобы не скользили кольца.Необходимо снимать все рукоятки с руля. 10 June 2012
Rated 5 out of 5 by Probably a little OTT for what they are but they work perfectly with the seemingly random combination of a 25.4 mm Funn bar and a 31.8 Truvativ stem. 04 August 2010
Rated 5 out of 5 by Perfect for a 25.4mm bar used in a 31.8mm stem I needed a shim for my EA70 Monkey Bars (25.4) to fit the integrated stem (31.8) on my Travis Triples. Found these, fit perfectly and do the job as needed. I'd recommend these unless you want to pay £40+ for new bars. 01 May 2010
Rated 4 out of 5 by good get it if you need it because looks good and is cheaper than a new stem or handlebar 06 September 2009

These shims are machined to specifically fit a Straitline stem, however compatibility with other models should enable an adequate clamping force.
