Prossolidly built, no moving of parts or handlebar, big bolts for big hex keys, reasonable price
I own 2 Thorn stems in different length and angle and I love them! Excellent build quality for very reasonable money. The bolts have large heads to fit the bigger hex keys, which I find very valuable. I would love to see more different new Thorn stems, even for 31,8 bars!! thanks

I purchased this stem to hold my Crazy Bars from Velo Orange. I needed the 1" clamp and 1 1/8 steer tube setup. SJS Cycles is always prompt about shipping and there products are good. They stock many items that I don't or can't find else ware. Thank's much

ProsStrong, simple, 40 degree angle.
Simple, elegant, light, strong, alloy, durable, excellent.

I used this to replace an adjustable stem. I had a big angle on that stem, (50 degrees), and the stem itself was just not very secure or strong. I was experiencing a lot of creaking, no matter how tight the bolts were, plus the stem always looked aesthetically clunky and ugly and added considerable weight. There are not many fixed stems around that I could find to replicate such a steep angle but this Thorn stem does the trick admirably. I'm most happy with the replacement. It has lightened up the front end of my bike, visually, weight wise, and the bars are now a LOT more secure. No more creaking, no more unnecessary clunky metal! 10/10!

yes provided your bars are 25.4 clamp (which used to be standard)
What H/Bar Clamp Size Is This?

Hi, the handlebar clamp size for this stem is 25.4mm. Apologies for the confusion as this should be part of the description. Regards Jamie
