Bike Stem - 40 Degree Rise (Any Problems With This?)

Is there any major issue going to a 90mm, 40-degree rise stem?
Original stem is 105mm, 6-degree rise.

I've been using a stem riser, but I damaged it & had to cut it off, so the bike shop suggested an angled stem would be preferable to a riser.

I have to ride a larger frame due to long legs, & I like to have the seat & handlebars close to level.

You doubt the advise of your local shop? Why? they can see your bike in person, I Can not.


Another alternative is A New Fork with the steerer tube left full length.
(i have to guess you have a threadless type fork/headset..

One of the functions of your current bike is to help you to determine what you want your next bike to be like. Since you didn't like the stem riser, why not try the angled stem? If that doesn't work for you (and I'm betting it'll be fine), then you can try something else.

I don't doubt their advice. I was just searching for the steepest angled stem I could find on the internet, and I was wondering if the one I found would work. They had 3 lengths, all 40 degrees.

The bike shop found a couple stems which were 30 degrees from the places they deal with but no 40 degrees, so I thought I'd search the internet. Right now I have an adjustable stem on at 40 degrees, but they just let me borrow that to see if I liked the angle, which I do. They don't recommend the adjustable stem permanently.

PDX has 100 bike shops, have you Not checked around?


Import? SJS Cycles in UK has this one I am considering because it angles up from the back.

https://www.sjscycles.co.uk/stems/11...black/?geoc=US

Most angle up starting from ahead of the Steerer tube and use the Cap , which remains visible
to do the Headset pre load adjustment, before tightening it around the steerer tube.

https://www.sjscycles.co.uk/stems/th...110mm/?geoc=US..

I already have used the BBB BHP 21 quill stem raiser .. wiggle.com | BBB BHP-20/21 Stem Extender | Oversize Stems ..

I am still using the OEM adjustable angle stem That has been on the bike for 12 years

But the design [ ITM , CNC , Italy] is quite solid in how it Locks into its Upward angle.


NB this Is Not a set up I ever take off road , IDK what you did to break yours .

I haven't bought my new stem yet, I am currently using a Ritchey adjustable stem set at 40 or 45% and it is a 100 or 110mm long stem.


I have my eye on these two stems:


Procraft SL 31.8 Stem 40 - Max length 130mm


Procraft SL 31.8 Stem 35 - Length in 150mm or 180mm
