|Carbon steerer and use of spacers||Ray M|

|I just got a Profile Design AC fork, which has a 1" carbon steerer. What is okay to use in terms of spacers with it?

|is the general rule. If you think you need more, get a stem with more rise instead.
Also follow manufacturer's instructions for installation of the reinforcing plug. Recent advice from pro mechanics is to cut the the steering tube to protrude 1 to 2mm above the stem, and place a 3mm spacer on top to reduce the chance of cracking from stem clamping pressure.

|Ok I've been told max of 1 cm for a 1 inch fork and 1.5 cm for a 1 1/8 in fork. That being said I have 2 cm of spacers on my 1 1/8 Columbus Muscle fork. I may lower it a bit so I can do what C-40 suggested. I also heard that his suggestion is a good idea.|
|2cm maximum..???????? Anyone seen the steerer fail??||MGS|

|I've heard this 2cm maximum quoted by every group. I have seen this printed out in an HSC fork I installed. I have not seen it listed with the fork used by Colnago.
Despite the 2cm maximum, I know many people, myself included, who use greater than 2cm.
Has anyone none or heard of a steerer failure at the headset due to too great a spacer???????

|not likely to fail, but it looks bad...||C-40|

|Definitely the Fred look. A higher rise stem is a better way to get more height. Too much stem rise though, and you're into the Fred look again. Proper frame sizing helps.|

|Even though I've heard about the 2 cm rule for cf steerers, has anyone seen the Team Bonjour bikes, the Time Frames with the time forks. I know they use cf steerers, but some of the riders have at least 30 cm or more of spacers on them....I wonder if any of their steerers have snapped, cuz we all know they've snapped the time magnesium faceplates on the cf stem.|

|FWIW, I did get a reply from the fork manufacturer (Profile), which also concurred with the 2 cm.
Thanks for all of the help!
