The last four shops I've worked at (alright just three I worked at, the fourth I owned and did much of the wrenching) Take a lot of time to make sure that the cust provided steerer cutting request is done right. Suggesting that the steerer is cut to a longer length then first asked for and the offer to recut to a shorter length for free after the cust rides the bike a while. On new build ups we've sold we would do this as a mater of course. The recutting is usually done at the free bike check up if we sold it. More then a few times each year we would have a cust want a different stem position after living with the bike a while. Some of these times we were glad that we had extra steerer to work with. Andy.
