- cutting carbon steerer tubes
and do it outdoors wearing a mask.
That can be a bit impractical, especially when the cutting guide is vice-mounted and the vice is bolted to a workbench!
I’ve done a couple in the garage (mask on) and swept up/binned the resulting dust. Hopefully I will not suffer a carbon-dust related demise…Posted 4 years agoTiRedMember
Electrical tape around the tube, add spacers, stem and metal 0.25cm top spacer. Dampen wear mask and cut.
Otherwise, off to the bike shop. Ride it a lot before you cut it. You can’t go up again. I’ve done about 1000 miles on my new bike and am still refining up and down by 0.5cm depending on race or non-race.
Hope the new bike is fitting better. Post a pic.
EDIT: as an aside. I cut the steerer on my beloved Merlin the month before it was stolen. So now the only part I have left resides on my garage door keyring as a reminder of my loss.Posted 4 years agoallthepiesMember
I used a brand-x guide from CRC, wrapped some tape around the steerer and used a fine toothed hacksaw. Goes through really easily and leaves a clean finish.
Do a practice cut high on the steerer to make sure you’re happy with cutting the actual desired length. If the practice one goes to poo then take it to a LBS 🙂Posted 4 years agomuddydwarfSubscriber
Ta for the info 🙂Posted 4 years ago
For clarification i currently have 25mm of spacers above the stem and 10mm below it. Only done 130 miles since i got it on Saturday so still experimenting with bar heights etc.
fit is better, 4cm shorter seat tube but i still have a short 70mm stem on it – must have very stumpy arms!
