@berlinonaut cheers - helpful !
If you've got time:......
1. How do you rate the photo-diy - just out of interest ?
Also:
1. In theory, do you think i could replace the listed Batavus seat post and incorporate the by-schulz into the instructions as a replacement component part ?
2. I don't get how the stem clamp is held in place on either this or the dutch model. Do you know how these are retained in position ?
3. If i understand it correctly there's quite a bit of work going into creating a handlebar clamp head. Could i not attach an ahead instead and then a suitable riser ?
4. I see they glue two rings to centre the handlebar within the handlebar clamp but it seems like this method will still have the problem of needing to centre stem in relation to front wheel everytime used - is that correct assumption ?
2. Where you say the by-schulz offers a lot of options and avoids some typical issues:
Options and issues already mentioned:
Positives:
Presence of a height gauge
Ability to incorporate ahead / riser / suitable handlebar clamping
Negatives:
Raised height limited in relation to length of straight section of Brompton stem
Potential failure of a stem QR with no locking
Potential failure of a handlebar clamp QR with frequent use
Need to correct the front-facing / front wheel alignment upon each use.
Do you see the by-schulz negating any of the negatives above ? Or enable any options not listed ?
cheers - appreciated. s
