I just figured 2 stupidly simple options...
a) The same way I can jack the rear with a 14in tube while on the side stand, I can jack the front with a 35in 2x4 under the right side of crashbar!
I would cut a wedge in the 2x4 to prevent the tube from slipping out. Keep the bike in 1st gear removing the slack. Assuming I cracked loose any axle or tube pinch bolts, calipers, and the axle itself prior to jacking, the tripod formed by the rear wheel, sidestand and 2x4 would likely hold fairly still for the low torque needed to work the wheel or forks off.
b) I could probably just lift the front with regular stand (might need to do in raised by rolling it on planks on each side of tire, due to front sag), then position 2 posts under the crashbar, and lower down the stand. I'm aware of the risk of moving sideways, so the 2 posts would be joined somehow, similar to picture in post #3. It's just more difficult because the crashbars are further forward and wheel is obstructing.
I wish t-rex could tell me if their triple clamp stand can work with hepco becker crashbars.
If you are an owner of this stand, can you please upload a picture showing the clearance left?..... Thanks.
