Hi Kathy. We only sell a handful of parts individually, which are mostly the pieces specific to our bikes. Unfortunately, we do not sell saddles. While the saddles that come on our bikes might have a Montague logo printed on them, they’re not specific to our bikes. Any standard bicycle saddle should have the same rails underneath for mounting to the seatpost on your bike.

The bikes are in good shape but their saddles need renewal.

I don’t see any replacement seats on your store. Are they available? It would be nice to stick with Montague equipment.

There’s normally a fair bit of torque on that seat clamp bolt, but it certainly should be possible to remove it and swap the saddle. If you’re not able to do it with the hex key you have, a local bike shop should be able to loosen it. Feel free to give us a call if you’d like to discuss – 800-736-5348

Unfortunately, no. That piece is the seat tube from the rear half of the frame which extends up through. The front half of the frame simply slides down over it.

For the older pre-2012 bikes, is the seat tube adjustable by unlocking the lock nut and adjusting the seat tube that is slightly narrower than the frame?

The seat tube is too high even with the seatpost at the lowest setting and I wondered if this part of the bike was adjustable?

Montague bikes from 2012 to present use a 30.0mm seatpost. If it’s pre-2012, it would be 27.2mm. If you want to use a specific post that is not available in 30.0, I would recommend getting a narrower diameter like 27.2 and using a seatpost shim: https://www.google.com/shopping/product/11377148020376686262

The officially listed weight capacity in our owner’s manual for all models is 250 lbs, but that’s really on the conservative side. Up to about 300 lbs is fine. It’s really the wheelset that limits weight capacity, and our frame has been tested to handle even more than that. So, you could replace the wheelset with higher spoke count wheels to handle more weight (300+ lbs) if necessary. At 285 lbs you should have no problems.
