## Questions & Answers

**Q: Anyone else getting an odd smell coming from the break pads while riding this bike? Kind of similar to the smell of burnt hair?**
A: Before use, and every 6 months or so, you need to lubricate the felt brake pads with a silicone lubricant, such as the WD-40 Specialist Silicone Lubricant.  For some reason, this isn't mentioned in the manual.  Note that this only applies to the felt brake pads on this bike; leather brake pads on some of the other models need to be lubricated with 3-in-1 oil.

**Q: What length inseams will this bike accommodate?**
A: I'm 5'1" and while I can use the bike fine, I have everything set to the lowest size setting and it's still a bit of a stretch for me. I feel like if I were 2-3 inches taller it would be perfect. But I'm also realistic and I think there's probably not a bike out there that would fit me perfectly given my size since I have this problem with a lot of things in my life.

**Q: Does this bike has clip-in pedals?**
A: I put clip pedals on this bike taken from my road bike and they work fine.

**Q: Is anybody else experiencing problems with the resistance setting? I am lacking the gradual resistance. It goes from easy to almost lock up even if I turn the nob in real slow small increments.**
A: The manufacturer recommends removing the brake felt pads and roughing them up with a wire brush.  I did this and sprayed them with silicone and replaced them.  I also sprayed the felt pad under the adjustment knob with silicone which is easy to overlook.  This has greatly improved the resistance setting.
