pogie Posted December 23, 2011 Report Share Posted December 23, 2011 As you may have read in my 1st post I just bought this bike in attempt to get "back into" riding trials. So I stripped this bike down to check over the components, everything was pretty good cept for the BB and cranks which were loose, the left side crank arm was near falling of actually. I had to bleed the Echo rear brake. I replaced the front Avid7 with a Hope Monotrial. It doesn't grab as well, I don't know whether it's the little bit of oil on it from manufacturing or the fact the BB7 had a 203mm rotor and the Hope had a 160mm rotor. If it doesn't get better in a few rides I'll purchase a adapter and go back to the 203mm rotor. The rear rim brake grabs something fierce. So did I mention I haven't really ridden any sort of "stunt" bike in about 4 years? I've been rolling around on a nice big comfy comfort mountain bike, and Ive been spoiled by a 1000watt electric cruiser.. I've gotten lazy, put on about 30 extra pounds and lost allot of my agility. I got on the Zoo! and went for a ride down to the beer store (this is going to stop by the way) hence why I bought the bike. It felt good to be back on a trials bike, it was sort of uncomfortable but it's one of those things I have to get used to being on again. I rode for about 15 minutes just along the sidewalk scaring to death any pedestrians with the freewheel noise. (My trials bike years ago was built up of mainly mountain bike parts, so it was relatively quiet, this front freewheel is quite the change for me) I didn't really like having to lean all that way forward on this bike, but I kept reminding myself that once I am a little more limber I'm going to spend most of my time on the back wheel in the vertical position. I expect my experience to better, it's minus 1 degree outside, and I'm wearing 2 layers of clothes to keep warm. More to come! Quote Link to comment Share on other sites More sharing options...
bing Posted December 23, 2011 Report Share Posted December 23, 2011 is the hope brake brand new? are the pads new also? if so it will need bedding in, and won`t grab as well as your bb7 until it is. A hope mono trial is miles better than a bb7 in my opinion. Quote Link to comment Share on other sites More sharing options...

Laurence--Trials Posted December 23, 2011 Report Share Posted December 23, 2011 The hope will need to bed into the disc, this will require lots of riding around with the brake half on, can take quite a while and be quite energy consuming, try not to let the brake over heat though, just short intervals of riding around. People sometimes use water to bed in the disc, not sure what this does though.. Also the fact that you have gone from a 203 rotor to a 160 will make your brake less powerful due to the fact that you have less leverage, if you want more power from your hope then i'd get an adapter (or steal the one off your avid bb7) If your going from a bb7 which is a good brake anyway (203) to a 160 hope then i dear say the power would be worse, only way to find out would be to bed it in. I'd suggest keeping the 203. Quote Link to comment Share on other sites More sharing options...

People sometimes use water to bed in the disc, not sure what this does though.. I found that if you ride along and slam the brake on/off it beds quicker, but it's all down to personal preference. Also you're not supposed to use water as it can crack the rotor because of the extreme changes in heat, I heard it's not good for the pads either but don't know why to be honest.

Bull shit, i've done it countless times, especially on my 160 rotor when i put water on and it turns instantly into steam. Quote Link to comment Share on other sites More sharing options...

I'm afraid its not bull shit, I'll agree its incredibly unlikely. But rapidly changing the temperature of anything is never good. 1 Quote Link to comment Share on other sites More sharing options...
Azarathal Posted December 23, 2011 Report Share Posted December 23, 2011 Wrap a spoon handle in duct tape and hold it with an oven glove Heat it over the hob for a good 3-4 minutes Run it under cold water Spend the next few hours in hospital having shrapnel removed from your face. I know it's different with a disc brake but I still wouldn't want to get it too hot "just incase". Quote Link to comment Share on other sites More sharing options...

A hope mono trial is miles better than a bb7 in my opinion. I absolutely disagree with this statement. BB7 is miles and miles better than hope for trials. Better bite by miles. Better hold by miles. Unless you get tech levers better 'dial in' of reach and modulation. Cheaper. No stoopid oil to get on yer discs. No bleeding of said Stoopid oil system. Bed in Quicker. Lighter. Better. Put your Avid back on. Quote Link to comment Share on other sites More sharing options...

Not my words, it's what it says in Hopes instructions, plus I believe I said can not will and extreme changes in heat can cause cracking in metals. 1 Quote Link to comment Share on other sites More sharing options...
